  Moscow University race-track microtron (RTM) control system is a star-shape network of LSI-11 compatible microcomputers. Each of them is connected with RTM systems via CAMAC; optical fiber coupling is also used. Control system software is designed on Pascal-1, supplemented with real time modules and Macro. A unified real time technique and re-enterable data acquisition drivers allow to simplify development of control drivers and algorithms. Among the latter three main types are used: DDC methods, those, based on optimization technique and algorithms, applying models of microtron’s systems. Man-machine interface is based on concept of the "world of accelerator". It supports means to design, within hardware possibilities, various computer images of the RTM.

  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.
