The subject of the workshop was the Gallium Arsenide and related compounds devices for Physics research and applications. The topics were the GaAs detectors for the experimental apparatus, the characterisation of the materials and the detectors, the GaAs electronics and optoelectronics, the radiation hardness and the x-ray detectors for x-ray imaging in medical applications. The purpose of the workshop was to discuss the status of the art of these fields in view of the construction of devices for the stringent demands imposed by the future Physics experiments and the applications in term of speed and radiation hardness.

The 4th San Miniato Topical Seminar on “The Standard Model and Just Beyond” was a continuation of the meetings held in 1985, 1987 and 1991, and covered essentially similar topics. The program focused on reviews of the present experimental progress in precise electroweak and QCD tests, heavy flavour physics (particularly mixing) and the search for new particles. The emphasis was on the most recent results coming from the large statistics data samples collected at LEP, other e+e- machines, hadron colliders and fixed target experiments. The present status of the theory was reviewed and one session was dedicated to the discussion of future plans and physics issues.

This book makes an assessment of the state of the art regarding a new technology, GaAs, which will eventually become vital to construction of the apparatus for high energy physics at future accelerators.
