A 13 MHz - normal conducting cavity for an rf implanter has been successfully developed at PEFP (Proton Engineering Frontier Project). It consists of an inductive coil, accelerating electrodes and a ground electrode for the inductor. Quality factor of 2074 and critical coupling were achieved at resonant frequency of 12.658 MHz. Rf power of 1 kW was forwarded to the cavity without any spark in the cavity. Beam test was then carried out with a 27 keV helium beam generated from a Duoplasmatron ion source. The results showed that the helium beam was accelerated to final energy of 120 keV with energy spread of 1%. Detail experiments and results are addressed in this presentation.

The Proton Engineering Frontier Project (PEFP) is developing a 100-MeV high-duty-factor proton linac, which consists of a 50-keV microwave ion source, a 3-MeV radio frequency quadrupole, a 100-MeV drift tube linac, a 20-MeV beam transport line, and a 100-MeV beam transport line. It will supply proton beams of 20-MeV and 100-MeV with peak current of 20 mA to users for proton beam applications. The beam duty factor will be 24% and 8% respectively. The 20-MeV front-end accelerator has been installed and operated at the KAERI Daejeon test stand for user service, and the rest part of the accelerator has been fabricated and will be installed at the new site of Gyeongju City in 2011. The detailed status of the 100-MeV proton linac will be presented.
