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/FileName
eg:
./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...
