CONSTRUCTION OF A HIGH CURRENT RFQ FOR ADS STUDY

A high current proton RFQ accelerator has been constructed in China for the basic study of Accelerator Driven Subcritical System. The ADS project is supported by a national program and aimed at the development of clean nuclear energy to meet of the rapid growth of the nuclear power plants in China. The 3.5MeV RFQ accelerator has been fabricated and installed. The beam commissioning with an ECR ion source showed a nice performance of the RFQ with a transmission rate about 92% in the initial test at an injection current of 44mA. This paper presents the recent progress in the construction and commissioning of the RFQ accelerator.
