We successfully developed a new photomultiplier tube (PMT) with a three-inch diameter, convex-shaped photocathode, R13111. Its prominent features include good performance and ultra-low radioactivity. The convex-shaped photocathode realized a large ph

Metallic nanoparticles of Ag–Pt double-shell on Au-core (Au@Ag@Pt core@multishell NPs) with a hollow-granular shell structure were synthesized by coreduction method, a combination of galvanic replacement reaction with a coreducing agent. Their nano

Radioactive impurities in the detector material have been focused as the serious background in a search for a dark matter. In order to select a pure material which have a low radioactive impurity such as nuclear in uranium-chain and thorium-chain, a

We developed a gas electron multiplier (GEM) that is highly reliable against discharge using a Low Temperature Co-fired Ceramic (LTCC) as an insulating layer (LTCC-GEM). Because LTCC is an inorganic anti-carbonized material, LTCC-GEM is expected to b

An α-ray imaging chamber has been developed based on a gaseous micro-time-projection chamber with a low-α emission μ-PIC in a low radioactivity structure. The detector offers the advantage of position sensitivity, which allows to image the α-ray

An innovative silicon power device (i-Si) made entirely from silicon, which has an extremely low inverter loss beyond that of a conventional IGBT and a pn diode, is proposed. The i-Si is composed of a dual side-gate high-conductivity IGBT (HiGT) thro

We present our recent results on temperature behaviour of magnetization observed in Ni_47Mn_39In_14 Heusler alloys. Three regions can be distinguished in the M-T diagram: (I) low temperature martensitic phase (with the Curie temperature T_CM = 140 K)
