20MeV/100MeV Proton Beam Lines of PEFP User Facility

The main concept of the PEFP proton beam facility is that a high power proton accelerator supplies proton beam to many users simultaneously. This concept can be compared with a facility with many low power proton accelerators for many users. Based on the user demand survey for proton beam applications, we had chosen a facility with a high power accelerator. There are many types of proton accelerator for proton beam applications, such as cyclotron, synchrotron, and linear accelerator. Because the capability of high beam power is the most important feature, we had decided to choose a linear accelerator for the main accelerator of the facility. Proton beams of 100MeV and 20MeV will be extracted and distributed to maximum five users simultaneously by AC magnets with a programmable current power supply. We will control the beam energy stepwise with RF ON/OFF of each DTL tank. To control the beam energy continuously, we will put energy degraders and energy filters in the beam lines for special applications
