Goal is to establish APC by Spring-early Summer 2007 - Dir./AD/TD in weekly discussions on missions & personnel assignments

- PPD and CD will have to be brought at appropriate time


Coordinate and conduct accelerator R&D aimed at next-generation and beyond accelerator facilities

Provide accelerator physics support for existing operational programs and the evolution thereof

Train accelerator scientists and engineers

Provide leadership and coordination in establishing the necessary facilities for a broad range of accelerator R&D that can be accessed by both Fermilab staff and the world HEP community

Accelerator Physics Center: Mission Accelerator Physics Center: Mission


The goal of the Accelerator Physics Center is to provide enhanced emphasis on accelerator R&D activities aimed at Fermilab’s future beyond the end of current decade. The APC will provide both a physical location and

an org. structure that can accommodate accelerator scientists and engineers, either from Fermilab or outside institutions.

The APC will contribute to improvement of performance of the existing accelerator complex, and the development of new technologies and accelerator concepts that could enable new forefront facilities beyond the current decade.

In support of this primary goal, the APC will also increase Fermilab involvement in the education of accelerator scientists and engineers.

Accelerator Physics Center: Goal Accelerator Physics Center: Goal


APC: Specific Programs APC: Specific Programs Programs that will be initially organized and managed by

the APC, in either a primary or supporting role, include: Accelerator physics for Run II, Proton Plan & SuperNuMI (supporting) Simulations, design support & beam experiments for ILC (supporting) Development of instruments for, and coordination of participation in,

commissioning, beam studies, operations, upgrades at the LHC (primary) HINS conceptual design and accelerator physics, including design and

development of experiments and test facilities (primary) Muon collider R&D, including design and development of experiments

and test facilities (primary) Development of generic theoretical and simulation tools for advanced

accelerator calculations in areas of energy deposition, beam-beam and space-charge effects, linac emittance evolution, etc. (primary, w/CD)

Designing and coordinating programs of advanced accelerator R&D at the NML facility and possibly elsewhere (primary)

Accelerator theory and education: Host the USPAS Office, Accelerator PhD program, Peoples Fellows, and other accelerator education initiatives (primary)


APC: ResponsibilitiesAPC: Responsibilities Following its creation the APC will assume direct

responsibility for management and coordination of advanced accelerator R&D programs as described above.

The APC is not imagined as having direct operational responsibilities for beam-based test facilities these are expected to be the responsibility of AD.

Both the AD and TD will provide engineering and technical support for APC, and AD and TD staff will participate in APC activities.

The APC will retain responsibility for coordination of inter-institutional collaborations in Adv.Accel. R&D In particular, the APC will work closely with the Argonne

Accelerator Institute to coordinate mutual undertakings in accelerator research


APC: People APC: People The APC is imagined as being comprised initially of a

core of directly assigned persons, derived primarily from the existing AD/Accelerator Physics Department, and augmented by significant numbers of participating staff from AD, TD, CD and PPD. initially ~40 directly assigned and many in (…) number of direct assignments is expected to grow as Run II

Experimental AAR&D in APCExperimental AAR&D in APC Three groups anticipated, with quite different status:

AARD at NML with 250-800 MeV e- beam• no linac yet (first beam in FY07-08)• AARD plan not finalized yet (ongoing)• Leadership exists, the Group has to be created

High-intensity 60-90 MeV H- Linac at MDB• Facility exists, 325 MHz RF power Dec’06, 1st beam in 2007

(RFQ)• R&D plan well established• Group exists in AD/Accelerator Physics Department

Muon Collider R&D at MTA• There is ongoing program at MTA to be greatly expanded• R&D proposal on the table• Existing MC Task Force as base of the future Group

Disclaimer: these activities, on the time scale we are discussing, require FY07 funding for the Lab commen-surate with the President’s Budget request. If we are stuck with continuing resolution, many things (throughout the laboratory) could get delayed.


