AIOP - Polarized Photon Source

Agenda:

Previous Meeting
Announcements
Project Progress
- Data mining/preparation
- GitHub AIOP Project (AIOP-Photon issues)
- Task assignments (FTE Profiles)
PIER Activities
- Middle School Data Science Hackathon Workshop
- HUGS mini-Workshop
AOT

Minutes

Attendees: Thomas B., Torri J., Patrick M., Jiawei G., Cristiano F., Malachi S., Armen K.

Malachi introduced Armen Kasparian from the Data Science Dept. who will be working with us on this project

Torri, Patrick, and Jiawei met/communicated to coordinate the data preprocessing efforts.

Data Preprocessing (Patrick)
- Patrick showed some slides.
- Looking at GlueX Phase II (Spring 2023) and CPP (Summer 2022) data
- Both periods used the same 50um diamond
- Extracted data from EPICS archive in 1sec steps
  - Dropped steps with missing info
  - First attempt to identify some nudge events within data set
  - Applied energy map to TAGM and TAGH scalers
    - Some question as to what the "amorphous scalers" represented
  - Applied standard fit to scaler spectra to identify coherent edge and extract polarization
  - David asked if data points were interpolations or actual measurements. Patrick will look into it.

Data Preprocessing (Jiawei)
- Jiawei showed some slides.
- Looking at Spring 2018, Fall 2018, and Spring 2020 data.
- Able to identify nudge events from pitch/yaw settings in EPICS archive
- Extracted from archive and converted to CSV format
  - Included integrated beam current
- Some discussion on how to get beam position on diamond using beam position monitors and goniometer positon
  - Ask Hovanes or possibly Richard how to obtain this

Action Items

Determine if mySampler returns interpolations between data measurements, or the measurements themselves (Patrick)
Give some visuals indicating 30 seconds is a good amount of time to wait for the beam to ramp up and the coherent edge to stabilize (Patrick)
Get some information about nudge events: how many, when they happen, etc (Jiawei, Patrick)
Diagram of tagger microscope and hodoscope (?)
Send link to amorphous subtraction code for online monitoring (David)
Find how to get beam position on diamond (Jiawei)
Place data in central location and document (/group/halld/AIOP/data - Torri, Patrick, Jiawei)
