| TUPOY015 | Design of Electron Gun and S-Band Structure for Medical Electron Linear Accelerator | 1930 |
|
||
| Linear accelerator technology has been widely utilized for cancer treatment in hospital. This radiotherapy utilizes an accelerated electron beam to create the x-ray beam. The idea to fabricate the prototype of medical electron linac with low cost for domestic use in Thailand was proposed and the budget has been granted. In the first phase, the electron beam energy of the machine will be 6 MeV or equivalent to x-ray energy of 6 MV. The electron gun is a diode type for the simple and low cost fabrication. The design and simulation study of diode gun will be presented together with an analysis of an electron beam in this gun. The S-Band 6 MeV side-coupled RF cavity has been designed to be the accelerating structure of the machine. The electromagnetic fields of the structure have been studied. The electron behaviour when they traverse this cavity will be studied using a particle tracking code. Progression of the project is also presented. | ||

| TUPOY016 | The Optimized X-ray Target of Electron Linear Accelerator for Radiotherapy | 1933 |
|
||
| The x-ray target in medical electron linear accelerator is an important part in the production of x-ray photon beam. X-ray dose rate is depended on materials and thickness of the target. For the low cost 6 MeV prototype of medical linac in Thailand, this study gives the optimized x-ray target in which the dose rate can be maximized. MCNP simulations were performed during an optimization for a high x-ray dose rate at 1 meter away from the target. Progression of the project is also presented. | ||

| WEPMY002 | SLRI Beam Test Facility Development Project | 2539 |
|

Funding: This work is supported by the National Science and Technology Development Agency (NSTDA) under contract FDA-C0-2558-855-TH. The SLRI Beam Test Facility (SLRI BTF) is a part of the future upgrades of the SLRI accelerator complex. Upon completion, SLRI BTF will be able to produce electron test beams with the number of electrons ranging from a few to several thousand electrons per bunch. The project is divided into three stages based on the complexity of the electron reduction setups. The simple setup for the initial stage has been implemented without any modifications to the current high-energy beam transport line (HBT) while additional elements together with an existing 4-degree dipole are required for the short-term setup in the second stage. For the last stage, a new dedicated transfer line equipped with a high-resolution energy selector will be constructed to direct the electron beam from the HBT beam line to an experimental station. This project aims to provide a defined number of electrons with maximum energy of 1 GeV for calibration and testing of high energy detectors as well as other beam diagnostic instrumentations. |
