It follows from the comments above that I am quite impressed by the formation of this Program and by the number and quality of the results already obtained after one year. I am convinced that it will be quite successful in providing a better understanding of the difficult nonlinear problems involved in plasma turbulence.

UCSD

The modern computer technology allows not only simulating turbulence plasmas, but also handling a large amount of experimental data obtained from more than a hundred of spatial points in turbulence plasma. Then the experimental data can provide comparable information to present simulations. Turbulence theories now can find a way to be verified, and can be stimulated with the well-processed experimental data. In this sense, it is the very appropriate time to start the studies of turbulence in a coordinated manner. This project is timely, and is led by innovative scientists. The project has a very large chance of pioneering a new field of modern physics in the 21st century.

1. Overview of the project

The report hereinafter concerns the Grant-in-Aid for Scientific Research “Specially

Promoted Research” with the title of STRUCTURAL FORMATION AND SELECTION

RULES IN TURBULENCT PLASMAS. The project involves seven members of Japanese

scientists, the principal investigator, Prof. Sanae-I. Itoh (theory, Kyushu University), Drs. K.

Itoh (theory, National Institute for Fusion Science (NIFS)), A. Fukuyama (simulation, Kyoto

University), M. Yagi (simulation, Kyushu University), S. Shinohara (experiment, Kyushu

University), Y. Kawai (experiment, Kyushu University), and A. Fujisawa (experiment, NIFS).

Profs. P. H. Diamond (University of California, San Diego), and K. Hallatschek (Max-Planck

institute) are the cooperators in the theory branch of the project. The document describes the

discussion on future plan of experiments concerning with the project, and the evaluation on

the results achieved with the project in fiscal year 2004

The project aims at establishing the principle of structural formation in turbulent plasma.

The feature of the project is the integrated approaches of. theory, simulation and experiment.

Consequently, well-coordinated works of the three branches will be a key factor for the

success of the project. At present, deeper understanding of plasma physics is now really

requested for many fields of sciences and technologies, such as astronomy, life-science,

nano-technology, plasma processing, energy production, and so on. Therefore, the project is, I

believe, quite contemporary and timely.

In the last fiscal year, a number of papers (including 23 scientific articles that are directl

outcome of the project) and presentations (including 93 communications in international

conferences and workshops) have been already published in the project. It is worth a while to

specially note that a review about the zonal flow, entitled zonal flows in plasma, is published

in Plasma Physics and Controlled Fusion. The fusion simulation project, named TASK,

initiated by he project members is now threatening the leadership of the corresponding US

activity according to DOE statement. In the experiment, the dual heavy ion beam probe

measurements succeeded to confirm the presence of the zonal flow for the first time in

toroidal plasma (Physical Review Letters 2004). These works are fully appreciated in both

quantity and quality as the first year achievements.

The experiment in the project aims primarily at verifying predictions of theory and

simulation, and collaterally at finding new phenomena. Two devices are involved in

experiment of the project: a linear plasma device in Kyushu University and a toroidal device,

51

named Compact Helical System (CHS) in NIFS. This fiscal year 2005 is a crucial time for the

project since the largest budget for the five years comes to determine the future of the project.

The most of the budget will be spent on the construction of a new device for turbulence study;

the linear machine in the Kyushu University is to be appropriately modified for the aims of

the project. The meeting during 7-8 June was held mainly to check and review the present

design and schedule of the experiments. A report on the general view of the project and two

presentations on general and detailed aspects on the experiment are presented in the meeting.

2. Overview of experiments

Turbulence is a long-standing physics problem that has no well-paved road to approach.

The enormous degree of freedom of turbulence obliges multi-points measurement with

sufficiently high-temporal resolution. Although the huge amount of data can be handled by

modern computer technology, the immense mass of data mystifies researchers in a digital

labyrinth if they step into without a proper methodology. Sophisticated diagnostics is to be

developed to give sufficient precision in measurement of (and to minimize perturbation to)

delicate structure of turbulence, and advanced technique is needed to extract nonlinear process

and structure in turbulence from the huge amount data. The key issues for experimental

approach to turbulence are to develop diagnostic technology and analysis tools. During the

five years of the project, experimental methodologies of turbulence studies are to be

established, including developments of analysis tool for turbulence characteristics, and

diagnostic technology.

In CHS experiment, the heavy ion beam probe (HIBP) is the diagnostics to investigate the

turbulence and nonlinear structures of plasmas. The diagnostics is to access the plasma core,

without any obvious perturbation, where the temperature is too high for the traditional probe

to insert. The major target of this fiscal year is to identify zonal magnetic field, making

advance of the last year’s achievement of the zonal flow detection. Besides, the studies of

turbulence and structure will be continued. Studies of Alfven Eigenmodes should be

particularly encouraged, because their importance in the dynamics of burning plasmas is now

widely recognized.

