Construction of user facilities for the proton beam utilization of PEFP

The PEFP (Proton Engineering Frontier Project) was approved by the Korean government under its 21C Frontier R&D Program last year. Final goals of this project are construction of 100 MeV proton linear accelerator, development of beam utilization technologies, and promotion of related industrial technologies. Its major beam utilization areas are new genetic resource development, simulating space radiation environment, SOI(Silicon On Insulator) wafer development using ion-cut technology, and fast switching power semiconductor development. In addition, there are several small research projects concerned with basic science and nuclear physics. In the PEFP, 20 MeV proton beam will be supplied to the users for their experiments from the middle of 2007. This paper contains the conceptual design of user facilities and the construction results of 6 MeV proton beam test facility for pilot studies of the proton beam utilization experiments in the PEFP.
