Sample environments in Japan Atomic Energy Agency

Kaneko, Koji   

There exist two major neutron sources, steady reactor source JRR-3, and a 1MW pulsed neutron source J-PARC, at the same site in Tokai, Japan. JRR-3 is stably in operation for last two decades. In total, more than 30 instruments are run by Japan Atomic Energy Agency (JAEA) and university groups. We will give a brief summary on sample environment, such as high-field magnet, low temperature apparatus, pressure cell and so on, in JRR-3. Finally, we also introduce a new superconducting magnet, and a time-of-flight single crystal diffractometer aiming for structural analysis under extreme condition in J-PARC. This new diffractomator is under construction and will be received the first beam in next summer.