The analysis tools should be developed in parallel with on-going experiments. Particularly,

bicoherence analysis is being applied on available experimental data. Its application on probe

data of JFT-2M tokamak found a significant nonlinear coupling between background

turbulence and Geodesic Acoustic Mode (GAM) in a statistically rigorous manner. The result

makes the interpretation of the bicoherence analysis more obvious and demonstrates the

capability to extract nonlinear process in turbulence.

The wavelet analysis is being used to extract characteristic s of turbulence. Its application

on the internal transport barrier of CHS succeeded to reveal intermittent characteristics of the

turbulence and a causal relationship between turbulence and zonal flows. The result

demonstrated the ability of the wavelet analysis to extract the intermittent behavior of

turbulence. The corollary of these results suggests the necessity to establish significance of

wavelet bicoherence analysis to visualize intermittency in nonlinear wave couplings that is

important for turbulence of both plasma and neutral fluid.

In the dawn of nuclear fusion research, generated plasmas were of low temperature that

might have provided a good environment for plasma physics studies with help of peripheral

52

technologies. While it is about to realize a burning plasma in ITER at present, laboratory

plasmas of low temperature are being revisited for fundamental understanding of the plasma

transport and turbulence. The excellent accessibility and mobility of such plasmas allow

multi-channel measurements for physics experiments. The data can be handled by

well-developed modern computer technology. The laboratory experiments for this direction

are easily found over the world, and the project is in a good collaboration relationship with

two of such groups, CDX in University of California, VINETA in Max-Planck institute.

In the last fiscal year, the 192 ch. digitizers were purchased to prepare the multi-points

measurements in the Kyushu linear machine. The multi-points measurement is planned using

hundreds Langmuir probe arrays. Mainly three kinds of probe arrays are being designed e.g.,

azimuthal arrays, radial arrays, and two-dimensional arrays. A two-dimensional manipulator

to support precise probe positioning is now being purchased for accurate measurements.

Three types of new antennas were made to aim at producing turbulence plasma. These were

reasonable investments for forthcoming experiments.

Heavy ion beam probes are also planned to be installed. The diagnostics will provide,

possibly, simultaneous measurements of density, potential, magnetic field and their

fluctuations. Symmetric field of a linear machine provides a good environment for HIBP to

detect magnetic field and its fluctuation. Therefore, HIBPs will give a chance to identify the

zonal magnetic field or meso-scale dynamo in a complete form, as well as zonal flow. Besides,

the comparison between the HIBP and probe measurements, for example, will give

information of degree of disturbance accompanied with the probe insertion and the accuracy

of the probe measurement on the space potential.

The Kyushu linear machine is now under consideration for modification. The principles of

the modification are to provide stronger magnetized condition by increasing the magnetic

field strength, and to supply a more unstable condition of drift waves by extending the length

of plasma column. These conditions could give an easier condition to realize plasma of strong

turbulence state. Simultaneously, the chamber is modified to give maximum accessibility and

mobility for assumed physics experiments. The module structure of the chamber is highly

recommended. The new ports are arranged for better circumstances for multi-probe arrays and

HIBP measurement.

Planned experiments in the Kyushu linear machine are to identify fundamental nonlinear

processes to generate a structure in turbulence plasmas. Several concrete ideas of the

experiments are i) identification of turbulence structural factors, S(k, ), and their coupling

strength, ii) two dimensional measurements of the turbulent field and their two and three

points correlations, iii) research on field generation mechanisms e.g., turbulent Reynolds

stress, iv) identification of quasi-two-dimensional properties, v) determination of zonal field

pattern and causal relationship with turbulence, vi) interaction of dressed test mode with

background turbulence, vii) HIBP measurements and zonal field identification, and so on.

3. Comments on experiments in Kyushu linear machine

The key issues for the experiments in the Kyushu linear machine are to achieve turbulent

states, to fabricate hundreds probe arrays and heavy ion beam probes.

In the Kyushu linear machine, realizing the plasma having relevant turbulence characteristics

53

is the subject of the top priority. The definition of turbulence must be carefully determined;

noisy fluctuations derived from helicon source must be distinguished and only the turbulence

derived from plasma nature must be paid attention. Time scale is a key to distinction; the

turbulence correlation time should be shorter than the other time constant, for example, transit

time in axial direction. In the linear machine, collision with neutrals is a primary factor to

control plasma properties. The presence of neutrals may be an annoyance for the plasma to

develop to the strong turbulent state. Particularly recombination process at the end plate and

associate recycling increase the neutral pressure at the end of the column, and non-uniform

neutral distribution prevents the plasma from quasi-two dimensional turbulence states.

