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.

The beam commissioning of the linac for the boron neutron capture therapy of Ibaraki prefecture (i-BNCT) has been started. The accelerator of i-BNCT consists of the 3-MeV RFQ and 8-MeV DTL. The design of RF structure of them is based on the J-PARC linac. After the first demonstration of neutron production on December 2015, significant modifications to the linac were given in order to increase the operation stability and the beam power. The progress of the beam commissioning of the i-BNCT will be presented.
