This report describes all work carried out as part of the High Energy Accelerator Tomography (HEAT) project under the European Commission's programme on Radioactive Waste Management 1990-1994. The primary goal of the project was the development of a non-destructive technique for the generation of tomographic images of highly radioactive objects such as glass monoliths of high level radioactive waste. The technique is based on the measurement of gamma-ray transmissions with electron bremsstrahlung from an electron linear accelerator as the photon source. Section 1 describes the three main phases in the development of the HEAT technique: design, construction and testing of Cerenkov counters, collimators and a bremsstrahlung converter; optimization of counter performance for tomographic measurements; demonstration of HEAT on simulated waste. Section 2 describes the modelling, design testing and construction of the Cerenkov detectors; section 3 describes hardware and software modifications; section 4 describes a collimator system designed and constructed for use with the new detectors; section 5 describes the problems with the BAM linac; section 6 sets out the performance of the whole new Linac driven CT system; and finally in section 7 conclusions are drawn and future applications of the new system outlined.
