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

Description
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.
Applications
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.

FAQs
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.
