摘要：

We developed a new device involving an individual PT controlling system for neutron-scattering experiments available at 010GPa and at 77473K. Thanks to the thermal insulators made of zirconia and glass-fiber-reinforced plastic under the anvils, temperature only around anvils can be controllable with fast heating/cooling rate of<20K/min, and it also allows us to use normal hydraulic oil even at low temperatures, which has much less risk of leaking compared with helium gas. The feasibility test for this system for neutron diffraction experiments for ice VIII shows that the full decompression is established without any technical difficulty, which used to be not straightforward by the previous systems.
