Electron beam oscillations in ELV-type accelerators, their diagnostics and suppression method

In the article a method for diagnosing electron beam oscillations in ELV-type accelerators associated with the penetration of a transverse magnetic field from the primary and secondary windings into the accelerating tube was described. A method for suppressing these oscillations was developed and tested using the ELV-8 accel- erator with an extraction device capable of extract a focused electron beam into the atmosphere. After sup- pressing the oscillations, it was possible to extract a focused electron beam with a power of 100 kW into the atmosphere and increase the service life of the diaphragms.
