adaql2 - DAQ
Never run any application on adaql2 except DAQ, even using ssh to other computers
- CODA runcontrol
-
- Configure, Download, Start, End run (kcoda, startcoda)
- Select the GEN configuration
- Watch download process
- Watch the ROCs
- Check the event rate (~600 Hz at 8 µA with ³He target)
- Check the correspondence of run numbers in the datamon(DMON) and in the CODA runcontrol
- Watch the dead time (~12-15% at 8 µA with ³He target)
- Check prescale values (100000,80,1 for production).
- After you start new run with GEN DAQ
- Start a new run with HAPPEX DAQ on adaql1
- Check raster size with spot++ on adaql1
- Check the charge asymmetry with qasy on adaql1
- Check detectors with onlineGUI
- Thresholds
-
- Check thresholds ( 0: -320, 1: -25, 2: -145 for production)
- ROCs
-
- Check terminals connected to ROCs.
- How to reboot, troubleshoot and check ROC status?
adaql1 - DAQ
- HAPPEX DAQ
-
- Configure, Download, Start, End run (kcoda, startcoda)
- Watch download process
