| MOPTS079 | Design of 1.5 GeV Compact Storage Ring for the EUV and Soft X-rays | 1028 |
|
||
| Recently, there has been discussions about the need for the next-generation synchrotron light source facility in Korea. The facility in consideration is composed of a super-conducting linear accelerator for the injector, a storage ring for the EUV and soft X-rays, and a main storage ring for hard X-rays. In this study, design concepts of the soft X-ray storage ring is presented. To effectively utilize the small space allocated for the soft X-ray storage ring, a compact storage ring is taken into account. The compact storage ring is a synchrotron accelerator of which diameter is shorter than the length of injector beamline. In this paper, we report design concepts and optimization of the compact storage ring for the EUV and soft X-ray users. The lattice of the storage ring is modelled by utilizing ELEGANT simulation code to optimize beam parameters and performance of the ring. | ||

| WEPRB055 | Design of 3 MeV S-band Electron Linac Structure With 2.5 Bunching Cells | 2934 |

Funding: UST (University of Science and Technology), KAERI (Korea Atomic Energy Research Institute) The Korea Atomic Energy Research Institute (KAERI) has been designing several 3 MeV S-band RF electron linear accelerators (linacs) for non-destructive testing. Until now, the bunching cell of the linac has a full-cell geometry. However, to maximize the acceleration of electrons after emission from the electron gun, the geometry of the first bunching cell is modified from a full-cell to a half cell. To accelerate electron beams more gently, recently, we increased the total number of bunching cells from 1.5 to 2.5. In this paper, we describe design concepts and detailed optimization processes of a 3 MeV linac with the 2.5 bunching cells to optimize RF parameters such as the quality factor, resonance frequency, and uniformity of electric field distribution along the linac. Lastly, we will discuss the application of 3 MeV linac. |

| THPMP021 | X-ray Dose Rate of 6/4 MeV European S-band Linac Structure for Industrial Application at RTX | 3494 |
|
||
| Recently, RTX has been developing a 6/4 MeV European S-band (= 2998 MHz) industrial linac by using a magnetron with a low RF power of about 3 MW for container inspection system (CIS). Its accelerating structure is designed to operate in π/2 mode by coupling 6 accelerating cells together through 5 side-coupled cells. In CIS, high dose rate X-rays from MeV-energy electron beam has been used to detect the possible presence of contrabands in cargoes or truck containers. To determine a dose rate output, the X-ray dose rate can be simulated by using FLUKA Monte Carlo simulation. The aim of this work was to study the effects of thickness of X-ray target on dose rate as well as X-ray dose map at 1.0 m away from the X-ray target. This study gives the thickness of target in which the dose rate can be highest and electron beam current can be lowest. | ||
