Electron guns for spacecraft

Studies of three versions of electron guns (0.3 kV, 0.14 A; 20 kV, 0.1 A; 40 kV, 0.05 A) intended to operate aboard spacecraft during various space experiments are presented. The computer simulation results of electron-optical systems are given, the optimization of cathode-heating units and heat rem...

Beschreibung
Zusammenfassung:	Studies of three versions of electron guns (0.3 kV, 0.14 A; 20 kV, 0.1 A; 40 kV, 0.05 A) intended to operate aboard spacecraft during various space experiments are presented. The computer simulation results of electron-optical systems are given, the optimization of cathode-heating units and heat removal system are performed, circuit design of the gun power supplies for both the stationary mode and using a special modulator are discussed.
