Emittance Measurements, September 3, 2015
- We measured (normalized) emittance and Twiss parameters for the horizontal and vertical planes as a function of momentum (6.7, 7.7 and 8.3 MeV/c).
- The results from a previous measurements is summarized in JLAB-TN-14-004 (February 2014): Transverse Beam Characterization in the CEBAF 5 MeV Region

Bubble Chamber Digital Camera with beam in Injector
- On Tuesday August 11, around 9:30 - 10:05 pm, we tested the bubble chamber sensitivity to gammas with beam to Faraday Cup 2 and 5D line. We did not see any thing on camera, none of the pixels showed any activity, nothing.
These were the beam conditions:
- 30 uA CW (6.3 MeV) at Faraday Cup 2
- 10 uA CW at 5D Line radiator/dump
- 10 uA CW at 5D Line Faraday Cup
