We are developing 1.5 cell SRF (Superconducting RF) 1.3GHz electron gun to realize the generation of high intensity electron beam for compact water purification system. In the first stage, we manufactured Nb 1.5 cell RF gun and tested it at 2K1). Next planned step is to generate Nb3Sn layers with thickness of a few um on the surface of Nb superconducting cavities for 4K operation. Then, we...
The report describes a series of industrial accelerators of the ILU type with energy of 1-10 MeV, with a power of up to 100 kW for irradiating products in the electronic mode and in the X-ray bremsstrahlung mode.
High power electron linear accelerator (linac) is particularly useful and powerful tool for the RI production via photonuclear reaction, which has large cross-section in energy range from 10 MeV to 30 MeV (Giant resonance). For a photonuclear reaction, bremsstrahlung γ-rays is produced by an electron beam irradiating the target materials. At ELPH, we employ an S-band electron linac of which...
Single photon emission computed tomography is a medical diagnostic tool mainly used for cancer surveys. An image of the diseased part can be acquired using 141-keV gamma rays emitted from Tc-99m. Tc-99m has a half-life of 6 h and is the decay product of Mo-99. For long term sustainable production of Mo-99, the accelerator based system seems to be very promising.
The compact energy recovery...
A 70 MeV commercial H- cyclotron system will be used to employ an Isotope Separation On-Line (ISOL) method for the Rare Isotope Science Project (RISP) in Korea. We made a contract with IBA in 2019 for the cyclotron system, and its installation will begin in October 2021. The cyclotron is capable of providing a beam with a current of up to 0.75 mA and has two ports for beam extraction. The beam...
D-BNCT is an accelerator-based BNCT facility in Dongguan, China. The neutrons are generated from a Lithium target bombarded by a proton beam from an intense beam RFQ linac of 3.5MeV. In its initial commission stage, it can provide beam power about 10kW on a solid lithium target. The D-BNCT neutron source now is in routine operation as a BNCT test platform open for national institutes,...
SAMEER has proposed First Heavy Ion Therapy in India in collaboration with Tata Memorial Centre, Mumbai and KEK, Japan. The hadron driver in the proposal is based on a fast cycling induction synchrotron. Its main features are injector free, multi species of ion acceleration capability, fast cycling at 10 Hz repetition rate, energy varying 1 turn fast extraction and energy sweep extraction....
Based on many years of experience in development of silicon-on-insulator (SOI) microdosimeter, the Centre for Medical Radiation Physics, University of Wollongong, has successfully developed a microdosimetric probe which is based on a SOI microdosimeter with 3D micron sized sensitive volumes (SVs) array mimicking dimensions of cells, known as the “MicroPlus-Mushroom” microdosimeters, to address...
Geant4 is a simulation toolkit for radiophysics related to HEP experiments. International collaboration among KEK, CERN, and the other research institutes associated with HEP experiments have developed Geant4 for more than 20 years. Currently, Geant4 has widely been used in various research fields other than HEP experiments. Geant4-Japan group has been focusing on Geant4 application studies...
