• Other

PARTICIPANTS: Amy Comer, Arshak Asaturyan, Bogdan Wojtsekhowski, Donal Day, Rolf Ent, Hamlet Mkrtchyan, Marie Boer, Petr Stepanov, Tanja Horn, Tristan Anderson, Vardan Tadevosyan

DESIGN/ENGINEERING (Steven, Amy, Bogdan)

• Copper absorber prototype modeling and FEA ongoing

• initial results of the simulations summarized in ppt slides - checking different scenarios
• some details need to be further investigated, but overall looks promising

• Quote requests for the copper absorber have been sent out to vendors

• Fluent model - good progress

• Bert has been working on updating the coils and magnets to the longer lengths

• Waiting for response from Elmet before making decision on how to proceed with Tungsten blocks

• bids are coming higher than estimated, so far no information received from Elmet

• Additional lead bricks will be available from MIT-Bates

• Gabriel will check optimal position of tungsten/lead with simulation

TRANSVERSE TARGET MAGNET UPDATE

• From Chris K.: Scientific Magnetics is making good progress

• coils are assembled and quench protection circuitry is in place - will be wired next week
• Vacuum chamber and cryocooler are assembled and have been successfully tested (no leaks, pulse tube reached <4K, etc.)
• Magnet will be installed in the cryostat in September
• A few cooldowns are expected to optimize placement of shims and to reach the required field uniformity

• Action: ask Chris K for update on shims, field uniformity, etc. sometime in September

TCS TRACKING UPDATE (Vardan)

• Investigated backtracking to account for deviations from linear regression

• Both methods of tracking give very similar results - backtracking works a little better, dependend on momentum

• Need to check on magnetic field sign outside target

NEXT MEETING: FRIDAY 24 SEPTEMBER AT 8AM ET
