The Continuous Wave Deuterium Demonstrator (CWDD) design and status

The design of the Continuous Wave Deuterium Demonstrator (CWDD) and the status of the fabricated hardware is presented. The CWDD is a high brightness, 352 MHz, CW linear accelerator designed to deliver a 7.54 MeV, 80 mA D- beam at a transverse normalized rms emittance of 0.11 π mm-mrad and a longitudinal rms emittance of 0.20 π mm-mrad. End-to-end beam dynamics analysis for nominal and off-design conditions is described. The tuning and predicted operational performance of the as-built device are also discussed. These results all indicate that the present design can meet the output performance specifications in the presence of combined errors at the limits of the specified engineering tolerances. Preliminary injector operations have been conducted at AEA Technologies, Culham Laboratory and at Argonne National Laboratory, where the CWDD is sited. Initial RFQ beam experiments at Argonne are projected for early 1994. DTL installation and commissioning will be completed in 1995
