• The CEBAF Glassman HVPS has the capability to produce -250 VDC for biasing the gun electrode to generate photocurrent for laser/gun alignment. It is not calibrated yet for QE measurements, but should be sufficient for producing QE maps. This was implemented by J. Hansknecht. The summary of the function with picture may be found in this logbook entry: https://logbooks.jlab.org/entry/4158694
