The high-intensity heavy ion accelerator facility is a next-generation advanced heavy-ion accelerator facility built by the Institute of Modern Physics, Chinese Academy of Sciences. The RFQ is designed to provide a continuous wave beam and 2[Formula: see text]mA pulse beam with high-quality longitudinal beam distribution for the injection linear accelerator. Two different designs of aiming to suppress the longitudinal emittance were studied, and the optimized scheme which composed of a three-harmonic pre-buncher and an RFQ accelerator with small longitudinal acceptance was chosen. More emphasis is put on the section between pre-buncher and RFQ, where the space charge effect becomes severe with bunched beam. The optimal design and the analysis are presented in this paper.

Radiotherapy using protons and heavier ions is emerging as an alternative to traditional photon radiotherapy for cancer treatment. Ions have a depth-dose profile that results in high energy deposition at the end of the particle’s path, with a relatively low dosage elsewhere. However, the specifics of ion interactions with cellular biology are not yet fully understood. To study the induced biological effects of the ions on cell cultures, an external beam is required as biological specimens cannot be placed in vacuum. The Heavy Ion Accelerator Facility (HIAF) at the Australian National University hosts accelerators for a wide variety of ion-beam research applications. However, HIAF does not currently have an external beam capability. Here, we present an initial design for a radiobiological research capability at HIAF. A systems engineering approach was used to develop the architecture of the apparatus and determine the feasibility of adapting the current facilities to external beam applications. This effort included ion optics calculations, coupled to a Geant4 simulation, to characterise ion beam transitions through a thin window into the air. The beam spread, intensity distributions, and energy of proton and carbon ions were studied as a function of distance travelled from the window, as well as the effects of alternative window materials and thicknesses. It was determined that the proposed line at the HIAF would be suitable for the desired applications. Overall, this feasibility study lays the foundations of an external beam design, a simulation test framework, and the basis for a grant application for an external beam at the HIAF.

Italic textAbstract. Industrial Streptomyces avermitilis were irradiated by 80 MeV/u 12C6+ ions whith were provided by the Institute of Modern Physics, Chinese Academy of Sciences, Lanzhou Heavy Ion Accelerator. The high titers of mutants were obtained with different doses. The original strains and the high titers of mutants were detected and analyzed by Random Amplified Polymorphic DNA technology (RAPD). The results show that bands could be got from amplify the original strain by 4 primers of 28 primers and the high titers of mutants were amplified by the 4 primers. The amplified products were analysed by Jaccard formula. After 10 Gy, 30 Gy, 40 Gy, 45 Gy, 50 Gy, 70 Gy isodose irradiation, the similarity index were 0.63, 0.75, 0.71, 0.8, 0.61, 0.73. It was confirmed that at the DNA level, not only the high titers strains and the original mutant strain’s DNA were different, but also the high titers of the different mutants’ DNA were different. Therefore, ion implantation method changed the different Streptomyces avermitilis genetic material which promote the importance trace of avermectin biosynthesis changed, and different high titers of Streptomyces avermitilis were obtained.

Water Leakage Detection

HIRFL system is the most advanced Heavy Ion Research Facility in world; to protect its safe operation is the major responsibility of the Institute of Modern Physics, Chinese Academy of Sciences. To process the situation of possible water leakage during the operation of equipments, we developed a water leakage detection system. The system can precisely detect the specific location of water leakage, and visually display on the computer in the control room remotely. The paper describes the theoretical design and practical, and assesses the effect of the field running. It has been successful early warning repeatedly water leaking avoid accidents, ensure the normal operation of the machine, since the system established in 2010.
