Funding: Office of Science - Office of Basic Energy Sciences Abstract Particle Accelerators require significant amounts of water to cool components and devices. Care are and planning are required to maintain these large systems. The purpose here is to provide insight into the operation and maintenance of water systems at the Advanced Photon Source (APS), Argonne National Laboratory. Low Conductivity Water (LCW) systems are integral in the design of particle accelerators. Initial design requirements often change over time to accommodate new requirements. Some of the issues seen over the 23-year operation of the APS are erosion, clogging, and the need for more precise temperature control. Water chemistry, flow velocity, type of control systems and sensors, along with maintenance practices all contribute to successful operation. We will discuss our successes and failures in regards to water quality, temperature stability, reliability and longevity of the system, as well as equipment maintenance and repair. These aspects of water system design and maintenance are all critical to reliable operations of the APS. This document will provide useful information for institutions that intend to design, build, and/or maintain a particle accelerator. Advanced Photon Source, a U.S. Department of Energy (DOE) Office of Science User Facility operated for the DOE Office of Science by Argonne National Laboratory under Contract No. DE-AC02-06CH11357. |
