Target lab:

• Jing and Ameya:

     - Plugged back everything.
     - Did coil calibrations.
     - RF coil calibration: don't get enough power --> need to change the amplifier and check capacitor box.

W&M:

• Todd:

     - Seonho and Wolfgang compared their Blumlein-Bottcher calculations: the errors look similar.
     - Got potassium and will try to make an hybrid cell.
     - working on NMR using frequency sweep.

Small angle GDH:

• Jaideep:

     - Created a code to extract halog variable values.
     - Writing several technical notes.


• Vince:

     - Optimization: looking into x_tg calculation in ESPACE -- > calculation error might probably be causing optimization problems.
     - Began working on DNP presentation.
     - Working with Jing and Ameya on the field calibrations and with Richard on wall thickness.
     - Coherent #1 was shipped.


• Tim:

     - Bleedthrough study.
     - Attenuator had no effect..

Spin duality analysis:

• Patricia:

     - BPM/ raster correction done: about (50 * 2) runs needed to be corrected for beam drifts.
     - Regenerated all Ntuples and now creating all histos.
     - Looking at VDC's Ntrack=0 problem --> at the first look, the problem doesn't exist anymore in these Ntuples.
     - Comparing Ring Buffer and scalers
     - working on pion rejector re-calibration.

     Plan
         - Be done with all above before leaving to France.
         - Then will start elastic analysis.

Small angle GDH:

• Vince:

     - finishing the minutes of the last collaboration meeting.
     - Optimized y_tg at 6deg; After adding BPM info, y_tg went a little bit off.
     - from y_sieve vs x_sieve plot, strange behavior on the edge can be seen.


• Tim:

     - Looking at data when slit was wide open.
     - comparing data with open slit at different energies.


• Jing:

     - working on PID detectors calibration.
     - working on setting back the target lab.

Spin duality analysis:

• Patricia:

     - Elastic and delta asymmetries at E=1GeV.
     - Looking into pion rejector calibration.
     - regenerate ntuples without using filter.f
     - a lot of elastic runs failed at the replay.

     Plan
         - BPM/raster calibration by correcting for beam position drifts.
         - comparison between Ring buffer and Scalers data.
