Embodiment
For realize that sniffer responds smooth in the energy range of broad, the present invention is from ray and matter interaction principle, sniffer material, structure and physical dimension etc. are designed, developed the X ray energy and in the 40keV-800keV interval, responded smooth pulsed X-ray sniffer.
Be illustrated in figure 1 as the structural representation of a kind of twin scintillator offset-type of the present invention pulsed X-ray sniffer, it comprises the metal shell 5 of hollow, be arranged on the entrance window 6 and the exit window 7 at metal shell 5 two ends, exploring block and photodetector 8, exploring block is arranged on metal shell 5, entrance window 6 and exit window enclose in 7 one-tenth the cavity 10, photodetector is communicated with cavity by the hole that is provided with on the metal shell 5 and is fixed on the metal shell 5 by electric explorer shell 9, exploring block comprises inorganic thin film scintillator 2 and organic film scintillator 3, inorganic thin film scintillator 2 next-door neighbour's entrance windows 6 are provided with, organic film scintillator 3 next-door neighbour's exit windows 7 are provided with, and inorganic thin film scintillator 2 is put in opposite directions with organic film scintillator 3.Photodetector 8 can be photomultiplier, photoelectric tube and semi-conductor type photodetector.
Inorganic thin film scintillator 2 adopts is thickness between 0.1 to 0.5mm doping zinc oxide crystal, comprises ZnO:In and ZnO:Ga, and the inorganic thin film scintillator of other fast-response also can be used for this sniffer design; The organic film scintillator that adopted 3 is plastic scintillant, thickness between 0.05 to 0.5mm.
In order to improve the smooth scope of energy response: at entrance window 6 and 2 of inorganic thin film scintillators absorbing sheet 1 is arranged, be provided with backward scattering sheet 4 at exit window 7 and 3 of organic film scintillators.Absorbing sheet 1 can be metallic film materials such as iron, copper, nickel, zinc, silver, and thickness is between 10 to 200 μ m.Backward scattering sheet 4 is the silverskin of thickness between 50 to 200 μ m.
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 2 is the response curve of the organic plastics film scintillator of different-thickness to X ray between the energy 30keV to 800keV, the plots changes of different-thickness (0.1mm, 1.2mm, 0.3mm, 0.5mm, 0.8mm, 1.0mm) film is difference slightly, thicker organic scintillator increases and increases along with the X ray energy the response of X ray, and thin organic scintillator responds when energy is higher slightly and descends.As shown in Figure 3, inorganic scintillator ZnO:In film is to just opposite with the organic scintillator variation tendency in the energy of X ray is between this energy range.Two kinds of film scintillators are opposite to the energy response variation tendency of X ray, and inorganic scintillator is stronger to the low energy X ray response, and organic scintillator is stronger to the high energy partial response, exists complementary preferably.
For ease of the collection of light, take inorganic scintillator preceding, organic scintillator after in-line configuration, it is luminous that photodetector is collected scintillator by the side.Smooth for sniffer is responded in the energy range of broad simultaneously, certain material also need be set on beam channel, influence ray in scintillator self-energy deposition process by changing radiation environment, and then the governing response curve.Decay material in the scintillator front side can suitably reduce the response of low energy part, and response compensates to scintillator can to produce backscattered electron at the material of scintillator rear side setting.Explorer response is from organic film scintillator and inorganic thin film scintillator two parts, and the size of contribution is a proportionate relationship separately, and being what specifically needs to measure by experiment to determine, reduces film size and can reduce that it is luminous, and then reduce its contribution.Because the film scintillator is relevant with film thickness and residing environment to X ray response curve shape, and almost irrelevant with film scintillator area, so can regulate the relative luminous intensity of two kinds of film scintillators by adjusting flicker film relative area.The pulsed X-ray panel detector structure synoptic diagram of organic scintillator and inorganic thin film scintillator combination is as shown in Figure 1: the radiation detection parts are in the cavity that cylinder type metal shell 5 and entrance window 6 and exit window 7 surround; Wherein: inorganic thin film scintillator 2 is in the sniffer front end near entrance window 6 rear sides, is provided with absorbing sheet 1 between the two; Organic film scintillator 3 is in the sniffer rear end and is positioned at exit window 7 front sides, and backward scattering sheet 4 is arranged between the two; Metal shell 5 sides are connected with photodetector shell 9, and its internal fixation has photodetector 8.
The course of work of this sniffer measured X ray is: X ray enters sniffer inside through sniffer entrance window 6, with the matter interaction on the radiation channel, electronics that effect produces and inorganic thin film scintillator 2 and 3 effects of organic film scintillator make it luminous, the luminous photoelectric device 8 by the side of scintillator is collected and is converted electric signal output to, realizes the X ray detection.This sniffer needs collimation and shielding at work in addition.
This sniffer material and size combinations are not unique, as embodiment, the inorganic scintillator of 0.3mmZnO:In doping zinc oxide crystal material and 0.15mmST401 organic scintillator have been chosen as the radiation detection material, sniffer entrance window and exit window are 0.2mm aluminium, spacing is 10cm, what the absorbing sheet material adopted is 100 μ m iron films, and the backward scattering sheet material is the silver of 0.1mm, and photodetector is low noise photomultiplier.The sniffer response curve that obtains under this parameter as shown in Figure 4, response curve fluctuation is about 5% between 40keV to 800keV.Compare the relative luminous intensity of inorganic thin film scintillator and organic film scintillator by experiment, choose both diameters and be respectively 2.54mm and 2.12mm.
Inventive principle: typical hard X ray source energy covers tens to hundreds of keV, according to thinner thickness inorganic scintillator and organic scintillator are discovered in the X ray sensitivity response of this energy area, two kinds of thin scintillators have good complementarity to X-ray energy spectrum response curve shape, can obtain the smooth pulsed X-ray sniffer of energy response by organic scintillator and the combination of inorganic thin film scintillator.
