A hydraulic pressure of 700 bars applied to the jack corresponds to an axial force of 1000 tons.
Pressure is controlled by an electronically controlled screw worm jack.
Noble metal capsules containing the starting material are placed in the hot spot of the furnace. MgO spacers and ceramic insulators are placed around the capsule and the thermocouple. Graphite discs on both the ends of the assembly provide electrical contact with the WC cubes.
