Description

Accelerator kickers, which commonly use ferrite and other insulating materials, can encounter High Voltage (HV) performance limitations due to interactions with the particle beam. These interactions, driven by electron cloud buildup and charging phenomena on exposed surfaces, can negatively impact kicker performance, particularly at high beam intensities. To mitigate these effects, surface treatment techniques are investigated to improve the HV kicker performance under such conditions.
A dedicated setup has been developed to perform HV testing of treated surfaces in both ambient and in vacuum conditions, closely simulating operational environment. This paper presents insights into the effects of these surface treatments on material properties, supporting strategies to enhance HV kicker reliability at higher beam intensities.
