Overview

The beamtime aims to perform timing scans for the 2M.0 detector. Scans will be taken in FL, FM, and AML; two fluxes in each gain mode, and likely an intensity scan at a couple of timings once we have checked the results of the timing scans. The experiment the data will land in is xcsc00121.

Daq script

Timing scans for the 2M are performed from Philips setup:

~philiph/psana/Workarea/daq/daq-dev/tools/scanning/epix10ka2M_scan_exponential -L yes -e 100 --start 50000 -f 80000 -n 26 -P AcqToAsicR0Delay -p 0 -D XcsEndstation -t 2 -i 0

Analysis scripts:

You can find it here: /sdf/data/lcls/ds/mfx/mfxx1005021/results/scripts

You can call it with: >python -i TimeScan.py -d Epix10ka -r 472

Results:

Timing scan at different fluxes AML:

Fig 2. AML, rough scan, 80% beam.

Fig 3. Fine scans at rising edge, aML 80% beam. The time delay between quads is apparent.

Timing scans FM high and low flux:

Timing scans FM high and low flux:
