Agenda:

1. Roger, Kent and Mark: Hall A Beamline Modifications

---

Notes from this meeting:

• Need to quantify the effects of synchrotron radiation on beam properties. Is there any helicity correlated degradation?

• For PREx-II:

1. Need to test Hall A BCMs.
2. Beam modulation coils were removed:
   1. Re-install. Yves will help identify location of the air core magnets on beamline
   2. Beam modulation and accelerator Fast Feedback: is there a need to turn off FFB when modulation is ON? does FFB implement a digital notch filter to attenuate the modulation frequency while passing all other frequencies?
3. Install QQQ cavity triplet in Hall A beamline.
4. Install QWeak Halo Monitors in Hall A beamline (will need new halo target).
