Minutes
Attendees: David L., Thomas B., Torri J., Patrick M., Jiawei G., Cristiano F., Malachi S., Armen K.
- Some of our data needed to be moved out of /group/halld by request from Alex A. The disk was getting full.
- Some of the files were old Hydra models
- Wiki needs to be updated with new location of AIOP-relevant files
- Jiawei showed some slides
- Statistics for identified nudge events for 3 run periods were shown
- Criteria for identifying nudge events reviewed
- Primary mechanism is to look for changes in the setpoint values
- Most nudge events happened within 5 minutes just before starting a run
- Some run periods had 30-40 nudge events identified during a run
- Hovanes noted:
- The pitch and yaw values will not change when switching between amorphous and diamond (only roll, x, y)
- Radiator ID should be used to identify whether we switched to another diamond
- There are "fast" and "slow" nudging buttons which correspond to step sizes that differ by about a factor of 10. The "fast" represents the larger step and will take a correspondingly longer time to complete.
- It may take around 6 weeks to 2 months to damage a spot on a diamond enough to move to a different location
- This is decided by the Run Coordinator and typically is based on the sharpness of the coherent edge and the availability of fresh areas on the diamond.
- Patrick showed some slides
- Focused on Spring 2023 data
- Extensive discussion on what mySampler is doing, nudge criteria, etc.
- The statistics for identified nudge events differed from what Jiawei was seeing for other data sets.
- Patrick suggested running his algorithm on the Spring 2020 data set in order to compare with results from Jiawei's identifier on the same data set.
Action Items
- Update wiki with new file locations after having to move them from /group/halld (Torri)
- Send link to mySampler manual (Hovanes)
- Compare nudge event identifiers for Spring 2020 data (Patrick, Jiawei)
