RC Report

  • RC: Wenliang (billlee) Li, billlee@jlab.org


CW could be sent to Hall A. A & C couldn't be brought up simultaneously (there could still be an issue). He3 target was not ready due to a position switch issue. Collected 4 hours of reference Cell data (H2) overnight. Overall, we have production beam onsight, and MCC day shifters are eager to give Hall A high-quality beam. We should be back online soon.
