Optical and X-ray Spectroscopy, Pmax = 100 GPa, T = 300 K, WD = 17 mm, A = 60°

The high pressure in the Diacell® SymmDAC 60 is achieved by the means of two pairs of left-hand/right-hand bolts, for pressures up to 100 GPa
The Diacell® SymmDAC 60 enables either side to be used for collection or for introduction of electromagnetic beams (x-rays, laser, visible or infrared light)
The complex gasket-loading process is facilitated by an easy access to the piston side anvil and its associated gasket holder
The Diacell® SymmDAC 60 may also be manufactured in BeCu, to be compatible with magnetic field environments
A 27 mm height alternative is available. The SymmDAC 100 is fitted with 4.00 mm - 80° Boehler- Almax diamond anvils design and provides 100° aperture on both side

Description

Diacell® SymmDAC 60 is a piston cylinder compact and symmetrical diamond anvil cell suitable for optical or X-ray measurements. Diacell® SymmDAC 60 enables either side to be used for both excitation (optical or X-ray) or collection of emitted light or diffraction patterns.
The pressure mechanism is the screw driven one. The pressure is applied by mean of 4 screws, two left-handed and two right-handed screws working in conjunction with superposed Belleville springs. This combination will help the user to apply the load in a more controlled manner.

The Diacell® SymmDAC 60 is fitted as standard with 2.50 mm Diacell® design diamond anvils that are fitted in anvil rings. But this DAC can also be used with Standard design diamond anvils that can be glued directly on the support plates.

The Diacell® SymmDAC 60 can also be adapted with lateral slots on the piston and cylinder. These are made so that the user could accommodate wires for electrical wires used to do transport measurements.

A low temperature and a non-magnetic version of the SymmDAC 60 is also available. The main difference with the standard version is the DAC body material (BeCu) and the support seats for the diamond anvils that are from tungsten carbide with 6% Ni. These later one will have a lower magnetic background than the regular WC support seats.

FAQs

What is the maximum pressure I can achieve with the SymmDAC 60 and a given culet size?

Culet size (µm)	200	300	400	500	600	800	1000
Pmax (GPa) (*)	N/A	64	41	27	18	10	7

(*) 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.
