TS-SSC 90-002

From the measured coil sizes, collar size and amount of Kapton added to the standard ground wrap the expected prelodd for 050308 is 8 kpsi in the inner coil arid 11 kpsi in the outer coil. The actual prestresses are about 2 and 3 kpsi respectively. This may result from either the coil being smaller than we think it is or the collar cavity being larger than we think it is. The former would result from some as yet not understood systematic error in the coil size measurement. The latter might result from a mis-design or mis-measurement of the collars, poor tolerance on the thickness of the ground insulation or the Kapton ground insulation flowing into the die-break of the collars.

These would have different effects on the harmonics . If the coil is too small but the collar cavity is correct, the coil will require less than the expected prestress but will end up at or near the design location. If, on the other hand, the cavity is too large, the coil will occupy a larger azimuthal space than called for in the magnetic design and therefore the harmonics will be altered.

The measured body field sextupole moment of 050308 (measurements taken today by Hanft, Koska, et al using the mole) is -6 units. Gerry Morgan calculates that increasing the inner (outer) coil collaring shim by 1 mil increases the sextupole moment by 0.49 (0.41) units. That is, if both the inner and outer coil cavities are 1 mil smaller than the design value, b2 wil I be +0.9 units. To generate -6 units would require the inner and outer cavities to be 7 mils too large (assuming an equal error in both).

I put such a collar size error into the spread sheet that is supposed to calculate prestresses from coil sizes. Lo and behold, the predicted prestresses are 2 and 3 kpsi on the inner and outer coils. On the final collaring of 050307 the measured prestresses are about 5 and 7 kpsi in the inner and outer coils while the predicted prestresses are 11 and 13 kpsi. If I increase the collar cavity by the same 7 mils, the predicted prestresses drop to Sand 5 kpsi.

The closeness of the agreement between calculation and measurement is probably somewhat fortuitous given all the fine points that I have ignored in this argument. Nonetheless, it suggests that the coil size measurements are more or less correct and that the collar cavity is to blame for the low preload. Stuffing more Kapton at the poles of 050309 will probably not only increase the preload but also set the harmonics to the correct value.

MEMORANDUM

To: R. Briggs and T. Bush

From: R.B. Palmer

Date: March 26, 1990

Superconducting Super Collider Laboratory 2550 Bedky~ade Avenue, Suite 220

Dallas, TX 75237·3946

Subject: MAGNET TASK FORCE, INTERIM REPORT #3

This report reflects discussion of the Task Force at its meeting on 3{21/90, held at SSCL, and other discussions.

Modification to preyjous recommendatjop

The recommendation (1) in report #l on the od yoke (13 in.) should be modified to define the OD of the shell. The OD of the shell should be 13-3/8 in. or 340 mm.

Recommendations;

1) the ratio of copper to superconductor for the cables should be:

inner: 1.5: 1 outer: 1.7:1

These choices give: short sample field, field margin, and copper current densities at 6.6 and 7 .2 Tesla of:

inner: 7 .26 T 10% 712 A/mm sq

outer: 7.46T 13% 866A/mm sq

782A/mmsq

953Nmmsq

The copper current densities in the outer cable are higher than some of us would like, but the obsel"Ved rarity of training quench in the outer layer, in current SSC magnets, suggests that this should not be a problem.

In addition, the development of an ·outer cable with ratio of 2.0 : 1 (which would have matched the margins in inner and outer layers) was considered to be a significant task, and not worth the possible small improvement in fll'St quench field

Page 16: TS-SSC 90-002 FNAL::JBS 28-MAR-1990 22:31:00.77 …lss.fnal.gov/archive/other/ssc_notes/TS-SSC-90-002.pdf · 2013-03-15 · TS-SSC 90-002 From the measured coil sizes, collar size

'• .~ .

The cost savings in further raising the copper ratio (eg about S m$ for a change from 1.5: 1 to 1.7: 1) were not considered to be worth the loss in field margin.

Note that this field margin of 10% will probably be reduced by subsequent decisions (see, for instance, recommendation #3).

2) An intermediate temperature Beam Tube Liner should be inserted within the bore of the magnet Cooling, at around 20 degrees. should have the potential capacity of removing at least 10 times the present design synchrotron radiation loss.

Such a liner will allow future upgrades of machine luminosity, by allowing an order of magnitude higher currents.

