    • Likely a leak in the Helium-3 cell which was fixed by Dave
    • Warm up and recover Helium-3.
    • Fill Helium-3 cell with Helium-4 and check for leaking over the next several days.
    • If it appears stable, return the Helium-3
  • Target boiling study: SHMS at 20.0 degrees (-4.4 GeV) and HMS at 20 degrees (-4.4 GeV)
    • Finished He-3, He-4, Dummy, and limited carbon before beam stopped at 8 am.

Run Plan
