Abstract

The design and construction status of the Radio Frequency Quadrupole (RFQ) accelerator for the Compact Pulsed Hadron Source (CPHS) at Tsinghua University is presented. The RFQ will accelerate protons from 50 keV to 3 MeV, with the RF frequency of 325 MHz. The total length of the RFQ cavity is about 3 m with the transmission rate of 97.2% predicted by PARMTEQM. Fine machining of the RFQ cavity was completed in July, 2011. The brazing of the vanes, the flanges and the cooling pipes has been finished in September, 2011.

Abstract

The Compact Pulsed Hadron Source (CPHS) project that was launched in September 2009 at Tsinghua University has reached a first commissioning stage in conjunction with on-going activities to fulfill the eventual design goal of a ∼10 13 n/s epithermal-to-cold neutron yield for education, instrumentation development, and industrial applications. Here, we report the latest progress on the design, fabrication, engineering of the 13 MeV/16 kW proton accelerator system, the neutron target station and neutron beamlines, especially regarding the successful delivery of the first 3-MeV proton beam and the realization of the first neutron generation in 2013.
