Commissioning plan for a high-current proton linac

Description: High-power proton linacs (E>500 MeV) are potentially useful for transmutation applications, such as the production of tritium. In production applications, high availability is essential. Achieving high availability requires an accelerator design that simplifies maintenance and accommodates commissioning procedures designed to minimize tune-up time. These are worthwhile goals for any accelerator, but the very high beam powers (170 MW) and heavy beam loading of the Accelerator Production of Tritium (APT) linac introduce significant new challenges. This paper will describe the commissioning plan, as developed to date.

Summary of evaporative cooling system for the SSC silicon tracker

Description: An evaporative cooling system has been developed for the Superconducting Supercollider (SSC) Solenoidal Detector Collaboration (SDC) and the Gamma, Electron and Muon Detector (GEM) silicon tracker electronics. The system operated on the principles of the heat pipe; specifically, evaporation at near vapor-liquid equilibrium without the presence of noncondensible gases, and with a capillary media used to distribute the working fluid. The system used butane as a working fluid for operation at O{degrees}C and 1 atm. pressure. This paper summarizes the evolution of the system design, emphasizing key developments that may be useful for further work. Results of the system performance as of the close-of-effort are presented. A brief summary of results of experiments using a pumped single-phase cooling system are also presented.
