5 pass Run Plan
From HallCWiki
5-pass run plan
Goal
The goal of the E12-09-017 experiment is to measure the pt-dependence of SIDIS from proton, deuteron, and aluminum targets, for final state pi+, pi-, K+, and K-. The experiments aims to measure absolute cross sections with particular attention to achieving small errors on the ratios of cross sections for different final states and targets. The beam single-spin asymmetry will also be measured at the settings with sufficient phi coverage. The specific goals of this 5-pass run plan are: a) take the missing 6.5 degree setting for kinematic groups 1-8 that were taken in Spring 20187; b) do a higher (x,Q2) setting with kinematic groups 13-16.
Experimental setup
- Main trigger is 3/4 hodoscopes in HMS in coincidence with 3/4 Hodoscopes in SHMS.
- HMS is setup for detecting electrons (inclusive DIS measurement).
- SHMS is setup for detecting charged pions and kaons (semi-inclusive DIS measurement).
Settings to monitor during shift
- Beam energy: 10.6 GeV. Raster 2x2
- Beam current:
- The nominal beam current is 40 muA. Please adjust the actual beam current to give the single SHMS rates below 500 kHz each time you change targets. You can see this number under "Ptrig1" on the upper left side of the scaler GUI. You can go as high as 60 muA for LD2 and LH2 if the rates are low enough. The dummy target is limited to 40 muA. Approximate beam currents (good starting point) are in the tables below.
- Trigger:
- Main trigger is EL_REAL in HMS in coincidence with 3/4 Hodo in SHMS (same as for Kaon-LT experiment).
- We will also trigger on HMS singles with a pre-scale factor. Adjust prescale to give about 50 Hz. Also adjust prescale to give about 50 Hz SHMS triggers. We will also have some EDT triggers (10 Hz)
- Prescale: PS6 0 all the time.
Kinematic Settings
# means setting number Ptrig6 is the approximate anticipated coincidence rate divided by 3 in Hz approximate current current is the current for which rates are calculated (on LH2). It is fine to run at higher currents (preferably around 60 uA), except of course on the dummy target (40 uA).
