	Funding: This paper is based on results obtained from Innovative Structural Materials R&D Project commissioned by the New Energy and Industrial Technology Development Organization(NEDO). Neutrons are a powerful probe of structural materials due to their high penetration. As part of the Innovative Structural Materials R&D project funded by the New Energy and Industrial Technology Development Organization (NEDO), the Innovative Structural Materials Association (ISMA) is developing a dedicated, compact electron-accelerator based neutron source at the National Institute of Advanced Industrial Science and Technology (AIST) in Tsukuba, Japan, for the characterization of structural materials. The accelerator is designed to have a maximum electron beam power of 10 kW (~36 MeV and ~275 mA), which will be incident on a water-cooled Ta target. The electron beam will have a maximum pulse length of around 10 μs at a repetition rate of 100 Hz. Neutrons produced through photo-nuclear reactions will be cooled by a decoupled solid methane moderator. Using this pulsed, low-energy neutron beam we plan to perform various imaging spectroscopies of structural materials including Bragg-edge imaging. In this contribution we will describe the dedicated neutron source in more detail, with particular emphasis on the electron accelerator.

	An inter-digital H-mode (IH) drift-tube linac (DTL) is developed for a low velocity part in a muon linac at the J-PARC E34 experiment. It will accelerate muons from v/c = 0.08 to 0.28 at an operational frequency of 324 MHz. In order to achieve higher acceleration efficiency and make cost lower, an alternative phase focusing (APF) scheme is adopted. A prototype with 6 cells of 0.45 m length was manufactured. The prototype accelerates muons from v/c = 0.08 to 0.15 stage. We conducted frequency measurement and bead-pull measurement as a low-power measurement, in order to evaluate the prototype product. In this paper, the results of the low-power measurement for prototype cavity will be presented.
