PAL-EUV Vacuum System | |
|
||
| The PAL-EUV accelerator consists of a linear accelerator, booster, and storage-ring, including an injector. The electron beam generated by the injector laser is accelerated to 20 MeV in the linear accelerator, then its energy is raised to 400 MeV in the booster before being injected into the storage-ring. The electron beam injected into the storage-ring emits the photons used in the beamline as it passes through the insertion device. All vacuum devices, chambers, and supports for EUV have been manufactured, and individual vacuum leak tests have been completed for both the chambers and the vacuum devices. Currently, all vacuum devices and supports have been installed. Additionally, based on vacuum simulation results, vacuum components such as ion pumps, vacuum gauges, and vacuum valves have been positioned and the required vacuum levels for each section have been satisfied. Specifically, Baking and NEG activation procedures were performed to reach the required vacuum levels for storage-ring, thus achieving the vacuum level required for the EUV accelerator | ||

Development of Advanced Mirror Adjustment Device for Multipurpose Synchrotron Radiation | |
|
||
| The Pohang Accelerator Laboratory’s PLS-II beamline currently utilizes three types of mirror adjustment devices, which have been developed and in use for several years. Based on the experience gained from the development and production of these mirror adjustment devices, a new type of mirror adjustment device is being developed for the Multi-Purpose Synchrotron Radiation Accelerator (4GSR) beamline under construction in Ochang, Chungcheongbuk-do. The types of mirror adjustment devices are categorized as the KB Mirror System, Bender Mirror System, and Mirror System. In the development of the mirror adjustment device, the design should aim to minimize the deformation of the mirror in the Mirror Mounting process. Additionally, efforts are being made to design the mirror cooling system to maximize cooling efficiency, and various tests are being conducted to improve the mechanical stability and address vibration issues in the Mirror Manipulator structure. The development of the mirror adjustment device aims to upgrade its performance and successfully install it in the Multi-Purpose Synchrotron Radiation Accelerator beamline. | ||
