Current Status

  • Tuesday was maintenance day, hall was locked back up around 3 p.m.
    • Larry/Jerry pumped on SHMS transfer lines for a few hours
    • Heidi did some checks with thermal camera
  • Hall Access around 8:40 p.m. to reset a Solid power supply
  • Beam returned around 1 a.m. after maintenance day
  • Finished Settings 9/10 on HMS
  • Taking positron data with HMS, electron data with SHMS
    • The Runplan gets FUN now

Run Plan (selected)

  • Positron running on 48Ca at 35degrees with HMS
  • 20 degree HMS positron data taking at larger x
    • ALL targets on the ladder!
  • HMS hydrogen elastic data for momentum offset (back in electron mode)
  • Rate/tracking study with LD2 target (HMS at 35 deg, SHMS still at 8 degrees)
  • Boiling/Luminosity study (higher current, additional points - Thursday, Nov 17)
    • Rotate both spectrometers and change momentum
  • EMC data on Ca48 with HMS at 35 degrees (several HMS momentum settings)

Issues

  • Current Limited


Notes

  • After Thursday's boiling study, our beam authorization will be changed to 60uA (ish)
  • The shifts will be fairly active:
    • Spectrometer Rotations
    • Momentum Changes
    • Target changes
    • Diffent KINDS of data being taken
