Luminosity scans on LH2 and z=1.5% RL C targets.
Goal
The electrons in the HMS will be used to monitor cryotarget boiling, while the positive polarity SHMS will be used to investigate the reliability of hadron tracking efficiencies at high rates. We will use three different targets:
- standard 10cm LH2
- C (z=1.5% RL) - maximum current 65uA
- Al dummy - maximum current 40uA
Initial Setup
- Set PS1 and PS3 DAQ rates to 1.5kHz, to give a total rate to disk of about 3kHz.
- Increase EDTM trigger rate to 10kHz, to ensure that after prescaling there are 10k-100k EDTM events per run.
- Ensure the raster is on (2x2)
During scan
- Monitor number of EDTM events per run carefully to ensure 10k-100k events/run.
- Try to get runs with minimum of beam trips
