Project summaryThe project being proposed is the continuation of investigation cycle dealing with processes of medium-energy proton beam interaction with massive targets [1-7]. Part of these investigations have been conducted within framework of ISTC projects ## 157 and 477.
The directivity of investigations has both fundamental and applied character.
The goals of the project being proposed are in the first place, to obtain experimental material to substantiate models that lie at the heart of computational codes of HETC, LAHET, NMTC (JAERI), MARS type, etc.; in the second place, experimental and theoretical study of different aspects of proton beam interaction with targets intended for use in promising power reactor facilities.
The technical approach assumes performing experiments on studying heat deposition and generation of secondary particles in cylindrical targets bombarded by proton beam with energy of 0.8-1.2 GeV and intensity of ~ 1013 protons per pulse. The heat deposition will be studied using thermocouple technique and generation of secondary particles employing activation method and CTOF (Calorimetric Time-Of-Flight)-technique. Development and try-out of the latter technique is one of the goals of the project. Possible materials are Ta or Nb. Analytical and computational study and assessment of such aspects as radiation changes, possible construction diagram and heat transfer in targets of nuclear power facilities as well as simulation of experiments using various codes. In order to perform the project improvement of existing ITEP facility, manufacturing of new targets, new equipment design, existing equipment modernization, partial replacement and upgrade of PC being used at the present time will be necessary.
Continuation of work which will be devoted to studies of the wide range of targets: Nb or Ta, W, Pb, Bi, Cu, Fe, Al, C and Be during stages 4, 5 and 6 with total duration of 3.5 years is proposed by an annex to the present contract.
Potential role of foreign collaborators: Japan Atomic Energy Research Institute (JAERI) and other foreign participants interested in the project will specify target range, take part in experiments and analytical treatment of their results.