Therefore, some method to reduce neutrals must be contrived at the edge of the column.

It is good news that blue mode was obtained in the present linear machine just before the

meeting. The next issue is to explore turbulence states with less neutral. Using higher

frequency helicon sources will help to find such a state owing to its dispersion relation.

Higher vacuum pumping will give a more active way to expand the plasma operational

regime. It should be cautious, however, that in low-pressure situation the plasma production

process in a helicon source becomes unstable. Survey of turbulent states is the issue of highest

priority to be solved immediately, at latest within the first half of this fiscal year, October

2005. Fixing the target turbulence state is the basis for the other subjects, i.e., modification of

the linear machine and fabrication of the probes.

The modification of the machine is being planned to extend plasma length and magnetic

field strength. The length of vacuum chamber should be carefully decided together with

examining the results of searching the turbulence states. The length could be decided by

taking into account the minimum numbers of ports required for assumed experiments if the

present machine is sufficient to obtain the turbulent states. The numerical linear device, that

the simulation branch is now developing, should be completed in a hurry, in order to suggest

proper ways to modify the linear machine. Some devisal could be incorporated into the new

machine to reduce the neutral fraction, particularly at the end of the plasma column. For the

construction of the coil system and the vacuum chamber, the accuracy of their position must

need deliberation, since any displacement causes unexpected deviation of actual magnetic

field to lead to measurement errors.

Another important issue for physics experiments is to fabricate probes. The target plasma

properties give constraints on the basic design of probe systems. The probe systems including

electric circuit should be made to cover the frequency range of turbulence, and the channel

separation of probes should be shorter than the characteristic wavelength of turbulence. Probe

endurance to heat load is also dependent on the plasma parameters of target. The probes

should be designed and fabricated to minimize the effect of the probe insertion. Development

of new types of sophisticated probes is encouraged in addition to ordinary probes for on-going

or near-future experiments. The balance of expense between the device modification and the

manufacturing probes should be carefully considered and optimized. Try-and-errors in

fabrication processes of probes should be taken into account.

Surely, the installation of HIBP will extend the possible physics experiments in the linear

machine. However, the HIBP application on the low-temperature plasma is challenging. This

is because the electron temperature of ~3 eV may be insufficient to produce the ionization of

the beam if the traditional alkali ion beams are used for the HIBP. The development of

54

alkali-earth beam as well as additional method to increase electron temperature of the plasma

may be essential for HIBP measurements on the low temperature plasmas. An auxiliary

method should be prepared to increase the electron temperature of the plasma, for example,

launch of electron cyclotron resonance heating.

Even in the phase of construction, experiments durable in the present linear machine must

be continued, as well as developing the analysis tools. The finite time and budget of the

project may not afford to accomplish all the assumed experiments. Rearrangement of

experimental plans will be necessary by ceding the innovative experiments in the future

projects. The candidate of the innovative experiment is that on interaction between dressed

test mode and background turbulence. The concept of contingency should be respected since

the schedule often tends to be delayed and a novel project tends to suffer from try-and-error

processes. A part of the budget of the next fiscal year must be regarded as contingency

reserve for the project.

It should be emphasized that the success of this research project is doubtless, considering the

start-up and advanced achievements, even if some of innovative plan will not be tested under

the constraint of the given budget and period.

4. Concluding Remarks

The modern computer technology allows not only simulating turbulence plasmas, but also

handling a large amount of experimental data obtained from more than a hundred of spatial

points in turbulence plasma. Then the experimental data can provide comparable information

to present simulations. Turbulence theories now can find a way to be verified, and can be

stimulated with the well-processed experimental data. In this sense, it is the very appropriate

time to start the studies of turbulence in a coordinated manner. This project is timely, and is

led by innovative scientists. The project has a very large chance of pioneering a new field

of modern physics in the 21st century.

The key point in executing the experimental project is to produce the plasma in right regime.

The r-f heating induced and the neutral caused turbulence are to be avoided. Also the

suppression of the turbulence due to the short confinement time, namely the transit time must

be taken into consideration in choosing the device length

The project includes three essential aspects of broad interests for modern sciences and

technologies; i) to develop advanced theories and simulations for the turbulence, ii) analysis

tools for nonlinear processes and structures, iii) turbulent plasmas and intelligent diagnostics

to visualize the reality of turbulence. The outcome of this project, including planned

publications, will be a monumental achievement of the modern physics, symbolizing the

success of the project. I hope that all the members involved may find their pleasure in taking

part in the project.
