| Abstract |
In order to obtain an electron beam with an excellent energy resolution and stable characteristics, a tight control of the amplitude and phase of the field in all rf accelerating sections is required. The high rf power level, dissipated in the accelerating section (AS), together with temperature dependence of the AS resonance frequency caused the creation of the original control system of resonance frequency. Amplitude, phase and resonance frequency local feedback control system have been designed. All systems are computer controlled analogue single loops. The control loops guarantee stable, repeatable amplitudes (10⁻¹ relative error), phases (± 0.5°) of the rf fields in AS, resonance frequency of AS (± 2 kHz) and have optimal bandwidth. A model of feedback loops has been developed that agrees well with measurements.
