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

Slug 17

  • 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

Slug 18

  • IHWP: IN
  • Wien: Right
  • Current: 70 uA
  • Total Good Runs: 8
  • Total Good Charge: 1.27C
  • HRSs: Both arms
    • PREX 1 thick Quartz (RHRS) and 5mm Quartz (LHRS)
  • For some of the runs LQ1 tripped, applied bad_evt_cut

Slug 19

  • IHWP: OUT
  • Wien: Right
  • Current: 70 uA
  • Total Good Runs: 6
  • Total Good Charge: 0.87C
  • HRSs: Both arms
    • PREX 1 thick Quartz (RHRS) and 5mm Quartz (LHRS)
  • For some of the runs LQ1 tripped, applied bad_evt_cut

  • Current: 70 uA
  • Total Good Runs: 5
  • Total Good Charge: 0.88C
  • HRSs: Right arm only
    • PREX 1 thick Quartz (RHRS) and 5mm Quartz (LHRS)
  • Note: During slug19 LQ1 completely failed to work starting run3718 and we decided to upgrade all the runs from 3718 to 3732 to slug20 even if the IHWP status didn't change

Slug 21

  • New PREX II Quartz in Right Arm also now

Slug 22

Slug 23
