Abstract : Electron beam multiplier (EBM) tubes were further developed to give a 10 ampere positive pulse at 300 volts for a bare junction silicon diode with heat sink. The beam current was in the order of 2 ma. at 20 KV. The current gain was thus 5,000. This was confirmed also by D. C. measurements at low current. The grid pulse was 1 microscecond in duration at 100 pps. These improvements were achieved mainly by modifications in processing to greatly reduce contamination of the diode. Electron gun development has given a 4.0 ma beam current at zero bias and a cut-off of -40 volts. Modifications of electron gun design are in progress to reduce the grid cut-off voltage by a factor of two. The heat sink for the diode was improved with a ceramic lead-in insulator to eliminate gas leakage trouble. (Author)
