Status of the ETA-II linear accelerator: High brightness results

Conference ·
A two-aperture collimator has been used to measure brightness of the electron beam produced by the injector and the first 20 acceleration cells of the ETA-II linear induction accelerator. Osmium alloy dispenser cathodes produce the electron beam. For accelerated currents up to 1.5 kA with 2.0 to 2.7 MeV beam energies the measured brightness is 4 /times/ 10/sup 9/ A/(rad-m)/sup 2/, exceeding our design goal by a factor of 2. At the highest current, 2.0 kA, a beam brightness of 2.6 /times/ 10/sup 9/ A/(rad-m)/sup 2/ has been measured. 6 refs., 5 figs.
