The JM-400 electrostatic pulse accelerator developed by our factory in July 1981 is a small accelerator that can be used for activation analysis, neutron source research on neutron flight time and irradiation. It can be applied to defense, industry, agriculture, research and education and other fields. The device adopts horizontal structure, its energy adjustable range is wide, can provide direct current and pulsed beam, with compact structure, stable and reliable operation, easy maintenance and so on, reaching the domestic advanced level. Its main technical performance is: 1. DC maximum operating voltage of 400 kV, the maximum operating current of 4 mA, the voltage stability of not less than 4% within 1% of the DC voltage from 200 kV to 401 kV continuous Tune 2. When the operating voltage is 200-300 kV, the hydrogen ion beam current in the DC state (or pulsed state) is not less than 1 milliampere (ie no magnetic analyzer is installed) and the target flow spot diameter is under 10 mm. 3. High-frequency ion source: pulse frequency: a single, 10 to 10,000 times / sec continuously adjustable. Pulse width: 10 ~ 10000 μs continuously adjustable.
