* Continue data taking for trigger studies at 100% torus field (negatives inbending) and solenoid to 100% field. DAQ configuration PROD (selected by clicking on Configure before the Download), trigger file will change depending on the specific test (selected at the Download), beam position as indicated above. Select the beam current to have a trigger rate <12-13 KHz up to a maximum of 30 nA. For each selected current, make sure FSD thresholds are set correctly (refer to the "Establish-physics quality beam" procedure at [https://wiki.jlab.org/clas12-run/images/e/e3/Estab_beam.pdf]), integration time is set to 5 ms, and that the orbit locks are on.

* Continue data taking at 100% torus field (negatives inbending) and solenoid to 100% field. DAQ configuration PROD (selected by clicking on Configure before the Download), trigger file elec_htcc_1phe_pcal_300.trg (selected at the Download), beam position as indicated above.

** <s>Trigger study #1: trigger file tr_electron.trg, 1 h run.
+
** 75 nA: 2 h run
** Trigger study #2: trigger file elec_pcal_xxx.trg with xxx = 200, 300, 400, 20 min. or 10M event runs.
+
* At 7 pm, the FT expert will take half an hour to test different HV settings on the FTHodo;
** Trigger study #3: trigger file tr_pcal_100.trg, 1 h run or 20M events.
+
* At 7:30 pm, the DAQ expert will test new threshold settings on DC R2 to suppress the electronic noise;
** Trigger study #4: trigger file htcc_7phe.trg, 1 h run or 20M events.
+
* Once these tests are complete, continue data taking with elec_htcc_1phe_pcal_300.trg:
** Trigger study #5: trigger file elec_htcc_xphe_pcal_300.trg with x=1,3,5, 20 min. or 10M events runs.</s>
+
** 50 nA: 3 h run until 12 am
** Trigger study #6: trigger file random_tr.trg, take data for 5 hours.
+
** 25 nA: until 8 am
* Once the special trigger runs are completed, start luminosity studies with elec_pcal_300.trg trigger:
+
** From 8 pm to 12 pm: the RICH expert will take special runs at fixed current (50 nA) and with the same trigger as before but changing RICH operating parameters
* 25 nA: 50 M events
 
* 50 nA: 50 M events
 
* 75 nA: 50 M events
