<p>A scintillator detector apparatus includes a sandwich of fibers disposed in a spaced apart pattern for detecting one form of radiation while enabling another form of radiation to pass through open portions between the fibers along with a thin film attached to or proximate to the fibers for detecting the another form of radiation. The thin film is disposed on a plastic substrate which includes a reflecting layer for directed scintillation from the film into the fibers. The fibers scintillate upon interception of, for example, beta particles, which is transmitted to photomultiplier apparatus by the fibers. The fibers are also sensitive to ultraviolet scintillation from the film and it responds thereto to generate scintillation which is also transmitted to the photomultiplier tube. Combinations of the sandwiches may be utilized to formulate time of flight scintillation detectors and the sandwich can be responsive to various types of radiation dependent upon selected fibers and thin films.</p> |
