Thermostabilization system of VEPP-5 preinjector

Technically the system of thermostabilization supposed to be performed by two-contour water scheme. All elements to be stabilized are connected in parallel to the inner closed water contour. Stabilization of temperature is realized as a controlled heating of input water by the heating unit, individual for each element. Dumping of heat surplus is produced by the heat exchanger. This construction allows to stabilize the cooling water flow through the elements, to decrease the power consumption, to change the individual heating conditions for each element of accelerator to compensate the tolerance in RF parameters during the adjusting process. Main characteristics of the system are shown. At the present time the assembly of water contours is in progress. The heating unit that consists of heater, controlled power supply, flow meter, thermistors and control device, has been completely designed, tested on preinjector prototype and now is in serial production
