Description

A 500 MHz normal-conducting (NC) cavity is being developed for Super Tau-Charm Main Rings which have a current of 2 A and a synchronous radiation energy loss of 410 keV per turn. This NC cavity operates in a higher order mode of TM020. Through optimizations, it results in a high quality factor and a low R/Q. This feature is beneficial to reduce the required detuning frequency so that the coupled bunch instabilities (CBIs) driven by the ac-celerating mode are greatly suppressed. It employs ferrite absorbers inside coaxial slots located at the node of the TM020 mode to heavily damp all of dangerous parasitic modes except from the TM020 mode.
