摘要： A radiation or neutron detector wherein lateral side light detecting optical fibers prepared from clear optical fibers that are scraped on a lateral side to permit side incidence of fluorescence are used to detect the fluorescence from a phosphor or a scintillator such that the background to gamma-rays is reduced. If desired, the optical fibers may be bent at 90 degrees and guided to a photomultiplier tube in order to reduce the size of the detector. Fabrication and maintenance of the detector can be facilitated by adopting such a design that a detecting block comprising a detection medium and lateral side light detecting optical fibers is separated from a readout block comprising clear optical fibers.

摘要： A 6Li doped glass scintillator sheet with grooves cut at given spacings in horizontal and vertical directions. Bundles of wavelength shifting fibers placed in the vertical grooves and fluorescence reflector buried in the horizontal grooves make a group of detection pixels. Neutron detecting media are provided on the top surface and bundles of wavelength shifting fibers are arranged horizontally on the bottom surface of the scintillator. Fluorescence generated by stimulation with the neutrons entering the detection pixels and with the neutrons incident on the neutron detecting media are detected by the wavelength shifting fibers. The detected fluorescence is converted to electric signals with a multi-channel photomultiplier tube, with pulse signals for simultaneous counting generated from a retriggerable, constant time-duration pulse generator and recorded as time-series data by parallel interfaces. The recorded data are analyzed by the simultaneous counting method to produce a two-dimensional neutron image.

摘要： Radiation doses ranging from a very weak level to a very high instantaneous level can be monitored real-time by, a differential and integral type of radiation measuring apparatus in a convenient and precise manner using a stimulable phosphor as a radiation detecting medium. The radiation detecting portion comprises in planar superposition a bundle of laterally radiating optical fibers, a stimulable phosphor, an optical filter centered at the wavelength of fluorescence, and a-bundle of wavelength shifting optical fibers sensitive to the wavelength of stimulated fluorescence. On the basis of two actions of the stimulable phosphor, one for emitting stimulated fluorescence in proportion to the dose of incident radiation upon illumination with exciting light and the other for emitting prompt fluorescence upon excitation by the incident radiation, the radiation detecting portion selectively detects stimulated fluorescence and prompt fluorescence at specified time intervals. A saturation check circuit monitors the fluorescence detecting mechanism at specified time intervals to see if it is saturated by high-intensity radiation and after it is recovered from saturation, the dose of rapid intense radiation is read with the quantity of exciting light on the stimulable phosphor being altered to ensure radiation measurement without saturation of the fluorescence detecting mechanism. To read the dose of radiation, the stimulable phosphor is illuminated with pulsed exciting light having a short time duration and the emission of stimulated fluorescence is detected with a photodetector, amplified with a charge-sensitive preamplifier, waveform shaped with a pulse shaping amplifier and passed through an analog/digital converter to provide pulse height data, which is processed by a data collecting and processing circuit to determine the dose of radiation accumulated in the stimulable phosphor.

摘要： A semiconductor radiation detector is equipped with a semiconductor detection device such as silicon or germanium and is used in qualitative and quantitative analysis of X-rays or gamma-rays while the detection device is cooled with a refrigerator that makes use of the adiabatic expansion of air or nitrogen gas being released from an adiabatic expansion valve. In accordance with the present invention, the periphery of the gas outlet of the adiabatic expansion valve at the tip of the refrigerator is covered with a gas-permeable fibrous or screen-like material or with a laminate of two or more perforated plates. This construction ensures a passage of gas flow and yet reduces the air vibration that would otherwise occur when the gas is released from the adiabatic expansion valve. The detector of the present invention provides an energy resolution that is just comparable to the value attained when the detector is cooled directly with liquid nitrogen.
