Project summary

Technical approach and methodology:

Technical approach to the fulfillment of submitted project will be based upon the presently available results of scientific researches carried out last years by different teams in the former USSR, generally purposed to military applications. It will be accomplished by the joint team including the most part of their stuff. Further investigations of diamond electric properties are necessary for diamond detector technology modification for peaceful applications. Both already tested and newly developed research methods in conjunctive fields will be used.

Detailed physical analysis and experimental study of diamond band structure, charge carrier energy distributions, transport and transient processes in the crystal volume will be the general purpose at the first stage of work. Modification of already available equipment and designing of additional apparatus for experimental researches will be required. Row diamond materials and wafers classification criteria, selecting and testing procedure ordered to provide high quality detector manufacturing will be developed simultaneously.

On the next stage of work the investigations of junction properties and corresponding technological experiments will be necessary. Detailed calculations of contact and the whole detector structure models will be carried out. This part of work will be closely related to developments, achievements and particular improvements in the detector manufacturing processes. Besides of the experimental research great attention will be paid to theoretical studies.

At the final stage most efforts will be applied to designing and manufacturing of various detectors, units and assemblies with required technical properties, their metrology, calibration and testing in real conditions of usage. A lot of work concerning the optimisation of device configuration, preamplifier circuits and final design can be foreseen. In the case of necessity further researches and developments in diamond technology will be carried out also.

Foreign collaborators:

- Princeton Plasma Physics Laboratory (Princeton, USA)

- Joint European Torus (Culham, UK)

- Japan Atomic Energy Research Institute (Naka, Japan)

- PTW-Freiburg (Freiburg, Germany)

- Loma Linda University Medical Center (Loma Linda, USA)

Foreign collaborators are potentially interested in joint testing and applications of the detectors to be created in the frame of the Project.

Summary of the project objectives:

- detailed physical analysis and experimental study of diamond;

- diamond detectors technology research and development;

- testing and applications of diamond detectors at ISTC Parties experimental facilities.

Expected results:

Advanced diamond and diamond structure crystals technology of UV, soft X-ray, gamma, neutron and other kind radiation detectors would be a perspective result of the project submitted. These detectors can be applied, for example, to the nuclear fusion products researches, nuclear wastes burial-ground dosimetry (at extremely high temperatures and radiation levels), medical microdosimetry.
