Low Temperature

D'Anvils low-temperature high pressure system is comprised of a LHe flow cryostat made by Janis corporation and our mini-Mighty Opposing- Plates or Piston-Cylinder DAC's reaching temperatures as low as 4 K and pressures beyond 100 GPa.

The ST500 flow cryostat is very versatile and can accommodate a myriad number of studies starting from all optical spectroscoy methods such as Raman, Infra-Red, Resistivity, conventional Mössbauer spectroscopy, Resistivity, etc. and all synchrotron-base applications. The system is based on the ST-500 flow cryostat with nominal vibrations not exceeding ± 15 nm, He consumption of ~ 1 l/hr at 5K(LHe) and 0.1 l/h at 80 K (LN2) and operates in the 3.5 - 475 K range.


Narrowing of Raman lines upon cooling (PbZrTiO3 at 11 GPa)

The low-weight mini-Mighty mighty-mouse1 diamond anvil cells (10-14 grams) are integrated into the cryogenic system allowing for fast cooling- and warming-periods.
