Tests of the field emission cathodes have shown that by using velvet cathodes, the authors have improved the brightness of the ATA injector by a factor of ten as compared to the plasma board cathodes. They have also improved the uniformity of the beam both spatially and temporarily and have found the cathodes to be very repeatable on a shot-to-shot basis. Since their tests in the fall of 1984, the authors have run field emission cathodes exclusively on the ATA injector.
