This project will construct and test a new piston-                         high- pressure system which will allow routine operation at                     pressures of 60-100 kilobars. The design is simple and the                      apparatus small, requiring one 600 ton and one 200 ton hydraulic                ram for a standard one-half inch diameter piston. The increase in               operating pressure will be achieved by the use of a sintered                    diamond in conjunction with a segmented girdle support for the                  core.  There is a critical need for direct experimental                         investigation of the melting relations and other phase changes in               the Earth's mantle at pressures in the 60-100 kilobar range. Some               of this need can be satisfied by the new technology of multi-anvil              high pressure systems, but such instrumentation is extremely                    expensive and this project offers an attractive alternative.
