    摘要: The invention relates to a diamond radiation probe (10) which is sensitive to ionising radiations. The probe (10) comprises an elongate probe body (14) terminating in a probe head (12). First and second electrodes (18; 20) are carried on the probe head, and mounting means, such as a clamp (32, 40, 42), are provided for mounting a counting diamond (24) between the first and second electrodes. First and second electrically conductive leads (32, 36, 54; 71) extend rearwardly from the respective first and second electrodes through the probe body, and an earth shield (46) is interposed between the first and second leads. The second electrode (20) is disposed rearwardly of the first electrode, and the first and second electrodes are arranged to contact opposite sides of the counting diamond (24). Both the electrodes and the probe head are formed from a material which is near tissue-equivalent. The probe is designed to be used with dosimetry equipment, and is particularly well suited for use in electron beam therapy.

    摘要: A method of producing a composite diamond abrasive compact includes the steps of forming an unbonded assembly comprising a cemented carbide body (10), a layer (18) of catalyst metal on a surface (20) of the carbide body (10), a layer (22) of carbide particles, alone or in admixture with other particles, on the catalyst metal layer, and a layer (24) of diamond particles on the carbide layer (22) and subjecting the unbonded assembly to conditions of elevated temperature and pressure at which diamond is crystallographically stable to form a composite diamond abrasive compact.
