Abstract

A temperature-pressure variable system for neutron scattering experiments, so called “Mito system”, was developed several years ago. The Mito system allows us (1) to control pressure up to 10 GPa, and temperature from 80 K to 473 K; (2) to control temperature with very high rate (max. 20 K min<sup>−1</sup>); (3) to control temperature stably (±0.1 K over 100 K, and ±0.3 K below 100 K, approximately). It is particularly noteworthy that pressure can be downloadable to 0 GPa even at 80 K, which is not straightforward for other systems. Here I review the background of previous situation and technical problems of neutron diffraction experiments under non-ambient conditions before the development of Mito system, and also describe how these problems were overcome. Examples of neutron diffraction experiments by using the Mito system, and the currently progressing developments for the Mito system are briefly shown.<br>
