| THPRO094 | Large Scale Particle Tracking and the Application in the Simulation of the RFQ Accelerator | 3107 |
|

| Large scale particle tracking is important for the design and optimization of the Radio-frequency Quadrupole (RFQ) accelerator. In this paper, we present RFQ simulation results of new parallel software named LOCUS3D, which is developed at Institute of Software, Chinese Academy of Sciences. It is based on Particle-In-Cell method and calculates three-dimensional space charge field by an efficient parallel fast Fourier transform method. A RFQ accelerator in Tsinghua University is simulated by tracking 100 million macro particles. This RFQ is designed to accelerate protons from 50 keV to 3 MeV, with peak beam current of 50 mA. As large number of particles been simulated, more accurate and detailed information have been obtained. | ||

The design, construction and experiments of a cold model of one high-current CW RFQ with ramped inter-vane voltage at Tsinghua University are presented in this paper. The 1-meter-long aluminium cold model is chosen to be the same as the low-energy part of the 3-meter-long RFQ. This cold model will be used mainly for the RFQ field study and education. |

| THPME023 | CPHS Linac Status at Tsinghua University | 3268 |
|
||
|
Funding: Work supported by National Natural Science Foundation of China (Major Research Plan Grant No. 91126003 and 11175096). We present, in this paper, the operation status of the 3 MeV high current proton Linac for the Compact Pulsed Hadron Source (CPHS) at Tsinghua University. Proton beam with the peak current of 30 mA, pulse length of 100 μs and repetition rate of 50 Hz has been delivered to the Beryllium target to produce the neutron since July 2013. The pulse length will be further increased to 500 μs. The proton beam energy is expected to be enhanced to the designed value of 13 MeV after the Drift Tube Linac is ready in 2015. |

| THPME024 | Cooling Design for the FRIB RFQ Cavity at Michigan State University | 3271 |
|
||
|
Funding: Work supported by the Major Research plan of the National Natural Science Foundation of China (Grant No. 91126003) We present, in this paper, the cooling design for the Radio Frequency Quadrupole (RFQ) cavity of the Facility for Rare Isotope Beams (FRIB) at Michigan State University. The locations and radius of the cooling passages are optimized, which exist in the five-meter-long copper cavity, tuners, dipole-mode stabilizing rods and end-plates. A three-dimensional RF, thermal, and structural analysis by ANSYS has been performed to carry out the design and verify that the present design can meet the requirement for water velocity, stress, deformation and frequency shift. |
