• Status
  • Data taken so far [1]
  • Beam quality [2]
    • Beam issues, no data until 21:40pm
    • Lost ~90minutes due to beam dump water flow alert (see below).

• Requiring attention
  • Around midnight beam dump water flow alert (flow too high) [3]
    • Ultimately resolved by masking [4]
    • BUT... around 10:30 downtime created for the same alert [5]
    • Again resolved by masking ...after 49 minutes
    • Need to make sure this gets communicated to the next crew if needed
  • RadCon wants to put a small detector in the SHMS hut during the next opportunity
    • Needs few hours, communicate with Brad when next opportunity arrises

• Plans - Physics
  • Take data at Q2=3. W=3.14 x=0.25 theta_Shms=9.42 to reach 66% of desired stat. goal., then take Al.
    • Projected to take until tomorrow 4pm
  • Change SHMS angle to 6.48 deg, take Al and LH2 data
    • Coordinate with Holly in case we trigger rotation alarm.
    • Coordinate with Jay to see if we still need new limits for the ion chamber diffusors at this angle [6]
    • Projected to put us sometime in the weekend
  • Start preparation for 2-shift luminosity scan
    • Will need stable beam for this, and experienced shift
    • Communicate with Jay Benesch to find best time, might have to be opportunistic
