IR Magnet – BNL Collaboration $38 k in supplemental R&D allocated for FY’ 17 Focus will be on higher field magnets – looking at Nb 3 Sn as the conductor Review requirements towards JLEIC IR in FY’ 17 BNL to develop concept design of a FFQ using LARP/LHC-HL Nb 3 Sn prototype coils Also looking at modeling with 2 dipoles Timing – update discussion in late Sept/early Oct Presentation at Collaboration Concept design early calendar year Report in early spring* 12

IR Magnets Design Status 14
IR Magnets Design Status-Summary There are total 15 magnets (Dipoles and Quadrupoles) in the IR region; 2 Dipoles, 12 -Quadrupoles and 1 -permanent magnet Quadrupole. Preliminary design for 10 (out of 12) Quadrupole IR magnets has been done. Paul Brindza is looking at the Dipole Design. Peak Field in the coils, effective length of the magnet and gradient of the magnet is calculated using OPERA EM software. The design parameters listed in the table are based on the preliminary design, these designs will be further optimized. The peak field for 3 (out of 6) quadrupoles in the Ion-IR region is very high (between 11. 4 to 16. 7 T), for the other three also peak field is expected to be high. The peak field for 2 (out of 6) quadrupoles in the Electron-IR region is slightly high (around 7 T), but this need further optimization. The EM interaction between magnets QFFB 1_US, QFFB 4 e and QFFB 3 e has been looked, there is EM interaction between these magnets. This will be looked in more detail after further coil optimization. 15
IR Magnet Design – Next Steps Complete the preliminary design of rest of the 2 quadrupole magnets. Define operating current and suitable conductor Start looking at the interference/interaction between these magnets and correctors and skew quadrupoles Discuss the interference/interaction with beam line physicist Further optimization of the coil design 16
SC Magnet LDRD Probir has submitted a LDRD focused on: 6 T SC dipoles for the Ion Collider Ring Needed for 100 Ge. V center of mass energy Alternate technology solution to SF magnets for 3 T fast ramping dipoles for the Booster Ring 3 T slower ramping dipoles for the Ion Collider Ring Based on R&D Committee recommendations – insure we have backups for SF magnets Will collaborate with LBNL on LDRD UPDATE: Proposal was submitted and overview presentation presented – awaiting decision on FY’ 18 LDRD selections (early September) – not hopeful 17

IR Design Status – Mark Wiseman Met with Vasiliy Morozov and Fanglei Lin to discuss the magnet requirements. Awaiting clarifications for some of the magnets. Received the requirements for the correctors and skew quads for the Ion beam line. These have been located in the CAD model. Still have to do draft magnet designs for these. Still need electron beam corrector requirements Met with Paul Brindza, Steve Lassiter, Mike Fowler to discuss the status and coordinate the designs being worked on by all Initial coil designs, inner thermal shield and vacuum tubes have been added to some of the magnet models Discussed the beam pipe and aperture requirements with Charles Hyde, Vasiliy Morozov, Fanglei Lin and are folding this information into the design. Located one potential interference between the QFFB 1_US (Ion beam) and the QFFB 3 e (electron beam). Have not tried to solve the problem and have not discussed with the beam physicists yet. 19
