RunPlan20150722¶
Tracker Timing studies¶
Note.. I'll insert instructions and beam requests here.
Please use the following standard pion reference beam (and check this is the std. reference beam):
| Particle Species | p at Tgt | p@D1 | p@D2 | Proton Absorber | Q1 | Q2 | Q3 | D1 | DS | D2 | Q4 | Q5 | Q6 | Q7 | Q8 | Q9 | Similar Run(s) |
| mm | A | A | A | A | A | A | A | A | A | A | A | A | A | A | A | A | DAQ run # |
| Pion Reference | ? | ? | ? | 29 | 57.8 | 105.7 | 64.5 | 202.8 | --- | 176.9 | 237.1 | 157.2 | 157.6 | 238.5 | 125.70 | 203.7 | 7257 |
I would like the following runs:
Target is 25K Triggers in TOF1 per run...
| Run Type | Timing FileName | Efficiency | Alive Window | Alive Window | Est. | Run # |
| (Trig/Request) | Delay (ns) | Width (ns) | Spills | |||
| Nominal | Nominal.cfg | 0.8 | 130 | 110 (116.4 meas.) | 1400 (20min) | ?? |
| Section1 | Timing_section1.cfg | <0.2 | 130 | 30 (35 meas.) | 5600 (2hr) | ?? |
| Section2 | Timing_section2.cfg | >0.2 | 130 | 30 (30 meas.) | 5600 (2hr) | ?? |
| Section3 | Timing_section3.cfg | >0.2 | 130 | 30 (35 meas.) | 5600 (2hr) | ?? |
| Section4 | Timing_section4.cfg | <0.2 | 130 | 30 (35 meas.) | 5600 (2hr) | ?? |
Instructions:
Cd into directory on acq machine:
ssh miceacq16 cd ~/tracker/gate_generator_config/
For each setting do the following Run:
./ConfigDownloadT560.py timing_studies/FileNameeg:
./ConfigDownloadT560.py timing_studies/Timing_section1.cfg
Once complete run to restore to normal beam settings:
./ConfigDownloadT560.py BeamTiming_TOF1.cfg
Notes: In run 7257 830 spills collected. Assume ~1 noise hit in TOF2/TOF1 per spill = 830 noise hits
TOF2/TOF1 scalars: 4835/19737 = 25%
TOF2/TOF1 = 20%
23 Triggers per spill.
Would like ~5K hits in TOF2 for each setting. => 25K Particle Triggers in TOF1.
Could Halve these values if needed...
