Abstract:

A 20 KV electron beam multiplier EBM tube has been made to deliver a 10 ampere positive pulse of one microsecond or more in duration at 100 to 1,000 pps. The diode voltage was 125 volts saturation point. Another tube delivered an 8 ampere pulse at 70 volts. The current gain has been consistently in the order of 5,000. A modified standard TV electron gun gave -40 volts grid cut-off at a beam current of 4 millamperes and 20 KV anode potential. Slightly different modifications gave -13 volts cut-off at 1.0 ma beam current. There is every indication that a further modification could give -20 volts or less cut-off at a beam current of 3 to 4 milliamperes based on the most recent experimental guns. Deterioration problems are encountered in the diode. These are analyzed in a consideration of EBM diode design. Author
