Sample environment (SE) team at the Materials and Life Science Experimental Facility (MLF) in J-PARC has worked on development and operation of SE equipment and devices. All the members belong to one sub-team at least, such as Cryogenic and magnet, High temperature, High pressure, Soft matter and special environment including Pulse magnet, Hydrogen environment, Light irradiation and He spin filter. Cryostats, a magnet, furnaces, a VX-6-type Paris-Edinburgh press and a prototype of a Spin-Exchange Optical Pumping (SEOP) based He spin filter for polarized neutron beam experiments are in operation. Furthermore, a prototype of compact power supply for a pulsed magnet system is currently developed. In the J-PARC Research Building, several pieces of equipment for softmatter research such as a rheometer and a gas and vapor adsorption measurement instrument have been prepared.

This article describes first the basic aspects of sputtering phenomena based on ion beam - solid interactions, followed by introduction of ion beam sputter deposition (IBSD) method for thin film fabrication. The article further introduces the experimental apparatus for IBSD application, equipped with an ion beam irradiation system for sputter-etching of the substrate surface. It is shown that this method is suitable for fabrication of semiconducting iron silicide film on Si substrate. The experimental results revealed that the obtained thin film is highly-oriented and continuous, forming atomically flat interface between film and the substrate.

Researchers at Japan Atomic Energy Agency (JAEA) have been intensively working on quantum beam technology for the development of proton-conductive membranes for PEMFCs since 2001. My presentation deals with the application of high-energy heavy ion beams from the cyclotron accelerator of Takasaki Ion Accelerators for Advanced Radiation Application (TIARA), JAEA. Our strategic focus is centered on using nano-scale controllability of the ion-beam processing; the membrane preparation involves (1) the irradiation of commercially-available base polymer films with hundreds of MeV ions, (2) graft polymerization of vinyl monomers into electronically-excited parts along the ion trajectory, called latent tracks, and (3) sulfonation of the graft polymers. The resulting membranes were compared with those prepared by the conventional -ray-induced grafting in terms of membrane nanostructures, proton conductivity, and other properties.

Takasaki advanced radiation research institute is a preeminent institute in the world since three irradiation research facilities of ion beam, electron beam, X-ray can be available. Industrial applications in the field of environment, energy, health care, and biotechnology have been researched for half over a century by means of radiation processing or quantum beam technology. We will intend to pioneer newly expected areas from society and aim at the technology transfer of our technology to end-users.

We have a strong motivation to pursue the possibility of using ion beam technology for the creation of nano-structured catalytic materials and their electrochemical device applications. My talk includes (1) the preparation of noble-metal nanoparticles in a glassy carbon (GC) substrate by the metal-ion implantation method, (2) heavy-ion-induced lattice defects in the GC substrate and their effect on the oxygen reduction reaction activity of the deposited platinum nanoparticles, and (3) the formation of polymer nanostructures and their potential as a catalyst support.

We have developed a high average power picosecond laser system dedicated to intense terahertz (THz) pulse generation. The system is a chirped pulse amplification laser equipping with a Yb:YAG thin-disk amplifier. The Yb:YAG thin-disk regenerative amplifier at room temperature provides pulses with energy over 10 mJ and spectral bandwidth of 1.2 nm at a repetition rate of 1 kHz. In a pulse compressor, the laser pulse is compressed to be 1.3 ps. By employing this picosecond pulse as a pump source, THz pulses at the center frequency of 0.3 THz with energy over a few microjoules have been generated at 1 kHz repetition rate by the optical rectification in Mg-LiNbO crystal.

It is believed that spin triplet superconductivity is realized in SrRuO. However, there are some objections for the spin triplet superconductivity. The spin triplet superconductivity is suggested mainly from NMR Knight shift measurements. Different form NMR, muon gives us the information completely inside the specimen. In our presentation, we report on the muon Knight shift measurement in SrRuO.

【課題】荷電粒子ビームとの間の相互作用によるプローブの熱負荷が大きな場合であっても、荷電粒子ビームのビームプロファイルを安定して測定する。 【解決手段】ダクト20の内部を紙面垂直方向上向き又は下向きに荷電粒子ビームのバンチBが通過する。このバンチBがビームプロファイルの測定対象となる。ここでは、導電性のプローブ10A、10Bが用いられており、ビーム照射時において各々に誘起される電流が測定可能とされる。これによって、荷電粒子ビームの横方向(X方向、Y方向)のビームプロファイルが測定される。ダクト20よりも左側には、縦方向のビームプロファイルの測定のために、コリメータ30、RFデフレクタ電極40、コリメータ50、電子検出器60、偏向電磁石70が設けられている。プローブ10A、10Bは、高配向性グラファイトで構成される。
