Overview 
- The Hall is in Restricted Access
- Tonight the GEMs will be conducting tests under HV. SBS magnet powering tests are ongoing. 
- We have liquid Deuterium and Hydrogen, so we have a TO on shift.  Shift Leader shifts remain **on call**.  

Path to Beam in the Hall
- Jack and his team are working on powering and ramping the SBS magnet to its 2100 A max current, and wrapping up work on providing signals to accelerator for the FSD system; accelerator is working on software related to this as well.  This work will continue Friday and through the weekend with the goal of bringing beam into the Hall starting first thing Monday Day shift.

RC update from the 3:15 pm meeting is here: https://sbs.jlab.org/cgi-bin/DocDB/public/ShowDocument?docid=123

Further updates from other systems are below. 

Analyzer/Software
- Debugging official global replay script 
- Preparing code for zero-field and optics analysis
- Minimum bias simulations for zero field, sieve IN. Preliminary optics/alignment
- Panguin configuration: Most config files ready. 

DAQ
- Combined configuration running and testing continues yesterday.  

GEMs
- Taking data tonight, resuming test on gas check.
- Difference between GEM DAQ (standalone) and Combined DAQ.
  - Trigger on standalone: BB Shower. Latency shouldn't be different

HCAL
- Coincidence trigger checks (Arun, Mark, Scott)
  - Need combined run to see the pulser
  - Nearly done in the hall.  LED work needs access -- aim to be finished today
- PMTs swapped back (bad modules) -- those will have worse energy resolution
- Sebastian working on energy calibration code (thanks for help from Eric)
- Cleaned up and ready for beam
