PROBLEM TO BE SOLVED: To keep a substance pressurized at 1,000,000 atmospheric pressure or higher in a diamond anvil cell in a high-temperature state of 10,000°C or higher without melting the diamond anvil. SOLUTION: A sample is kept in a high pressure of 1,000,000 atmospheric pressure or higher in a diamond anvil cell. The kinetic energy of ion particles is controlled by controlling a full-range ion accelerator is controlled in a manner that the Bragg peak is conformed with an aimed heating position of the sample. Pulsed ion beam 3 with repeated frequency of about 10 Hz is radiated to the sample to directly heat the sample at 10,000°C or higher. Since the sample is heated instantaneously by the pulsed ion beam, the diamond anvil 1 is not melted. The abruptly heated sample is cooled quickly, so that the sample is put in a stable state at a normal temperature without turning back to the state before the heating. An innovative substance can be synthesized in the ultrahigh pressure and ultrahigh temperature. COPYRIGHT: (C)2010,JPO&INPIT
