Abstract
The utility model discloses a plastic scintillator detector for radiation detection, and relates to the field of measuring instruments. The plastic scintillator detector comprises a base and a scintillator disposed on the base. Photomultipliers are disposed on an upper end of the scintillator and on the base. An inner wall of the scintillator is disposed with lead or copper. The plastic scintillator detector overcomes problems of sensitivity, resolution ratio, etc. in the prior art, and reduces cosmic radiation background of a main detector or gamma-ray Compton scattering background.
Description
Technical field
The utility model relates to the surveying instrument field, relates to the plastic scintillator detector that is used for radiation detection of a kind of detectable gamma-rays or μ neutron in particular.
Background technology
The radiation detector that the plastic scintillator detector that is used for radiation detection on the present home market mainly is made up of the collecting part and the electrooptical device of scintillator, light.When particle got into scintillator, the atom of scintillator or molecule were excited and are produced fluorescence.Utilize the collecting part of light such as photoconduction and reflecting body to make fluorescence as often as possible be mapped on the photosensitive layer of electrooptical device and get photoelectron.These photoelectrons form electric pulse by the output stage collection after can directly or passing through and doubling.A lot of materials can be after particle incident and stimulated luminescence, so the kind of scintillator is a lot, can be solid, liquid or gas.But like product sensitivity and resolution are all lower on the market.
The utility model content
Be deficiencies such as the sensitivity that overcomes like product in the prior art and resolution; The utility model provides a kind of novel plastic scintillator detector that is used for radiation detection; It comprises base and is arranged at the scintillator on the base; Be respectively arranged with photomultiplier on said scintillator upper end and the base, said scintillator inwall is provided with lead or copper.
Wherein, the integrated setting of said base and scintillator.
Compared with prior art; The described beneficial effect that is used for the plastic scintillator detector of radiation detection of the utility model is; Detectable gamma-rays or μ meson, particles such as fast neutron are the main support equipments of the low background gamma ray spectrometer measurement mechanism of anticoincidence as the anticoincidence shielded probe.Photomultiplier through some meets or the anticoincidence signal with special-purpose electronics equipment generation accordingly; The main detector of the low background gamma ray spectrometer measurement mechanism of control anticoincidence writes down or does not write down the signal that is detected, and reaches the cosmic rays background of reduction main detector or the purpose of gamma-rays Compton scattering background.
Description of drawings
Fig. 1 is the described structural representation that is used for the plastic scintillator detector of radiation detection of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the structural representation of the utility model.As shown in Figure 1, the utility model comprises base 1 and is arranged at the scintillator 2 on the base that be respectively arranged with photomultiplier 3 on said scintillator 2 upper ends and the base 1, said scintillator 2 inwalls are provided with lead or copper.Said base 1 and scintillator 2 integrated settings.
The detectable gamma-rays of plastic scintillator detector or the μ meson that are used for radiation detection; Particles such as fast neutron; As the anticoincidence shielded probe is the main support equipment of the low background gamma ray spectrometer measurement mechanism of anticoincidence; The main detector (being generally high purity germanium detector) of the low background gamma ray spectrometer measurement mechanism of anticoincidence is positioned at the central interior of the plastic scintillator detector that is used for radiation detection during use, also can increase certain thickness lead between main detector and the plastic scintillator detector that is used for radiation detection, and materials such as copper shield; When detector is explored gamma-rays or μ meson; Behind the particles such as fast neutron, meet or the anticoincidence signal the low background gamma ray spectrometer of control anticoincidence accordingly through the photomultiplier (photoconduction can be set up in the front portion) of some and special-purpose electronics equipment generation
The main detector of measurement mechanism writes down or does not write down the signal that is detected, and reaches the cosmic rays background of reduction main detector or the purpose of gamma-rays Compton scattering background.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineering technical personnel in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