Such a liner will also allow operation of the magnets at lower than design temperature, this increasing either the operating field or operating margin.

If such a liner is not designed in at this time, it will be either impossible, or very expensive to retrofit it later.

A study of the design of lhi:s bore tube liner should be initiated, at once, jointly by the magnet and accelerator departments.

3) The quadrupole aperture should be raised to S cm

The change will make it possible to insert, within the bore of the quadrupoles (as is now possible in the dipoles), the intermediate temperature beam tube liner.

It will reduce the contributions to field errors from the quadrupoles and make the contribution per meter, or per magnet end, approximately the same as those from the dipoles. Note that the effects on aperture, per meter, or per magnet end, will still be greater for the quadrupoles than for the dipoles, because the beta functions are at their maxima in the quads.

The change will ease the possible problems in winding the pole turns with the wide cable.

The change will make the tooling radii the same for quadrupoles and dipoles. It will also ease the design of interconnects between quadrupoles and dipoles.

4) The new quadrupole design should use the same cable as specified for the outer layer of the dipole. The iron yoke should be allowed to come relatively close to the coil, in order to maximize the gradient and match; as nearly as possible, the droop in the transfer function of the dipole. The field margin should not be less than that in the dipole inner (now 10%) at operating energy.

It is recognized that the resulting quadrupole will have a somewhat lower gradient than that of the present 4 cm design. It will, as a result, have to be somewhat longer. The dipoles will have to be a little (perhaps of the order of 1 % ) shorter, and will have to operate at a sightly higher field. This, in view of the current design field margin, seems reasonable.

5) A priority engineering study is needed on the vertically split yoke design. In order to specify the shell thickness, and thus yoke outside diameter, the loss of stress in the shell during cool down must be calculated. The differential coefficients of expansion and the changing yield strength of the aluminum must be tracked with temperature, and, the effects of friction between the shell and yoke must be included. It might be useful to construct and instrumented short section to observe the behavior of this design.

It is recognized that calculations on the fast track horizontal split yoke must have the highest priority, in as far as they may effect the yoke or collar specifications. But studies on that design, beyond those required for the specification, should give way to those needed for the vertically split yoke.\

6) For the moment, all S cm magnets should use kapton and epoxy fiberglass insulation (the standard insulation).

Nevertheless, the BNL studies of alternatives should be continued, and FNAL should try, within reason, to make their tooling capable of using them.

7) In order to allow continuing study of alternatives (all kapton insulation, aluminum bar yoke, aluminum collars etc.), and to have a real horizontally split yoke, BNL end, backup design; the BNL program should be expanded to include full length 5 cm magnets.

The FNAL program will be hard pressed to produce the required magnets for the string test, and does not have the capability to simultaneously pursue possible serious improvements.

If the alternatives are not pursued actively, and with full length magnets, it will not be possible to incorporated them without significant later delay. To try and pursue these alternatives only in industry, or at SSCL, will be too late, and will lack the BNL experience.

If problems should arise in the FNAL magnets, due to any of the changes that they are introducing, a serious delay will be introduced wtless we have a real, and tested, backup. For FNAL not to adopt these changes, because there is no backup, would mean accepting serious compromises.

We need, and will continue to need, all the expertise we can get. The BNL group has built all the currently tested full length 4 cm coils and associated yokes. They have their 5 cm work to short magnets will greatly reduce their overall involvement and commitment, and limit our access to their expertise.

Recommended Studies

1) Study of the aluminum collar, aluminum bar, vertically split iron yoke, should continue with relatively high priority. This is a very attractive possibility, but will have to be rapidly developed if it is to be available for use in time. The magnetic design of the yoke is being studied at BNL. If a reasonable solution is found, then a stress analysis should be done as soon as possible. This has less priority than that needed for the BNL or FNAL track specifications, but a higher priority than analysis of those designs, after they are specified.

2)Studies (already in progress at BNL and LBL) of alternative methods of correcting the saturation sextupole (with holes, shims. elliptical or other yoke shapes should also continue).

3) Study of the fishbone an and quench venting problem should continue, but this does not now seem to be a high priority question.

4) Studies should also continue of alternative coil arrangements to lower peak fields, simplify construction, and have wedge in the inner layer opposite the pole shim of the outer layer. But these too can continue with relatively low priority. They can be incorporated with little penurbation at a later time.
