Quick start instructions

1. Always run the 50k replays!
2. Each setting has count goal to be reached, e.g., "20000/ 276". This means 20000 "good coin events" (see next item) need to be counted. The charge, 276 mC, is just an estimate.
3. The counts for a given replay are obtained by (see below for more details):

   If not already on cdaql1 -> ssh cdaql1
   bash_csv replay # will setup environment
   do_good_coin -c 20000  # will run the counter on the latest run
   

Note: Running this script will update the "Charge Goal" field on the "blue screen". Follow this charge goal to determine when a setting is complete. The full analysis takes some time, so the number of counts reflected in the "make_csv_runtable" command will not be accurate until the full analysis is complete.

Open web browser to online counter plots

1. Files to update:

   DBASE/COIN/standard.kinematics --> This is now updated automatically. If the online plots come up blank, check that the file has updated appropriately.

   Keep current before running any replays

2. Update the tables in the wiki:
   1. Add good coin counts in "actual"
   2. Set the correct run (or range of runs) under "Runs"
3. Go to Information_for_Shift_Takers

More Details

Setup

ssh cdaql1       # connects to cdaql1
bash_csv replay # puts you in the correct directory

Blue screen (charge monitor)

blue_status_screen

The following is for experts only:

To reset the "Kinematic Setting" counter (if it did not reset at the start of a new run setting automatically). Do not do this if you have not yet started a new run.

caput hcRunSettingReconfigured 1

The counter will reset with the next run start.

To get the current run's charge and time:

caget hcCOINRunAccumulatedCharge
caget hcCOINRunTime             

To set the accumulated charge and time for setting:

caput hcRunSettingAccumulatedCharge  CHARGE_IN_uC
caput hcRunSettingTime               SECONDS

Look at the latest results

Connect to plot display server (only works from counting house computers)

• The various plots are created when the full replay and counting scripts are finished.

Full replays

The full replay automatically starts about 3 minutes after a run start.

To see the currently replays in-progress:

./online_bin/auto_replay_stat

monitoring full replays

Looking at the logs (all replays)

mux logs

To attach to the tmux pane running the replay for a run, run the following command.

./online_bin/auto_replay_stat -r RUN_NUMBER

If you are still in tmux (with the blueish bar at the bottom), use the tmux command sequence "ctrl+a" then "d". This should detach you from the tmux session.

If the replay looks like it is stuck, you can do a "ctrl-c" and the replay should gracefully exit. When it is finished the tmux pane will close.

Running full replays

Sometimes it crashes or you want to re-do it, then run:

./bin/hc_coin_replay -r RUN_NUMBER -n -1 

./online_bin/auto_replay_stat

Running the Scandalizer

If the CSS alarm handler (modern-ish looking one) is not being populated. The scandalizer has crashed (due to a known bug). You can manually run it by

./online_bin/scandalizer -r $(latest_run -t coin) -n -1 -s $(latest_event_number)

2018-2019 Run Plan

Goal

The goal of the E12-09-002 experiment is to measure the ratio of semi-inclusive pi+ and pi- production from LD2 for the purpose of looking for Charge Symmetry Violation (CSV) in quark distributions.

Experimental setup

• Main trigger is 3/4 in the HMS in coincidence with 3/4 in the 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 50 muA for pi- and 25 muA for pi+. The main goal is to keep the total rate in the pion arm the same at both polarities (500 kHz or less). If the rate exceeds 500 kHz, please adjust the beam current accordingly.
• Trigger:
  • Main trigger is 3/4 (TRIG 4) in HMS in coincidence with 3/4 (TRIG1) in SHMS.
• Prescale: PS6=0 all the time. Adjust PS4 to give at least 100 Hz (and no more than 200 Hz) of HMS singles.

  • https://hallcweb.jlab.org/wiki/index.php/5_pass_Run_Plan#Kinematic_Group_15 Do kinematics 16-11 (pi-) and then 15-11 (pi+). For these last 2 settings, scale the requested charge to account for the time remaining before 8 am. Both polarities are required, so plan to spend about half the remaining time on each.
