title: Use of ferroelectric-crystal detectors for electron dosimetry.
abstract: A ferroelectric detector system was designed for measurement of dose rate in high-energy electron beams. It was found that a simple lead zirconate-titanate ceramic responds reproducibly to a chopped electron beam by ferroelectric conversion of the resulting pulsed temperature rise to a proportional output voltage. Response as a function of dose rate is linear, the rate of response being a function of incident energy. As a calorimetric dose-rate meter the detector is responsive with response improving as energy is reduced. The detector can be used over a broad range of energies not usually accessible with a single detector.
