Notes from Local Meeting Sept. 24, 2003

General Updates

• Accelerator will be down for 1-2 months because the power outage due to Hurricane Isabel caused the He to boil off and the superconducting cavities to warm up.
• HAPPEX is still being considered for April (actually later due to accel. delay) if G0/Hypernuclear run at the same time. This will be Hydrogen running and possibly some He.
• SAMPLE has new result consistent with theory to give more accurate measurement of magnetic moment of the strangeness of the proton.

Individual Updates

• Bryan

  • Working on superGUI
  • Working with readout of HAPPEX detector PMTs by ADCs

• Kent

  • New student from Syracuse is coming. He will probably work on Lumi, panam, and polarimetry
  • Reported on results of Septum heating test. Further testing needs to be done, but HAPPEX runs the risk of running very close to the septum quench point.
  • Cooling for septum is being improved by clamping copper to bore tube.
  • Will work on GEANT septum heating simulation with Eugene's help

• Lisa

  • Tried to characterize TX cell from Cleveland Crystals but realized that the switch we have in the laser room won't work with this cell. Will resume work when we have a bipolar switch available.
  • Began to align new Lasermetrics cell for characterization study.

• Ryan

  • Working in the laser room
  • Getting ready to start analyzing saGDH data for A_Q and position difference values.

• David

  • Working on/will work on radiation budget issue for HAPPEx-He

• Eugene

  • Working on geometry for GEANT septum heating simulation.
