Finer Utility of the Electron Gun for You

The method of using a high-voltage glow discharge to create electronic guns with a cold cathode has been known for more than three decades. Today, the Institutes, being pioneers in the field of the creation of high-voltage glow discharge electron guns (BTP), is the only enterprise in the world, serially their issuing.

Possessing serious advantages – simplicity of manufacture, reliability and a big operational resource (especially in heavy vacuum conditions), VTR guns allow, on the one hand, to implement technologies that are inaccessible to traditional electronic guns and vacuum arcs, on the other – to drastically reduce the costs of creation and operation any electron-beam devices.

The device of the electron gun

Electronic gun VTR 200-300 / 25 is designed for heating, melting, evaporation and modification of materials in process plants of both high and low vacuum. The gun works from any voltage source. No source of heat is required. Power regulation is provided in the range from 0 to 300 kW by changing the supply of working gas – technical hydrogen or changing the value of the supply voltage.

It is also possible to use other gases: air, nitrogen, oxygen, inert gases. But the maximum power can decrease by more than 2 times.

The gun ensures stable operation of any installation with a vacuum in the process chamber no worse than 0.02 mm. gt; Art.

Possible applications: replacement of thermionic guns with existing and newly created technological electron-beam devices for heating, melting, evaporation and modification of materials, especially in heavy vacuum conditions and corrosive environments.

The structure of the electron gun device includes an anode unit, a cathode unit, a high voltage and cooling cathode injection unit, an ionization gauge and a plug connector of an electronic beam control system.

The anode assembly includes a water cooled anodic housing on which a deflection system, a magnetic lens, an ionization gauge measuring the pressure in the gun, and a plug connector for connecting the cable from the electron beam control unit to the gun are mounted. The magnetic lens and the deflecting system are closed with a protective cover.

The high-voltage input section contains a cable high-voltage connector and a “water rheostat” for the safe cooling of the cathode, which is under high potential.
