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 60 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 70 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 not usually be triggering on HMS or SHMS singles. Adjust prescale to give a very small number. We will have some EDT triggers (10 Hz)
- Prescale: PS5 0 all the time.
Optics studies
- Series of optics calibrations runs at various central momentum of the HMS and SHMS
- Cycle magnets if needed.
- Run with sieve IN, raster 2x2,optics #1 target and highest current reasonably possible.
- Want to take electron singles triggers.
- Constant HMS/SHMS Conditions:
| HMS/SHMS collimator: | SIEVE, CENTERED SIEVE |
|---|---|
| HMS/SHMS trigger prescales: | PS1:-1 PS2:1 PS3:1 PS4:-1 PS5:-1 PS6:-1 |
| HMS angle/momentum | 13.5 deg, -6.358 GeV/c (First momentum setting) |
| SHMS angle/momentum | 13.5 deg, -6.358 GeV/c (First momentum setting) |
| Raster size | 2x2mm |
| Target | Optics #1 (3 foils at 0cm,+/-10cm) |
| Current | Max current that can be achieved |
- Momentum settings:
| Run 1 HMS/SHMS momentum: | -6.358 GeV/c | Record 100K electrons in each arm. |
|---|---|---|
| Run 2 HMS/SHMS momentum: | -5.983 GeV/c | Record 100K electrons in each arm. |
| Run 3 HMS/SHMS momentum: | -5.714 GeV/c | Record 100K electrons in each arm. |
| Run 4 HMS/SHMS momentum: | -5.270 GeV/c | Record 100K electrons in each arm. |

HMS settings: p=--5.27 GeV, theta = 16.3 HMS polarity: negative SHMS settings: p=- 3.44 GeV, theta = 16.0 SHMS polarity: positive
Put in LD2 target Run for 30 minutes at 45 muA Run for 40 minutes at 30 muA Run for 60 minutes at 15 muA Run for 30 minutes at 60 muA Run for 30 minutes at 70 muA (if available)
Change polarity of SHMS to -3.44 GeV (negative) Run for 30 minutes at 45 muA Run for 40 minutes at 30 muA Run for 60 minutes at 15 muA Run for 30 minutes at 60 muA Run for 30 minutes at 70 muA (if available)
If have time still, repeat this program with LH2 (start with SHMS negative this time)
If still have time, change to dummy target and Run for 30 minutes at 40 muA SHMS positive polarity Run for 60 minutes at 15 muA Run for 30 minutes at 40 muA SHMS negative polarity Run for 60 minutes at 15 muA

# 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).
