摘要:

We describe a cryostat for neutron diffraction experiments under pressure of 40 kilobar at 4.2–300 K. In this device liquid nitrogen is not used to cool the thermal screens. The pressure is transmitted by columns cooled only by helium boil‐off vapor. One of them can move freely over a range of several centimeters. The liquid helium consumption at 4.2 K is 0.7 liter/h.
