Preface

The first Symposium on Semiconductors for Room-Temperature Radiation DetectorApplications was held at the 1993 MRS Spring Meeting in San Francisco, California.The purpose of the symposium was to provide a forum for presenting and evaluatingthe most recent results on semiconductor radiation detectors for utilization in the energyrange of a few eV to 1 MeV. The primary emphasis of the papers was on developingx-ray and gamma-ray detectors which combine the advantages of room temperatureoperation with the excellent energy resolution of cryogenically cooled spectrometers.By eliminating the cryogen, new radiation-sensing instruments can be manufactured thatare portable, easy to operate, and relatively maintenance-free.

The symposium was organized into technical sessions on mercuric iodide, cadmiumtelluride, diamond, cadmium zinc telluride, silicon, new detector materials, and deviceapplications. The discussion on device performance indicated that the quality of room-temperature semiconductor x-ray and gamma-ray detectors now meet the specificationsrequired for several applications in spectroscopy, environmental monitoring, mineralexploration, medical instrumentation, imaging, space, and industrial quality control.Progress was also demonstrated in the processing of the electronic pulses to improve theenergy resolution of the detectors, and in the availability of compact circuits to allowpackaging of field instruments which have significantly less weight compared toconventional technology. New results were reported on the relationships betweenmaterial properties and detector quality, and on improved techniques for purification,crystal growth, and processing technology. These measurements generated confidencethat continued advances in the performance of room-temperature semiconductordetectors and an expanded commercial market for these detectors are forthcoming.

The symposium was well attended, and the international participation was especiallystrong. One hundred and six presentations representing work from twenty one countrieswere given orally or as posters. This proceedings volume contains seventy-six peer-reviewed papers. The symposium organizers hope that it will serve as an importantupdate on the status of the technology and as a useful reference source for othersworking in the field.
