* Turn ON calorimeter and the hodoscope, run DAQ (even if no SVT, only ECal and hodoscope) with 8 um W target and 100 nA. Record trigger rates (dump the trigger GUI into the logbook). With any problems with DAQ call the expert cell phone

* SVT commissioning (Cameron)
+
* Continue with SVT commissioning (Cameron)
** Run baseline measurements to set the threshold
+
** Setup nominal trigger and take data with 8 um W target at 70 nA, check occupancies in SVT using DQM, move SVT to 1.5 mm and take more data  
** Time-in SVT, requires moving to 3 mm from beam position
+
** If conditions are right, occupancies are low move to 1 mm
* Setup nominal trigger and take data with 8 um W target at 70 nA, check occupancies in SVT using DQM, move SVT to 1.5 mm and take more data  
 
 
* If SVT is not ready, take FEE runs with ECal, 8 um target 150 nA. Each run 4 hours long, PROD77-NOSVT  
 
* If SVT is not ready, take FEE runs with ECal, 8 um target 150 nA. Each run 4 hours long, PROD77-NOSVT  
 +
* When MCC is ready, perform beam tune to get read of beam tails, call Stepan on RC phone

==Hall Access:==
 +
* Investigate noise in ECal top - Nathan/Ben (4 hours)
 +
* Replace/relocate the camera on the SVT chiller - Nathan (30 min)
 +
* Investigate halo counter readout for HPS_R (pie tower) and HPS_SC (space frame) - Stepan (1 hour)
 +
* Add one more channel of halo counters to beam modulation scheme - Stepan/Nathan (1 hour)
