Development of high current 201.25 MHz deiteron RFQ accelerator

The beam dynamics for a 201.25MHz 50mA 2.0MeV Deuteron RPQ accelerator with duty cycle of 10% lias been further improved by using equipartitioned method. The RPQ structure, mechanical design, thermal analysis and its cooling method have been investigated. The timing of Rf cavity for the field and other parameters has been simulated. A new developed ECR ion source and its setup have been completed and tested. The LEBT for the injection of RFQ is under the construction, and the HEBT at RPQ exit for the further applications has been designed and to be constructed in the near future. All the development results will be presented in this paper.EI
