Low Level RF Control of Cyclotron for Neutron Capture Therapy System

A versatile digital Low-Level Radio Frequency (LLRF) system has been designed for the various energy cyclotrons being developed by Korea Institute of Radiological and Medical Sciences (KIRAMS). In this study, the contents of LLRF of $\pmb{8\mathrm{MeV}\sim 30\mathrm{MeV}}$ cyclotron, which is a typical circular accelerator for neutron capture therapy, are discussed. Here we present blue print to construct an effective LLRF control system of the cyclotron.
