Notes from Local Meeting on April 1, 2004

In attendance: David Armstrong, Hachemi Benaoum, Rob Feuerbach, Lisa Kaufman, Kent Paschke, Ryan Snyder

Rob reports talking to Dave Meekins concerning choices of solid targets for HAPPEX. The ladder has space for 5 solid targets. Those will be "empty", BeO viewer, Lead, Single Carbon, and one other, probably either a Titanium Hydride powder in an Aluminum vessel or a Kapton foil. It was hoped to have both a TiH and Kapton target, but it appears that one or the other must be chosen, with the most important criteria being the probably of surviving long enough to make a useful measurement.

Attended recent Cryogenics review. The CHL will be providing additional He coolent directly to Hall A (as opposed to simply bolstering the ESR) in order to run the high-power cryotargets.

A cryo incident in Hall A that would previously have brought down the ESR can now potentially bring down the CHL as well!
They are very concerned that target operators be properly trained, to the extent that they may ask to assist or supervise training of the Hall A cryo operators.

Regarding the Helium experiment radiation budget: met with Pavel. Rates are continuously monitored around the experimental area and at the site boundry, with values displayable (and logged) via EPICS. No special arrangments will be necessary to monitor these rates for the HAPPEX-He test run.

Ryan
- Showed a possible imaging solution. More thinking to be done, but there look to be some possible solutions that will accomplish what we want

HAPPEX "analysis logbook" (based on PSI ELog) in use, linked from HAPPEX webpage.
Fixed soldering on one of the HAPPEX ADCs. 1-2 spare ADCs will be available during the run.
The Sync monitor is being added to the R-HRS DAQ.
Work continuing to modify the online GUI to monitor online rootfiles (replace PANAM)
