- Status
- Requiring attention
- Around midnight beam dump water flow alert (flow too high) [3]
- 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
- 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.
