Description

The diode type electron source is designed on the basis of lanthanum hexaboride emitter with a contact pyrolytic graphite anisotropic heater. The first electrode of an accelerating tube serves as the anode of the electron source when using in a high-voltage accelerator. The electron source is designed for the electron beam current under the constant mode up to 100 mA. And emission current density is 0.4-0.6 A/cm2. Intense heat power does not exceed 50 W at intense filament current of 10-15 A. To determine source reliability, statistics on failures for 20 cathodes operating at high-voltage accelerators. Time to failure for a separate cathode is 250 hrs - 15.500 hrs. The total time to failure for 20 cathodes is 88389 hrs, and a number of failures is 7
