AIOP - Polarized Photon Source
Agenda:
- Previous Meeting
- Announcements
- Project Progress

- GitHub AIOP Project (AIOP-Photon issues)
- Task assignments (FTE Profiles)
- PIER Activities
- Middle School Data Science Hackathon Workshop
- HUGS mini-Workshop
- AOT
Minutes
- Reviewed previous minutes:
- Contention in nudge counts between patrick and jiawei’s algorithms
- Slides from last time have been uploaded
- Project Progress
- Patrick shared slides
- Jiawei had 1123 nudge events vs 1241 for Patrick (~10% down from much greater)
- Looking over all spring 2020 (double check…may be 2018 fall)
- Some discrepancies solved
- Beam down times with nudge events
- @is_dirc_production and @status_approved tags not used before
- 10 second window since goni changes
- Still 10% difference
- Going to look event by event
- David: Are the remaining events overlapping?
- Patrick: a couple hundred unique to each set. Maybe the timing (tagging) is slightly off
- Thomas: any other variables to tag events
- Patrick: yeah maybe duration, or end times. Etc.
- Slide 2 on Livingston c
- Tried to confirm c=k/gEo(...) using Hovanes script
- The script doesn’t seem to map pitch and yaw to delta c
- Hovanes needs to look at formula to agree. Looking at the formula x axis of slide 3. Patrick will provide this talk and the derivation for confirmation
- 45/125 vs 0/90 may be problematic
- Naomi: pass the numbers from a small subset of events to hovanes?
- Agreed to hand over the numbers
- Some discrepancies solved
- Jiawei showed slides
- Some nudges were alignment change oopse
- Measured drift amounts (from start and from nominal)
- Spring 2020 looks best
- Hovanes notes the number used as “nominal” really used as fit starting point.
- Naomi: wasn’t fall 2018 had a flat top and needed a new spot?
- Hovanes: bottom line: don’t use CBREM:REQ_EDGE
- Naomi: may be able to get the required from Alex wiki
- How is the beam spot determined
- Naomi: look for most uniform thickness place
- Looking at Richards calculator
- There may be a way to change from goni pitch/yaw x y to diamond spot. Hovanes thinks both Richard and hall look at beam spot from the same side. Some radiators are missing from the dropdown
- Hovanes: you need Zygo plot not beamspot
- David: proposal mentions beamspot to do digi twin
- Patrick: No reliable offsets right Hovanes?
- Hovanes: no reliable offset
- Hovanes sent a link: <a href="https://docs.google.com/spreadsheets/d/1v2lTIeHomF46NVSnvGhSi8oYJj6Tkd3zv341_EqYlrs/edit#gid=0">https://docs.google.com/spreadsheets/d/1v2lTIeHomF46NVSnvGhSi8oYJj6Tkd3zv341_EqYlrs/edit#gid=0</a>
- We looked at an example Zygo plot
- Patrick asked Hovanes about the use of the script.
- Hovanes: yes it is used. Buried in scripts and scripts
- What is the process
- Hovanes: shift worker looks and clicks a button and it shifts the goni. The button click runs the script to know how to adjust the goni
- PIER activities
- Meeting with Lisa biweekly
- ~30 kids on chrome books
- Need to reserve F113
- Thomas working on draft agenda
- Patrick shared slides
