Description
Technical field
The utility model relates to the use of plastic scintillant and photoelectric processing module demonstrates secondary powered cosmic ray track
Device, more particularly to a kind of cosmic ray track demonstrator.
Background technology
Secondary cosmic rays is that primary cosmic ray produces with atmospheric interaction, every square of metre per second (m/s) on sea level
About 100 charged particles of clock are passed through.These particles naked eyes can not be seen, and very weak with the interaction of material.Intuitively
To the presence of popular demonstration cosmic ray, understanding of the people to cosmology, particle physics and earth environment etc. can be lifted.Mesh
Before, in research laboratory, it is already possible to measure the track of cosmic ray well.But the equipment in laboratory is answered
It is miscellaneous, and portability is poor.But still lack in places such as school, popularization exhibitions can portable, the effective secondary universe of demonstration penetrate
The track device of line.
The content of the invention
The purpose of this utility model is to overcome problems of the prior art to be drilled there is provided a kind of cosmic ray track
Show instrument.
A kind of cosmic ray track demonstrator of the present utility model, it includes Plastic scintillation volume array, photomultiplier battle array
Row and photomultiplier high-pressure chassis, the Plastic scintillation volume array are arranged among plastic scintillant array support plate；It is described
Photomultiplier tube array is arranged among photomultiplier transit tube support plate；The photomultiplier high-pressure chassis by signal conductor with
Light emitting diode matrix correspondence in PCB is connected；The photomultiplier high-pressure chassis, photomultiplier transit tube support plate and
Plastic scintillant array support plate is fixed by four connecting rods with bottom plate.
The Plastic scintillation volume array, photomultiplier tube array and photomultiplier high-pressure chassis are arranged on two dimensional surface
Cross-section location it is consistent.
The cross section of every block of scintillator of the Plastic scintillation volume array is square, and the length of side is 1-2.5 cm2, plastics sudden strain of a muscle
Bright volume array is the multi-dimension array of multiple scintillator arrangement forms.
The utility model has advantages below compared with prior art：
1st, the utility model is simple in construction, is easily installed carrying.
2nd, the presence of the utility model ocular demonstration cosmic ray and cosmic ray track function, are conducive to helping people straight
The impression of sight those can't see impalpable cosmic ray.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model circuit control principle schematic diagram.
In figure：1-connecting rod, 2-bottom plate, 3-Plastic scintillation volume array 4-photomultiplier tube array, 5-photomultiplier transit

Embodiment
Such as a kind of Fig. 1 cosmic ray track demonstrator, it includes Plastic scintillation volume array 3, the and of photomultiplier tube array 4
Photomultiplier high-pressure chassis 5, Plastic scintillation volume array 3 is arranged among plastic scintillant array support plate 10；Photomultiplier transit
Pipe array 4 is arranged among photomultiplier transit tube support plate 9；Photomultiplier high-pressure chassis 5 passes through signal conductor 6 and PCB circuits
The correspondence of light emitting diode matrix 7 on plate 8 is connected；Photomultiplier high-pressure chassis 5, photomultiplier transit tube support plate 9 and plastics dodge
Bright volume array supporting plate 10 is fixed by four connecting rods 1 and bottom plate 2.The Plastic scintillation volume array 3, photomultiplier tube array 4
It is consistent with the cross-section location that photomultiplier high-pressure chassis 5 is arranged on two dimensional surface.Every piece of sudden strain of a muscle of Plastic scintillation volume array 3
The cross section of bright body is square, and the length of side is 1-2.5 cm2, Plastic scintillation volume array 3 is many of multiple scintillator arrangement forms
Tie up array.
Photomultiplier high-pressure chassis 5 is the base of the Cockcroft-Walton types driven by low-voltage dc power supply.From
The analog signal exported on base is wired in PCB.The one side of PCB is process circuit, another
Face is LED array.
The analog signal of the photomultiplier output of photomultiplier tube array 4 as shown in Figure 2, is converted by a discriminator
For data signal, the data signal of discriminator output is divided into two-way, is connected to one and door after a delay circuit all the way,
Another road is input to a logic programmable gate array（FPGA）In；Logic programmable gate array（FPGA）In with 200 M frequency
Rate scans each input, when any one input detects the rising edge of data signal, then with this time
For starting point, 500 ns window is opened；In this 500 ns window, if also detected that effectively in other inputs
Data signal, and the data signal detected be not less than three in the case of, logic programmable gate array（FPGA）Output one
Individual data signal；Logic programmable gate array（FPGA）The data signal of output, be separately input to each among door, logic
Programmable gate array（FPGA）Output signal and delay circuit in signal meet when being true, export a logic high with door
With for lighting corresponding LED.The operation of the equipment is very simple, it is only necessary in the case of switching on power, when band electric universe
When ray passes through detector array, light emitting diode corresponding with the scintillator cells hit（LED）It is lit, it can be seen that quilt
The track that the LED lighted is formed, is exactly the demonstration for intuitively completing cosmic ray track.
It is above the utility model preferably embodiment, the utility model those skilled in the art can also be to upper
State embodiment to be changed and changed, therefore, the utility model is not limited to above-mentioned embodiment, every ability
Any conspicuously improved, replacement or modification that field technique personnel are made on the basis of the utility model belong to this practicality
New protection domain.
