Run settings p+Pb @ 80GeV/c |
|
|
Target: Lead 5 mm
Beam: protons
Beam momentum: 80 GeV/c
Beamline settings:
http://na61-elog.cern.ch/Beam+logbook/181
Beam vertical counters position:
V0: 56.9 mm
V1: 82.0 mm
S1: aligned by geometers
S2: 84.5 mm
S4 horizontal posotion: 14 mm to Jura side, detector in the beam with full magnetic field
S5 position: out of the beam (h: -400, v: 16.9)
Thresholds:
V0: -130 mV
V1: -518 mV
S1: -158 mV
S2: -153 mV
S4: -338 mV
S5: -289 mV
Trigger:
There was problem with pattern units copying. Runs 23134 - 23183 can do not have trigger pattern units copied to raw/shoe files (!)
Trigger file in use:
15/07-18/07 : 2016_test_pPb_80Gev.cnf
since 18/07 : config-14688126241557.cnf
Trigger settings:
T1 = S1*S2*V0bar*V1bar*Ced6
T2 = S1*S2*S4bar*V0bar*V1bar*Ced6
T3 = S1*S2*V0bar*V1bar
T4 = S1*S2*S4bar*V0bar*V1bar
Trigger scaler factors:
T1 = 200
T2 = 1
T3 = 4095
T4 = 4095
HV settings:
https://na61-elog.cern.ch/Experts+logbook/263
S4 HV: +2200 V
Magnets ON - field corresponding to beam momentum
Vxt 1 - 2397.7 A
Vxt 2 - 1835.6 A
PSD:
within runs 23134 - 23237 there were 2 PSD trigger scintillators in "beam 0" (not in the beam!!) position
within runs 23142 - 23161 mod#12 has faulty FPGA channels
PSD position:
Z at 20.5m from target
platform X = 660 (5cm shift down)
platform Y = 960 (25cm shift to Jura)
NOTE: During all data taking there was "small module" in front of modules 21 and 22!
TOF:
ToF-R: worked in production runs
ToF-L:
- within runs 23134 - 23197 partially worked (64 dead pixels due to bad TDC)
- within runs 23198 - 23206 partially worked (17 dead pixels due to missing trigger cable connection)
- since 23207 seems to be working |
