Talk:GTS meeting 6 27 16

• Things to try next, in order:
• 1. Run with the beam viewers shields completely out for improved pumping speed,
• 2. Bias anode positive, John hsa PS
• 3. Increase laser spot size to 4 mm
• 4. Make a brand new photocathode (there is one puck with bare GaAs in the prep chamber) using the mask.
• For future, Joe G. recommends to do a high temp (450) beam dump bakeout.

• And also:
  • QE scanner, Dennis Turner working on software, Shukui and Adriana to setup laser scanner beam alignment
  • We need full EPICS control of the laser....some day
