Progress on MICE Coupling Solenoid Magnet
Progress• The inner coil radius was changed from 744 mm to 750 mm to allow
more space between the coil inner side and the inner vacuum chamber.
The engineering design was updated accordingly.
• The coil winding system is under construction with the funds from HIT.
• The prototype coils were designed.
• The formal collaboration MOU between LBNL & HIT was developed and
signed by both last June. The formal Addendum to the MOU between
LBNL and HIT, and the Technical Agreement for the MICE/MUCOOL
coupling magnets was developed and signed in September.
• The formal proposal for MICE project to the Ministry of Science and
Technology of China was submitted by HIT at the end of this June with
SOA and MOU from MICE collaboration and LBNL.

Progress on MICE Coupling Solenoid Magnet
Stress analyses on the vacuum vessel and cold mass supports were completed.
Improvement on quench protection programming with quench back, and optimization of the quench protection circuit design are underway.
The fabrication plan (e.g. winding procedure and tooling, and assembly procedure and tooling etc.) is further detailed.
For coil assembly, study on effects of coil winding tension, banding applied to the outer surface of the coil and the possible inclusion of slip planes at the insulation interfaces to the mandrel are being carried out. 2-D simulations on effects of slip planes at the insulation interfaces to the mandrel in the coil assembly were completed. 3-D simulations on effects of coil winding tension and banding applied to the outer surface of the coil is almost done.
Test for thermal properties of AIN and contact resistance among AIN, indium film and cooler cold head by PTR-407 in ICST is under way. The test station was designed, built and under commissioning.
• The engineering design on the coupling magnet has been further updated
and detailed.

Comparisons
The self inductance of the coil increases from 564 H to 593 H (~5%) ,
and the magnet stored energy increases about 4% with the coil inner
radius increasing from 744 mm to 750 mm.
The peak induction in the coil and the temperature margin dropped by
a small amount.
The space between the cold mass and the inner thermal shield
increased from 9.7 mm to 15 mm, which will be helpful in reducing the
heat load at 4.2K.

Progress on MICE Coupling Solenoid Magnet
Comments
The thermal stress still dominates as compared to the magnetic coil forces
During cool down from 300K to 4.2K, the coil center moves inward about 2.9 mm.
When powered to 210 A, the coil center moves outward about 0.9 mm
Most stress in the coil is less than 40 MPa due to thermal contraction and increases
when powered. The peak stress is about 94 MPa in the corners and where the peak
field is located
The maximum stress due to cool down in the Al coil case is at the corners (92 MPa)
and increases to 142 MPa when powered, which is less than the allowable stress of
6061T6 Al at 4.2K (~161 MPa)
The hot spot appears at the high field point in the coil winding for normal operation,
and the ΔT of 0.082K is acceptable
Due to the reduced thickness of Al banding, the ΔT between the hot spot in the coil
and the cooling helium decreases (even though the AC losses increase for the larger
diameter coil)
The stress & deflection in the coil and the AC losses changed only slightly.

Comments
The maximum field on the coupling coil is 7.40T for the 240MeV/c
flip mode (7.44T for 744mm IR coil), which is on the inner surface
of the coil.
The influence of magnetic field on the coupling coil from other
coils in the channel is not much (within 2 percent).
The effects of stray magnetic fields on the HTS leads and
cryocoolers are nearly unchanged for the 750 mm coil design
compared with the 744 mm coil.

Comments for Coil I at 210A
The magnetic induction in the center of small coil is about 2.27T.
The peak magnetic induction on the small coil’s inner surface is about 2.8T
The maximum stress is in the banding (75.2 MPa), which is within the
strength limit of Al 6061-T6
With 2-sectioned and 0 resistor, the hot spot temperature is about 65K,
and the peak internal voltage is about 135V
Comments for Coil II at 210A
The magnetic induction in the center of prototype coil is about 0.65T
The peak magnetic induction in the coil’s inner surface is about 3.91T
The maximum stress is in the banding (93.9 MPa), which is within the
strength limit of Al 6061-T6
With 4-sectioned and 0 resistor, the hot spot temperature is about 65K,
and the peak internal voltage is about 135V
