At the Materials and Life Science Experimental Facility (MLF) in J-PARC, most of sample environment (SE) such as closed-cycle refrigerator (CCR) is prepared by the instruments individually as the standard SE equipment depending on the experiments carried out at the instrument. This system has advantages that the instrument group can directly contact the users and respond to their request and that the instrument can design its various components to adopt the instrument. On the other hand, several pieces of SE, which are not utilized so frequently but essential, are managed by the SE team. They are commonly used at several instruments in MLF. In these SEs, several cryostats, a high-temperature furnace and a superconducting magnet can be currently used for the inelastic and quasi-elastic neutron scattering experiments. Furthermore, high-pressure experiment using the Paris-Edinburgh press or clamped cell is also being prepared for these experiments.
