Funding: National Basic Research Program of China (contract No. 2014CB845500) and the 100 Talents Program of the CAS ( No. Y214160BR0) and China Nature Science Foundation (contract No. 11221064). Heavy-Ion Advanced Research Facility (HIAF) is a new project proposed at Institute of Modern Physics (IMP) in China. HIAF project accelerator is composed of intense ion beam sources, injector superconducting LINAC, acceleration and accumulation storage ring, a collection ring and a collider ring. To achieve the ultimate project goal, HIAF accelerator requires the ion source to provide very high intensity of heavy ion beams, such as 1.7 emA 238U34+ with a repetition rate of 5 Hz and pulse length of 0.5 ms. No state-of-the-art ion source can meet the needs. As a baseline of the project, a high performance superconducting ECR ion source, which is designed to be operational at the microwave frequency of 40-60 GHz will be adopted to produce the pulsed beam of interest for the HIAF accelerator. To transport and match the beams from ECR to the downstream RFQ, a low energy beam transport (LEBT) is needed. This paper presents a preliminary design of the LEBT and the beam dynamics in the LEBT. |

THPME025 | Low Power Test of a Hybrid Single Cavity Linac | 3274 |
|
||
We fabricated and assembled a hybrid single cavity (HSC) linac which is formed by combining a radio frequency quadrupole (RFQ) structure and a drift tube (DT) structure into one interdigital-H (IH) cavity. ]. The HSC linac was designed as an injector for a cancer facility and was able to be used as a neutron source for boron neutron capture therapy. The injection method of the HSC linac used a direct plasma injection scheme (DPIS), which is considered to be the only method for accelerating a high current heavy ion beam produced by a laser ion source. The input beam current was designed to be 20 mA, which could be produced by a laser ion source. According to the simulations and calculations, the HSC linac could accelerate a 6-mA C6+, beam which satisfies the particle number criteria for cancer therapy use (108~9 ions/pulse). Details of the measurements and evaluations of the assembled HSC linac, and details of a DPIS test using a laser ion source are reported in this paper. | ||

THPME026 | The R&D Status of SSC-LINAC | 3277 |
|
||
A powerful heavy ion injector SSC-linac is under constructing at IMP in Lanzhou. The continuous wave (CW) 4-rod RFQ operating at 53.667 MHz has been developed as the low beam energy injector linac. The 40Ar8+ ion beam extracted from the ECR ion source was used for the RFQ commissioning. The particle energy 142.8 keV/u and the 198 euA beam current were measured at the exit of RFQ with the 94% transmission. In this paper, the recent R&D progress of the SSC-LINAC including the development of key components and the beam commissioning results are presented. | ||
