Cooling device for DAC cell

Cooling device for DAC cell  is a DAC cell  embodied in e large copper block, attached to the cold tip of a low vibration closed cycle cryostat systems providing a controlled low temperature vacuum environment, vacuum chamber is it. The cryostat, works on the closed helium circuit. Imdium material is a thin sheet placed for a termic contact from copper block and the cryostat tip. The sample is positioned on the sample holder (DAC cell) in good thermal contact with and surrounded by the vacuum. To change the sample, the cryostat must be warmed at room temperature, the vacuum released and the outer case and radiation shield removed.

A remote control for DAC is necessary to change the pressure inside the sample.

The vacuum chamber provide cryogenic environments for optical measurements for DAC cell. The designs combine the best optical access with the capability to operate in the temperature range 15 to 500 K. Benefits include a wide optical access for light collection measurements. Besides an optimized design provide an excellent optical access and a short space to permit to focalize beam with a objective 20mm WD. The large acceptance angle makes them ideal for light collection measurements (for example Raman studies). Optical measurements that cover a broad range of wavelengths may exceed the transmission band of a particular window material. All windows in the cooling devices are demountable. The present vacuum vessel can accommodate various types of diamond-anvil cells simply by changing the holder or different types of cold unit. High temperatures can be also used. The sample is located into the DAC. Changing the sample simply involves removing the cell, replacing the sample and inserting the cell back into the cryostat. The system can be adjusted in  X-Y-Z with manual or motorized stages how needs require.