AARD Possibilities at NMLAARD Possibilities at NML NML Linac was described above (S.Nagaitsev’s talk) Fermilab wants to establish an AARD program at NML Flexible beam injector needed to support various beam

parameters (emittance, bunch charge, bunch length): See M.Church & P.Piot talks Tuesday AM

Unique beam parameters anticipated: Record high peak current 14kA possible ~20 um bunch length and size Beam energy upto 800 MeV Structure: 3000 bunches or witness bunch 300 um behind

Number of AARD experiments possible in NML itself: one at low energy (50MeV), one-two at full energy (space!)

APC: Accelerator Physics EducationAPC: Accelerator Physics Education The goals of APE Department:

consolidate existing accelerator education programs @ FNAL attract graduate and undergraduate students train and develop them into the accelerator scientists and

technologists who will carry our field forward in the future and enhance Fermilab’s capabilities in accelerator science and related technologies.

Four existing programs: Accelerator PhD program US Particle Accelerator School Accelerator Physics Summer Student program People Fellowship program

Joint appointments/ programs: IIT, NIU / with NIU at A0, and in RF ME

New initiative: Accelerator Education Consortium


Existing Programs (1)Existing Programs (1) Accelerator PhD Program (led by M.Syphers):

The Ph.D. Program works in a joint agreement with participated universities. Fermilab provides dedicated training for accelerator physicists at the Fermilab’s beam facilities and mentors to guide students through their research, while the students maintain relationships with their home institution's advisers who oversee the student's progress toward their degree.

US Particle Accelerator School (W.Barletta): The US Particle Accelerator School provides

educational programs in the field of beams and their associated accelerator technologies not otherwise available to the community of science and technology. The school conducts graduate and undergraduate level courses at U.S. universities, holding two such programs per year, one in June and one in January.


Existing Programs (2)Existing Programs (2) AP Summer Student Program (V.Yarba, A.Shemyakin):

The APSS program attracts graduate and undergraduate students from the US Universities and abroad to conduct accelerator research at Fermilab’s accelerators during summer months. In collaboration with US PAS and Accelerator PhD Program, the APSS program organizes accelerator physics lecture courses. The program activities are focused to attract students to join Fermilab’s Accelerator PhD programs.

In 2005 and 2006 ~10 undergraduate students in AD and TD

Peoples Fellowship Program (M.Church): The APC will co-hosts Fermilab’s Peoples Fellowship program. The goal of the Fellowship is to attract outstanding accelerator

scientists early in their careers, both to enhance FNAL’s capabilities in accelerator science and technologies, to train and develop the accelerator scientists and technologists who will carry our field forward in the future

Recent Fellows: A.Jansson (now in staff), L.Prost (just hired)

New Accelerator Education InitiativeNew Accelerator Education Initiative The situation with Accelerator PhD production, and

particularly, those entering HEP, is worrisome: future does not look sustainable

An informal task force formed to explore new possibilities: Y.K.Kim, V.Yarba, S.Nagaitsev, et.al

Under consideration now - Fermilab Accelerator Education Consortium (naturally, be part of the APC): goal is to double # of accelerator PhD students doing research at

FNAL (and staying at FNAL afterward) close involvement of local Universities:

• UChicago, NWU, NIU, IIT, UIUC – delegate faculty• Universities match Fermilab funds/efforts

be in position to select the best students, better advertising attract not only graduates, but also undergraduates extended summer student programs need more possibilities/facilities for accelerator R&D new roles for US PAS, PhD Program, AP summer program, etc.


SummarySummary Fermilab is serious about enhancing its accelerator

research program; Fermi Research Alliance initiates Accelerator Physics Center

Planning for the APC is well underway: mission, goal, responsibilities and main organizational principles are set, key personnel identified

People from AD, TD, CD and PPD will migrate to / collaborate with the Accelerator Physic Center to do: Advanced accelerator research at experimental beam facilities Beam theory and modeling Raise next generations of accelerator scientists

The APC will retain responsibility for coordination of inter-institutional collaborations in Adv.Accelerator R&D: with other National Labs, Universities, international
