Diacell® CryoDAC-Tesla

High magnetic field, Optical Spectroscopy, Pmax = 30 GPa, Tmin = 4K, WD = 11 mm, A = 40°

Diacell® CryoDAC Series

  • The Diacell® CryoDAC-Tesla has a very small core in the form of a cube with 11.5 mm sides, providing optical apertures in the horizontal plane
  • Pressure is applied by clamping the core between two hemicylinders with a combination of left and right hand bolts
  • This DAC is ideal for optical measurements at low temperature and high magnetic field or any other environment where space is at a premium
  • The cell uses small specially designed diamond anvils with 2.00 mm girdle diameter
  • Maximum pressure of up to above 30 GPa may be obtained with the Diacell® CryoDAC-Tesla

SKU: A71000

The Diacell® CryoDAC-Tesla is a very small cell (11.5 mm cube) and was designed for applications that require a diamond anvil cell to operate in a cryostat within a high magnetic field AND with the diamond-diamond axis in the horizontal plane.

The cell is made of BeCu alloy.  Pressure is applied by clamping the cell itself between two copper hemicylinders that are driven by a pair of left-hand/right-hand bolts.


The CryoDAC-Tesla has been designed for optical use under high-magnetic fields and at low & ultra-low temperatures.  We are also able to supply the CryoDAC-Tesla in smaller diameter versions.  Please contact us if this is what you require.

What is the maximum pressure I can achieve with the CryoDAC-Tesla and a given culet size?

Culet size (µm) 200 300 400 500 600 800 1000
Pmax (GPa) (*) N/A 48 31 20 14 8 5

(*) The Pmax values are only indicative. The maximum pressure achievable with a DAC is influenced by many others experimental parameters, like the gasket characteristics (material, thickness and hole size) or the pressure transmitting medium.
