Accelerator Cooling-System Design and Economics

This paper is a condensation of an unfinished report on accelerator cooling systems. When published, it will be made available to interested parties. It is based on approximately twenty years experience with a number of accelerators, on materials testing and engineering analysis, and on information obtained from other laboratories. 1. The relative cost of cooling depends on geographic location and atmospheric conditions, on cooling water supply temperature and temperature range, on the cooling method used, and on the degree of cooling-system centralization. 2. The cooling water supply temperature and temperature range affect the operating costs of other accelerator components. 3. Many materials are available for use in low-conductivity water systems. All have limitations.
