Abstract :
A two-aperture collimator has been used to measure the brightness of the electron beam produced by the injector and the first 20 acceleration cells of the ETA-II (Experimental Test Accelerator II) linear induction accelerator. Osmium alloy dispenser cathodes produce the electron beam. For accelerated currents up to 1.5 kA with 2.0- and 2.7-MeV beam energies, the measured brightness is 4×109 A/(rad-m)2, exceeding the design goal by a factor of 2. At the highest current, 2.0 kA, a beam brightness of 2.6×109 A/(rad-m)2 has been measured
