Nakajima, Kenji; Kawakita, Yukinobu; Ito, Shinichi*; Abe, Jun*; Aizawa, Kazuya; Aoki, Hiroyuki; Endo, Hitoshi*; Fujita, Masaki*; Funakoshi, Kenichi*; Gong, W.*; et al.

Quantum Beam Science (Internet), 1(3), p.9_1 - 9_59, 2017/12

The neutron instruments suite, installed at the spallation neutron source of the Materials and Life Science Experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), is reviewed. MLF has 23 neutron beam ports and 21 instruments are in operation for user programs or are under commissioning. A unique and challenging instrumental suite in MLF has been realized via combination of a high-performance neutron source, optimized for neutron scattering, and unique instruments using cutting-edge technologies. All instruments are/will serve in world-leading investigations in a broad range of fields, from fundamental physics to industrial applications. In this review, overviews, characteristic features, and typical applications of the individual instruments are mentioned.

Recent progress in the energy recovery linac project in Japan

Sakanaka, Shogo*; Akemoto, Mitsuo*; Aoto, Tomohiro*; Arakawa, Dai*; Asaoka, Seiji*; Enomoto, Atsushi*; Fukuda, Shigeki*; Furukawa, Kazuro*; Furuya, Takaaki*; Haga, Kaiichi*; et al.

Future synchrotron light source using a 5-GeV energy recovery linac (ERL) is under proposal by our Japanese collaboration team, and we are conducting R&D efforts for that. We are developing high-brightness DC photocathode guns, two types of cryomodules for both injector and main superconducting (SC) linacs, and 1.3 GHz high CW-power RF sources. We are also constructing the Compact ERL (cERL) for demonstrating the recirculation of low-emittance, high-current beams using above-mentioned critical technologies.

Bifunctional phosphonate fiber derived from vinylbiphenyl-grafted polyethylene-coated polypropylene fiber for extremely rapid removal of iron(III)

Jo, Akinori*; Okada, Kenji*; Nakao, Mitsuhiro*; Sugo, Takanobu; Tamada, Masao; Katakai, Akio

Nihon Ion Kokan Gakkai-Shi, 14(Suppl.), p.69 - 72, 2003/00

The titled bifunctional fiber (FVCPS-f) were prepared by treating chloromethylated vinylbiphenyl-grafted polyethylene-coated polypropylene fiber (0.9 denier, length 3.8 cm) with triethyl phosphite, chlorosulfonic acid, and conc. hydrochloric acid, in successive. Phosphorus and sulfur contents of FVCPS-f were 1.8 and 0.7 mmol/g, respectively (acid capacity 4.2 meq/g). Its breakthrough capacity (BC) for Fe(III) gradually decreased with an increase in flow rate of feeds from 20/h to 1000/h in space velocity (SV); for instance, its BC at a SV 1000/h was 0.12 mmol/g, whereas both a commercially available phosphonate resin and a monofunctional phosphonate fiber were not able to give practically meaningful BC at such an extremely high flow rate.
