Abstract :
At the 100 MeV proton linac of the KOMAC (Korea Multi-Purpose Accelerator Complex), the low level RF system provides field control for the entire KOMAC proton linac, including an RFQ and a DTL1 at 350 MHz as well as 7 DTL cavities at 700 MHz. In addition to field control, it provides cavity resonance control, and incorporates the personnel and machine protection functions. An accelerator electric field stability of ± 1% in amplitude and ± 1° in phase is required for the RF system. In order to accomplish these requirements, a digital feedback control technique is adopted for flexibility of the feedback and feed forward algorithm implementation. In this paper, the detailed description of the low level RF system is given.
