چکیده

New storage ring cavity temperature system was successfully operated for the Pohang Light Source (PLS) and increased the stable maximum beam current up to 200 mA. The storage ring cavity for PLS has the plunger-type tuner which is controlled by the phase feedback loop to always tune the resonant frequency. Optimum temperature windows for the PLS cavities were obtained by intensive but tiresome measurements. The measured results is compared to the calculation based on the relations expressed as a function of the tuner position.

SIMULATIONS AND RF MEASUREMENTS OF THE FUNDAMENTAL AND HIGHER ORDER MODES OF THE THOMX 500 MHz CAVITY*

The RF system of the ThomX storage ring consists in a 500 MHz single cell copper cavity of the ELETTRA type, powered with a 50 kW CW solid state amplifier, and the associated Low Level RF feedback and control loops. The low operating energy of 50–70 MeV makes the impedances of the cavity higher order modes (HOMs) particularly critical for the beam stability. Their parasitic effects on the beam ...

Rhic 28 Mhz Accelerating Cavity System*

The 28 MHz accelerating system consists of a quarter wave cavity driven by an inductively coupled 100kW tetrode amplifer and 1kW solid state driver amplifer. 40dB of rf feedback closed around the cavity and amplifers reduces small perturbations within the loop by a factor of 100, and reduces the time required to shift the phase at transition by a factor of 10, limited by the saturation of the d...

A new tuner control system of spoke superconducting radio frequency (SRF) cavity has been developed and applied to cryomodule I (CM1) of C-ADS injector I at IHEP. We have successfully implemented the tuner controller and achieved a cavity tuning phase error of ±0.7° (peak to peak) in the presence of electromechanical coupled resonance. This paper will present the preliminary experimental result...
