Title: Radiation detector
Inventor: MATSUOKA TAKESHI
IPC: G01T1/17
Filed: 1989-06-26
Abstract: PURPOSE:To detect radiation of high intensity by comparing the output of each of charge amplifiers with a reference voltage level and discharging the charges stored in the feedback capacities of all of the charge amplifiers at the point of time when the outputs of the charge amplifiers reach the reference voltage level. CONSTITUTION:When radiation is continuously incident to each of radiation detectors S, the feedback capacity CF of each of charge amplifiers 1 is charged with the charge from each of the radiation detectors S and the output voltage of each amplifier 1 rises. The output voltage of the charge amplifier 1 is always compared with reference voltage Vref by a comparator and, at the point of time when the output voltage exceeds the reference voltage Vref, a reset pulse signal is supplied to a switch SW1. The switch SW1 is instantaneously turned ON by said pulse signal and the charge of the feedback capacity CF is discharged. Herein, the reference voltage Vref set to the comparator 3 may be equal to or less than the saturated voltage of the charge amplifier 1 and, as said set value becomes lower, energy resolving capacity is enhanced.

Abstract: PURPOSE:To give any frequency characteristics to a signal converter composed of a couple of coils series-connected differing in polarity to a delay line medium of an amorphous magnetic substance, by providing the converter to input and output parts of the delay line medium. CONSTITUTION:To input and output parts of delay medium 7 of an amorphous magnetic substance, signal converter 8 is provided which consists of coils 9 and 10 wound around bobbin 11. Coils 9 and 10 are opposite in coil winding direction and connected in series differing in polarity. When an electric signal is inputted to this signal converter 8, magnetic strain corresponding to the winding direction of each coil and its magnetization is generated in the delay medium near the coil and the relation between the strain value and direction is shown by S, so that converter 8 will provide conversion into a delay signal taking as a center frequency a signal equivalent to the wavelength of S. Since the frequency of this signal is determined by the width of the coil in the length direction, coils of various widths are combined and the number of times of windings is selected, so that any frequency characteristics can be given to the converter.
