Work on modernisation of the systems of cooling was conducted the cyclotron of У- 120 on three directions: visualization after the presence of channel of water is in knots and systems of accelerating modernisation of the system of cooling of 1th contour termostabilizatijn of 2th contour of cooling. Cooling of knots and systems of cyclotron shows by itself the double- contour system. The distilled water flows in the first contour. He consists of two tanks by a capacity 6 м3, each, water pump and pipes and hoses.. Necessary temperature condition of water 1th to the contour 23 ° - 29 ° С. Distilled water turns out in distillers that are in building.Heated water of 1th to the contour on an exit cools down in a heat-exchanger water of the second contour, a pool-cooler (120 м3), cooling tower, heat-exchanger, water pumps, pipes, hoses, is included in that. Control of water in knots and systems of cyclotron takes place automatically by means of sensors that are on the exits of chains of cooling of knots of cyclotron. A regular bar of control of channel of water is in other apartment from a stand, that complicates the rapid reacting on defects in the system of cooling. For the improvement of control at work of the system of cooling, there was the worked out chart of conclusion of information from the bar of control after the presence of water on a display to the duty operator. In the process of exploitation of the systems of cooling of cyclotron the distilled water loses the isolating properties through the processes of oxidization of materials of pipes and hoses, her conductivity that results in electric hasps on a plate in the system of leadingout of bunch increases, and also to the large errors of determination of current of bunch on the testers of cyclotron.With the purpose of reduction to the amount of hasps on a baffle plate and currents of source in the chains of measuring of current in the testers of cyclotron the cooling volumes charts of cooling of baffle plate and measuring chains of bunch on the testers were separated from the general volume of cooling. For this purpose there was the worked out chart of cooling of these knots with the use of autonomous capacity by volume of about 2 м3 and additional pamp. The distilled water in this capacity cools down the channel of water second to the contour and by an additional ventilator. For termostabilization of water first it is necessary to the contour, that temperature of water second to the contour was in a necessary range. It is arrived at by the management of work of cooling tower (including-shutdown of pump of cooling tower, including-shutdown of cooling ventilator). A cooling tower is located out of building of cyclotron, volume, for termostabilization of water first to the contour the automatic system of including-exception of work of cooling tower and her ventilator is created on the basis of these sensors of temperature of water on the exit of the first contour.
