Revision as of 18:05, 11 February 2015
Listed in order of suggested priority...
Re-measure emittance in order to analyze Run 1 conditions (3 hours)
- February 9, 2015:
- Identified parameters and details for a procedure
- Measured emittance and Twiss for 6.3 MeV/c setup
- Started emittance and Twiss for 5.5 MeV/c but harp is stuck so test deferred for now
Test hardware TOF veto at 31MHz (4 hours)
- Runs 8210 - 8217 with 0.225 um gold foil
Test FADC time-of-flight readout (1 hour)
- February 4, 2015:
- Added two more laser timing signals to FADC. From Disc 708, OUT signal was connected to FADC Ch10 and OUT_bar was connected to Ch12. The original laser timing signal is still connected to Ch9.
- Run 8224 with 1.0 um gold foil and Mott_SemiInt configuration
Test background as a function of target ladder position on large target foil (0 hours)
- February 9, 2015:
- Deferred until re-doing emittance measurement at 5.5 MeV/c to try for smaller spot size with 5 or 10 mm rings too
Test Mott delayed operation (1 hour):
- Set of 6 runs while changing between No Delay and Delay=8
- Runs 8218 - 8223 with 1.0 um gold foil
- media:Delayed_Ana.pdf media:Delayed_Ana.pptx
Test new Mott DAQ Configurations (1 hour)
- Measure deadtime with 2.2 uA on 1 um gold foil:
- Run 8225: Mott_SemiInt configuration (FADC+TDC+Scalers), Deadtime = 28% at 5.1 kHz.
- Run 8227: SemiIntFast configuration (only readout of FADC, Blocklevel = 1) , Deadtime = 17% at 5.1 kHz.
- Run 8228: SemiIntBlock configuration (only readout of FADC, Blocklevel = 50) , Deadtime = 1% at 5.1 kHz.
