Bubble Chamber Beam Test August 2015

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-14-004T: Transverse Beam Characterization in the CEBAF 5 MeV Region media:TN-14-004.pdf media:TN-14-004.docx

Beam Charge

This is a test of 5D line, the chamber is off.

1. Beam Optics to 5D
2. Measure beam charge
3. Maximum 1/4 Cryo-unit gradients
4. Measure beam energy
