A Fiber-Optic Thermal Detector of Unconfined Alpha Particles

摘要

A prototype thermal detector intended for measuring spectra and profiles of energetic particles and based on a multifoil thermal detector was tested. Three types of absorbing films were tested: nickel foil, diamond-like carbon (DLC) film, and epitaxial CVD diamond film. A fiber-optic infrared bolometer was used as a sensing element.
