General Notes
- Detector Supports
- Have been redesigned/rebuilt
- Collimators
- Profile Scanner
- Connectors have been completed, will be sent to UMass
-
Compton (Tim)
- Need to recalibrate the laser polarization
- Some of the DAQ controls have been transferred to EPICS
- Will be able to revert back to old configuration if testing
is not successful
- Need to check Compton's compatability with Coil
Modulation
-
Optics Calibration (Tim)
- Is coming around
- Tough to include outside foils.
-
Lumi (Hachemi, Bob)
- Finished working on Front and Back Lumi
- BLumi shows some pedestals in the range of 2.4 to 4.9 adc channels
- A long run (2.0GBytes) shows very consistent pedestals
(signal and RMS)
- Will try changing ground capacitors (or use large
resistors) on the adapter boxes on one or more of the more
noisy channels.
- Front Lumi are ready to test
- Spare PMTs have been ordered
-
DAQ (Bryan)
- Synch Monitor connected to RHRS. Synch looks good (0 microsecond
delay, within scaler resolution).
- ADC situation for June/July looks good
- DAQ software upgrade is complete
- Still working on the Online Monitor
-
Laser Room (Lisa)
- Accelerator group took and installed the IA Cell in the Cave.
- Characterizing new PC (SAM)
- Birefringence gradient looks as good as Arwen
- Will start steering measurements today
-
Source (Kent)
- Accelerator will use SVT during May change-up
- We will be able to back-out, if it doesn't work out.
-
Imaging (Ryan)
- Meeting next week with source group to determine if an
imaging solution can be prototyped on the laser table.
- Need to make sure to order lenses soon.
