RC Meeting, Thursday, August 23

• General
  • Beamline vacuum still not great
  • BCMs at 3H04 now at 110 deg. thanks to after hours sleuthing by Dave M.
  • Beam likely not ready to send to hall until Friday
  • LN2 vendor has supply issues - JLab usually gets 2 trucks/day - vendor can only provide 1 truck/day. Alternate supplies under investigation.
  • Dave Mack added some attenuation to BCM4a so it won't saturate at ~ 70 uA

• Target
  • Target warmed up due to LN2 issue
  • Target cooldown??

• SHMS
  • After beampipe adjusted, SHMS rotated to 5.69 degrees, but SHMS touched beampipe
  • Minimum safe angle will be 6 degrees
  • Remote motion control allowed down to 7 degrees - for angles below 7 degrees, all motion will be disabled once set (this includes HMS!). Any rotation after will require access
  • SHMS is set to 6 degrees in preparation for beam steering test

• HMS
  • After beampipe adjusted, and some modification to cable conduit, able to rotate to about 10.9 degrees. Minimum angle will be 11 degrees. Remote motion allowed down to 12.75 degrees

• • Minimum separation between SHMS and HMS 21.5 degrees

• DAQ
