The vacuum system for the APT/LEDA/CCDTL (Accelerator Production of Tritium/ Low Energy Demonstration Accelerator/Coupled-Cavity Drift Tube Linac) Hot Model has been installed and is currently operating at Los Alamos National Laboratory (LANL). The Hot Model has been built to test a new concept in accelerator technology. The vacuum system was designed and partially assembled and then shipped to LANL for final assembly and installation on the APT/LEDA/CCDTL. The system was designed for both flexibility and low cost. Simple outgassing and conduction models were used to predict pumping needs. This design contains almost no custom parts, which allows for quick and inexpensive changes as needed. The system consists of three pumping stages: roughing, turbomolecular, and ion and utilizes all four of the available ports on the Hot Model. This has allowed the system to reach a better level of vacuum than the originally anticipated need. @FootnoteText@ Work performed at AlliedSignal FM&T which is Operated for the United States Department of Energy under Contract No. DE-ACO4-76-DP00613.
