摘要：

A miniaturized detector consisting of three custom built hybrid circuits, a counter and a miniature high voltage power supply was designed to operate with custom synthesized Type Ib diamond crystals as sensors. Thick-film technology was incorporated in the circuit design. With a crystal having a volume of approximately 10 mm3 and containing approximately 60 ppm paramagnetic nitrogen, the detector was capable of measuring gamma-ray dose-rates as low as 7.5-mu Gy h-1. The response characteristic was linear up to 1 cGy h-1.
