| | An accelerator improvement project has been
underway for several years to increase the energy of the
ATLAS heavy ion linac at ANL. A new cryomodule
containing drift-tube-loaded superconducting cavities is
nearing the end of construction, with seven new cavities
complete and ready for clean assembly into the cryostat.
We describe the present status of the project, focusing
particularly on cavity fabrication. Several cost saving
techniques suitable for multi-unit production have been
used, including electric discharge machining (EDM) part
trimming and multi-part electron beam weld (EBW)
fixturing. Subsystem fabrication including couplers, slow
tuners, and VCX fast tuners is also described as are the
clean processing techniques used for particle-free
assembly. | |
