The measurement of gamma heating in a fusion blanket test assembly

The problem of gamma-heating measurements in a mixed gamma and neutron field is considered. Theoretical background is provided, and current work is reviewed. An experimental system for gamma-heating measurements has been designed and built. Techniques for calibration and neutron-signal rejection have been developed and examined. An experiment designed to test the applicability of the developed techniques has been built. Numerical modeling of the experiment is planned. It is hoped that by comparing calculated to experimental results, a clear picture of gamma heating in a mixed gamma and neutron environment can be obtained.<>
