Plan for this shift (After 10 AM):
#Continue optics data taking without sieve until about 10:45 AM.
#Ask for escorted access to put siev in in both HRSs
#Continue taking optics data for about 1 hr
#At noon, ask for pass change to 2 pass. In parallel to pass change
do the following work:
1. Remove sieve from both HRSs
2. Remove the small added magnet upstream of the target (Bogdan)
3. Change polarity of the both HRSs to +ve (Tech)
4. Change polarity of right septum to +ve (Tech)
After the pass change, take production data.
10:00 Optics data taking undergoing without Sieve in both HRSs.
10:10 Right Q1 tripped.
10:25 Asked for escorted controlled access to put sieve in.
10:45 Access done
10:52 Beam permit, asked for 1 uA beam on optics target with raster off.
11:01 Now the tripped right Q1 is back.
11:28 Target changed from optics to Tantalum.
11:29 Asked for 2 uA beam on Tantalum
11:50 Stopped optics data taking and asked for pass change to 2 pass.
13:30 Sieves are out.
14:30 Controlled access work finished, asked for beam permit. Accelerator has some issues with RF seperators.
15:00 While turninSeptum magnet would not take any current. Asked for short controlled access so as to reset Septum magnet.
16:00 Waiting for beam at end of shift
