Brightness Measurements on the Livermore High Brightness Test Stand

摘要

Several techniques using small radius collimating pipes with and without axial magnetic fields to measure the brightness of an extracted 1 - 2 kA, 1 - 1.5 MeV electron beam will be described. The output beam of the High Brightness Test Stand as measured by one of these techniques is in excess of 2 x 10 exp 5 amp/cm exp 2 /steradian. 5 refs., 4 figs. (ERA citation 10:052180)
