  The project of a10MeV PET cyclotron accelerator for medical diagnosis and
treatment was started at Amirkabir University of Technology in 2012. The
low-level RF system of cyclotron accelerator is designed to stabilize
acceleration voltage and control the resonance frequency of the cavity. In this
work Intelligent Low Level Radio Frequency Circuit or ILLRF suitable for Most
of the AVF cyclotron accelerators was designed by the beam monitoring device
and narrow band tunable band-pass filter. In this design, for the RF phase
detection does not need to signal processing by microcontroller
