| Abstract |
We are constructing a linac for development of accelerator components at J-PARC. This linac consists of a H⁻ ion source, a low energy beam transport (LEBT), an radio frequency quadrupole (RFQ) linac, and a diagnostics bean line. The beam energy is 3 MeV, the beam current is 30 mA, and the duty factor is 0.6%, which corresponds to 0.5 kW. The accelerator itself has a capacity of at least 1 kW. However, the beam power is limited by radiation dose, because there are no radiation shields between the accessible area during the operation. The source and LEBT are same as the J-PARC linac's. The RFQ is a used one in the J-PARC linac, called RFQ I. At first, we are planning to conduct experiments of the laser charge exchange development for the transmutation facility. Then, this linac will be used for the development accelerator components such as beam scrapers, bunch shape monitors, laser profile monitors, and so on. We will be able to install new devices into the actual J-PARC linac after the full testing. The development of H⁻ ion source can be carried out at this system, and also RFQ in the future. In this paper, present status of this 3-MeV linac at J-PARC is presented.
