SL: Min Huang
TO: Toby Badman
3rd: Mohamed Hafez
0:00 Shift starts with production runs at 1.441GeV
1:20 kalyan suggested to ask MCC changing BPMA/B positions to the values
we had during swing shift. Kalyan and Chao were watching bpm positions
and 3rd arm rate.
1:50 Kalyan suggested asking MCC to change IH01.xpos from -3 to -4, then
all the way to 0. 3rd arm rate came back to 1.7k good value.
1:55 Continue production runs at 1.441GeV
4:10 Finish production at 1.441GeV. Changing HRS p0 to 1.3405GeV.
The septum currents were found wrong later.
4:22 Hall C change IHWP to be OUT.
Beam trip. Take a bleed-thru test.
5:40 Turn on slow raster. Cycle LHRS to 2.228 elastic setting and set
septum current to get ready for packing fraction runs. Take on NH3
top&bottom.
6:25 Move LHRS to 1.3405, set septum currents accordingly, turn off slow
raster, retake dilution runs.
7:15 Turn on slow raster, move target to NH3 top, polarized to 28.8%,
start production runs at 1.3405GeV.
8:00 Shift ends with production on-going.
