Album 1(National Laboratory in Japan)

1990-1992 (X-ray diffraction with the He gas closed-cycle cryostat, Daikin Co.)

Sakurai Lab. at Institute for Materials Research (Tohoku Univ., Japan)

This was my first X-ray experiment with Dr. Yosuke Watanabe and Prof. Ken-ichi Ohshima on my undergraduate days.Notice that this is the first low-temperature 4-circle diffractmeter using He gas closed-cycle cryostat in Japan.Temperature cooled down to 15 K.

1990- (X-ray diffraction with the He gas closed-cycle cryostat, Air Products Co.)

BL-4C at Photon Factory (KEK, Japan) The second He gas closed-cycle cryostat was installed by us. The first low-temperature experiment at BL-4C was diffuse scattering measurement from metallic sodium.
Very recently, we improved this guy by attaching the curved graphite and CCD camera to observe the inelastic scattering on quasicrystals. High temperature furnace is also seen.

1991- (X-ray diffraction with the He gas closed-cycle cryostat, Air Products Co.)

Ohshima Lab. at Institute of Applied Physics (Univ. of Tsukuba, Japan)

I set up this low-temperature 4-circle diffractmeter with Kazuo Harada in 1991. My Ph.D thiesis was performed using this guy.(The third low-temperature 4-circle difractmeter using He gas closed-cycle cryostat in Japan)

1992-1994 (Neutron inelastic scattering)

Ponta at JRR-3M (Japan Atomic Energy Research Institute, Japan)

I remember that some earthquake suddenly occured during collecting inelastic scattering data! I was so scared. Of course, the reactor automatically shut down.

1994-1995 (Small angle neutron scattering)

SANS-U at JRR-3M (Japan Atomic Energy Research Institute, Japan)

We developed the alminum containers with Si single crystal windows. Due to this idea, backgrond was reduced 1/20 times less than previous one. See Publications List!!!

2002- (Time of Flight)

FOX at KENS (KEK, Japan)

White neutron + TOF ( Time of Flight )

BL-16A2 at Photon Factory (KEK, Japan)

2003-
BL-1B at Photon Factory (KEK, Japan)
