Facilities

High Pressure Devices:

Piston-Cylinder Apparatus:

This is the original Boyd-England hydraulic press with 500-tons capacity. It adopts the conventional 1/2" and 3/4" piston-cylinder cell assemblies. Experiments can be performed at pressures up to 3 GPa and over 2000 ˚C. Contact Person: Yingwei Fei, Location: Research Building R-G25, Restrictions: Special Training Required.

Multi Anvil Devices:

Blue Press

It is an 800-ton hydraulic press. The design of the multi-anvil device consists of a retaining ring which housed six removable push wedges transmit the uniaxial compressive force of the hydraulic ram onto the faces of a cube that is assembled from eight separate tungsten-carbide (WC) cubes. The pressure chamber is designed to adopt 1" WC cube. Experiments can be performed at pressures up to 25 GPa and over 2000 ˚C.

Green Press

It is a 1500-ton hydraulic press. The design of the multi-anvil device consists of a retaining ring which housed six removable push wedges transmit the uniaxial compressive force of the hydraulic ram onto the faces of a cube that is assembled from eight separate tungsten-carbide (WC) cubes. The pressure chamber is designed to adopt 1" WC cube. Experiments can be performed at pressures up to 27 GPa and over 2000 ˚C.

Orange Press

It is a 1500-ton hydraulic press, donated by Dean Presnall. The multi-anvil device consists of two split retaining rings which housed three push wedges in the top and bottom rings. The pressure chamber is designed to adopt 32-mm WC cube. Experiments can be performed at pressures up to 27 GPa and over 2000 ˚C.

The pressure chamber is designed to adopt 32-mm WC cube. Experiments can be performed at pressures up to 27 GPa and over 2000 ˚C.Contact Person: Yingwei Fei, Location:Research Building R-G25, Restrictions:Special Training Required.

Diamond Anvil Cells:

Symmetric Cells for Double Sided Laser Heating

Over 40 symmetric cells are capable of generating pressure to 200 GPa routinely. Experiments are conducted at synchrotron facilities at APS and ESRF.

Externally Heated DACs

Uniform, stable temperature is achieved by using small wire heater around the diamond or large heater around the cylinder. Ceramic seats are also used for efficient heat. Simultaneous pressure and temperature up to 120 GPa and 1100 K can be routinely achieved.

Internally Heated DACs

Metallic sample such as iron used as heater and sample in the internally heated DAC, that is capable of generate stable temperatures up to 100 GPa and 2000 K.
