Slug Summary Notes

Slug 0

Slug 1

Slug 2

Slug 3

IHWP: Out
Wien: Right
Current: 50 uA
- BCM noise in BCM an us begins to be a problem
HRSs: Both
- PREX 1 thick Quartz
BCM: an_ds
- Analysis in adaqfs disks is still an_ds3 normalized at this time

Slug 4

IHWP: Out
Wien: Right
Current: 50 uA
HRSs: Both
- PREX 1 thick Quartz
BCM: an_ds
- Analysis in adaqfs disks is an_ds3 normalized at this time

Slug 5

IHWP: Out
Wien: Right
Current: 70 uA
HRSs: Both
- PREX 1 thick Quartz
BCM: an_ds
- Analysis in adaqfs disks is an_ds3 normalized at this time

Slug 6

IHWP: Out
Wien: Right
Current: 50 uA
HRSs: Both
- PREX 1 thick Quartz
BCM: an_ds
- Analysis in adaqfs disks is an_ds3 normalized at this time

Slug 7

IHWP: Out
Wien: Right
Current: 50 uA
HRSs: Both
- PREX 1 thick Quartz
BCM: an_ds
- Analysis in adaqfs disks is an_ds3 normalized at this time

Slug 8

IHWP: In
Wien: Right
Current: 50 uA
- PQB commences
HRSs: Left arm only
- PREX 1 thick Quartz
BCM: an_ds
- This is when we switched to an_ds from an_ds3 (in the maps being used by adaqfs at this time)

Slug 9

IHWP: Out
Wien: Right
Current: 50 uA
HRSs: Left arm only
- PREX 1 thick Quartz
BCM: an_ds

Slug 10

IHWP: In
Wien: Right
Current: 50 uA
HRSs: Left arm only
- PREX 1 thick Quartz
BCM: an_ds
This was a particularly noisy beam motion slug. FFB was off most of the time

Slug 11

IHWP: Out
Wien: Right
Current: 50 uA
HRSs: Left arm only
- PREX 1 thick Quartz
BCM: an_ds
FFB has now been turned on perpetually, and beam motion is stable, but the BPMs are noisier

Slug 12

IHWP: IN
Wien: Right
Current: 70 uA
Total Good Runs: 9
Total Good Charge: 1.40C
HRSs: Both Arms
- PREX 1 thick Quartz in RHRS
RHRS Returns to usability
New PREX II Quartz in Left Arm Only at this time
analog BCMs started being noisy
Tried bpm4ec and returned back to bpm4e for regression
use bpm11X instead of bpm12X

Slug 13

IHWP: Out
Wien: Right
Current: 70uA-50uA
Total Good Runs: 15
Total Good Charge: 2.04C
- Started from 70uA and went down to 50uA because the collimator temperature started increasing
- Many of the runs were under suspicious category because we were not sure about the target performance during those runs
- Now we decided the runs in suspicious category were not hitting copper frame so turned into good runs
HRSs: Both Arms
- PREX 1 thick Quartz (RHRS) and 5mm thin quartz (LHRS)
Burp Cut has been started from this slug

Slug 14

IHWP: IN
Wien: Right
Current: 70 uA
Total Good Runs: 13
Total Good Charge: 2.42C
HRSs: Both arms
- PREX 1 thick Quartz (RHRS) and 5mm Quartz (LHRS)
For some of the runs LQ1 tripped, applied bad_evt_cut

Slug 15

IHWP: OUT
Wien: Right
Current: 70 uA
Total Good Runs: 7
Total Good Charge: 1.37C
HRSs: Both arms
- PREX 1 thick Quartz (RHRS) and 5mm Quartz (LHRS)
For some of the runs LQ1 tripped, applied bad_evt_cut
LQ1 tripped during some of the runs. Needed to apply bad_evt_cut

Slug 16

IHWP: IN
Wien: Right
Current: 70 uA
Total Good Runs: 8
Total Good Charge: 1.44C
HRSs: Both arms
- PREX 1 thick Quartz (RHRS) and 5mm Quartz (LHRS)
For some of the runs LQ1 tripped, applied bad_evt_cut

IHWP: OUT
Wien: Right
Current: 70 uA
Total Good Runs: 6
Total Good Charge: 1.16C
HRSs: Both arms
- PREX 1 thick Quartz (RHRS) and 5mm Quartz (LHRS)
For some of the runs LQ1 tripped, applied bad_evt_cut

Total Good Runs: 6
Total Good Charge: 0.87C
HRSs: Both arms
- PREX 1 thick Quartz (RHRS) and 5mm Quartz (LHRS)
