摘要：
A long-focus electron gun is described, capable of producing beams of intensity up to 230 mu A at accelerating voltages 25 and 50 kv. The minimum beam half-width is approximately 0. 2 mm at a distance approximately 0. 8 m from the directly heated tungsten cathode. The power supply is based on blocks of the EMMA-2 electron microscope.
