Cryocooler-based cryostat with integrated DAC.

This turn-key low temperature and high pressure diamond anvil cell system is extremely simple to use.   The nominal temperature range is about 10 K up to 325 K, although lower temperatures are achievable.

This is essentially a bench-top cryostat and high pressure system, which is ideal for scattering as well as optical work. 
The second stage cold finger comes with a 38mm diameter copper sample mount, 50 ohm control heater, and  silicon diode temperature sensor.   

A special large-diameter optical radiation shield mounted on first stage is also included.   The standard optical vacuum shroud is four (4) 41.4mm diameter clear view windows.  Various windows materials are possible, such as fused silica and mylar, for example.

The cryostat’s instrumentation skirt includes one 10-pin electrical feedthrough for heater and temperature sensors, one o-ring compression seal port, one blank feedthrough port, evacuation valve and safety pressure relief valve.

A special sample holder to fit either Bragg-LT(G) or OmniDAC-LT cells and integrated gas line to enable gas membrane DAC operation are also included.  Naturally, other cells from our range may be accommodated.

Options for the Diacell® CCS-DAC System include:
♦  An integrated Optiprexx system for ruby fluorescence manometry at low temperatures, including laser, transfer optics, spectrometer and fibre optic.
♦  A model 335 single loop temperature controller with cable to cryostat.
