| PEFP (Proton Engineering Frontier Project) 20 MeV proton accelerator has been installed and tested at KAERI (Korea Atomic Energy Research Institute) site. After the radiation license was issued, some parts were modified to increase a beam current above 1mA. Both an ion source and a LEBT (Low Energy Beam Transport) were modified for better matching of the beam into the 3 MeV RFQ. The field profile of the RFQ was measured to check the dipole field effect. In addition, control mechanisms to improve the RF properties of 20 MeV DTL were newly adopted. In this paper, the modifications of the 20MeV accelerator are summarized and the test results are presented. |
