From Joe, here is the latest on the AIPINJ magnets (priorities #5, #4, #2, #3, #1)

• FX & FY solenoids (Everson Tesla): Mike QC’d the last shipment of magnets and spare coils. They passed and we have accepted all 10 solenoids and 4 coils. All ETI measurement data is within the +/-5 G-cm requirement. Will send out to Jay and Lakshmi. Invoices have been approved and paid. The tooling was also shipped and can be stored with us if needed.
• DR dipole (Milhous): The 2nd half of the first article is being wound. ETA is next week. Will look to put on measurement stand ASAP.
• HD (Technicoil): Stainless bobbins completed. Starting winding. On schedule to be finished by 10/23.
• QW (Technicoil); No updates; will follow-up with Technicoil.
• Wien Dipole (Carlos): Wien cores delivered to MMF shop. Mike will start the coil fit-up process with coils and vacuum chamber next week (10/19-10/23). Mike performs final assembly and measurements first two weeks of Nov. (11/3-11/13).

PSS kicker

• Lakshmi completing analysis (due latest Monday) on PSS kicker using 3 types of conductor (reason for add'l work is long lead time availability of Plan A wire)
