摘要：

A ferroelectric detector system has been designed for measurement of dose rate in high energy electron beams. We find 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 calorimeter dose rate meter the detector is responsive with response improving as energy is reduced, and may be used over a broad range of energies, not usually accessible with a single detector. © 1990, IEEE
