Minutes

Attendees: James M., Naomi J., Malachi S., Torri J., Thomas B., Jiawei G.

Naomi gave brief update on the 5-min lightning talk she gave at the recent Hall-D Polarized Target workshop
- She noted Ken Livingston showed interest in the project. We should send him a link to the proposal.

Still some access issues with Github Project. Patrick and Jaiwei need to be added to JeffersonLab organization. (David can do that)

Torri showed some slides on preliminary data logging along with a few plots
James already had some extensive information in a number of files in JSON format
We discussed the nature of the NMR data that was collected.
- It involves sweeping through a range of frequencies over a ~3min time period
- Multiple passes are made and the average of the values at each frequency recorded to give an waveform
James explained some issues with RG-C data from CLAS12 due to coils being outside of the target instead of inside where they would normally put them.
- The external coils make the NMR more sensitive to beam position. The beam itself was rastered so illuminated an area of the cup.
- RG-C analysis of elastic events to measure the polarization is ongoing, but currently not in agreement with the NMR measurement
- The elastic event method requires a lot of statistics and the final analysis just uses an average polarization for the entire run.
- Silvia N. is a contact person for RG-C. Torri will contact her to ask about the status and open a dialog.

We discussed extracting the NMR signal from the background. This will involve modeling the background as a function of time.
- James has some files taken as pure background that can help with this purpose.

Action Items

Send link to proposal to Ken L. (David)
Contact Silvia/RG-C (Torri)
