Rated values of linac beam power depend basically on a microwave power input and stability of the phase. The latter is sustained by means of thermostatic control for the sections subject to the powerful microwave warming-up. Demanded both high accuracy of stabilization and low settling time of temperature for linac modes define development of the control system.
