Current Status

• Coffee maker working!!! (thanks Paul)! https://logbooks.jlab.org/entry/4052331

Current Run Plan

• Complete SHMS paddle study
• Proceed to 26 degree settings for SHMS/HMS -> start with lowest momentum setting
• Call RC and Casey to check PID trigger levels at this setting
• Proceed to highest momenta at 26 degrees

Notices in Effect for Shift Crew

• Pay attention to DAQ prescale settings
• Update EDTM setting to give ~15 Hz AFTER prescale (see table near DAQ computers)
• Use good electron fraction from 50k replay to estimate how many events will be needed to get required statistics

Current Issues

• SHMS NGC PMT1 HV set back to 1700 (https://logbooks.jlab.org/entry/4052210) we'll need more elastic data to get efficiency
• Need to analyze SHMS paddle study ASAP to determine how we'll run 8 degree data
• cermode10 in the SHMS causes significant dead time (https://logbooks.jlab.org/entry/4052716) - should we turn it off?
