<b> PROD66</b> and the trigger <b>rgm_6GeV_inb_v1_0.trg</b>, 100 M events (max 4 hours) per run.
 
  
* Continue to take Empty target run at 250 nA until 9 AM (November 23)
+
* Installation of 40Ca target until 3:00 - 4:00 PM
* 9am: Take beam away and call Eugene on beamline expert phone to ramp down magnets
+
* Ramp up magnets, pump down beamline
* ~10:30-11:00am: When magnets are down, take zero field runs. Start with <b>4nA</b> and just increase up to 6-7nA if rates allow it. Use trigger <b>rgm_zero_field.trg</b> and update GUI according to Valery's introduction (https://logbooks.jlab.org/entry/3948092)
+
* ~4:00 PM when beam is handed back start beam checkout procedure going to tagger then to Faraday cup.
* 11:00-16:30: Zero field runs
+
* Perform a target scan of the 40Ca target following the procedure listed under "Physics-Quality Beam"
* 16:30: Ask for beam away and survey of the hall to drop to restricted access. Target work to switch to Ca-40 will start
+
* Record new beam positions after full beam checkout procedure is done
