A 20 MeV proton accelerator has been developed by Proton Engineering Frontier Project (PEFP). The accelerator consists of a 50 keV proton injector, a 3 MeV radio frequency quadrupole (RFQ) and a 20 MeV DTL (Drift Tube Linac). The preliminary test is being performed at KAERI (Korea Atomic Energy Research Institute) site. A pulsed proton beam is extracted from the proton injector by switching the high voltage power supply of the ion source. The beam transmission rate through the RFQ was measured with respect to the vane voltage to set the operating point. The 20 MeV DTL consists of four tanks and the beam transmission characteristics have been checked for various parameters. In this paper, a test stand for a 20 MeV accelerator at KAERI site is introduced and the test results are discussed.
