A pulsed electron gun consisting of a beam forming electrode at cathod
e potential, a non-intercepting modulating anode to control the emissi
on instead of a fine mesh grid and an accelerating anode is described.
Once a second it delivers a 2.6 mu s pulse of 120 mA at 40 kV. Experi
mental optimization of modulating anode voltage was done and the resul
ts are discussed. The gun is being operated in temperature limited con
ditions. The power supply features are briefly outlined.
