Announcements
- Mailing list launched => aipinj@jlab.org
- Latest layout update Friday Feb 10
Tally components by systems
Correctors (21 pairs , down from 23 pairs)
-Will re-use existing MBH (long Haimson), MHB (short Haimson), MHD (on A1 cube), and eliminate MAD in favor of another type -Total number of H/V pairs is 21 (goes down by 2 pair, so should free up 4 channels)
Dipoles (2: same number)
-PO written for two new 15 deg dipole fits on 3" OD pipe (replaces existing similar MDS fits on 2.5" pipe) -500 keV spectrometer dipole (MBO) will either be re-used as-is, possibly modified for taller vacuum chamber aperture
Solenoids (11: same number)
-Gun to Chopper region : retain two FG solenoids + upgrade the FH, FB, FQ with three new FX solenoids -Chopper : retain two FA solenoids captured to chopper cavities + upgrade the two FD solenoids with two new FY solenoids (TBD: one or two PS) -Chopper to Booster : upgrade FA, FL with two new FX solenoids
Quadrupoles (6: same number)
-Replace existing 6 quads (types QW, QU) with two new triplets (3Q), under design now -If design is late or does not come to fruition, may retain the 6 quads we have now -Right now, retain one skew quad MQS0I07, but should be eliminated by improved Booster module
Earth Coils (2: same number)
-One coil across chopper -One coil across chopper-booster
Bullets from last meeting...
- New 200kV small shed cathode electrode at machine shop (like electron at UITF)
- New gun 10" anode flange being designed to locate a steering coil closer to the gun
- Phil/Marcy starting to NEG coat vacuum chambers; need a 1kW sputtering PS that works (1 kV, 1 mA)
- PO for 200 kV injector solenoids written (delivery April - June)
- Shaun designed alignment fixture for new beam line solenoids
- PO for 200 kV Wien magnet coils written (delivery March)
- Success applying +/- 20kV to UITF Wien! Testing w/ better vacuum comes next...
- PO to be written for new 15 deg dipole next week
- Chase assigning new names for dipole and solenoids
- Starting to study which laser vacuum window to use 2-3/4" as-is, or 4-1/2"
- Curt waiting on kV spec for prebuncher @ 200 kV, for Watt in S.S. cavity
- Reza/Alicia/Dennis evaluating re-ordering of layout
- Looking at installing valve downstream of chopper #2 this down, possibly during fc#1 repair
- Gary Cheng inquiring about checking cryo lines between QCM and Booster
- 5D beam line will be removed
- Neil/Anthony working plan to build table to move QCM/Booster
ATLIS Tasks
AIPINJ
Non-AIPINJ
- New Gun2 loading chamber
- Placeholder for Tim Minga to test laser room smoke detector alarm to MCC/Guard
