−
* 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 [https://docs.google.com/presentation/d/1zdBw3Ed3sP9p1tl8uPvpETMc-WnDyKF62fOaS487qCM/edit?usp=sharing 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.
