Abstract
The utility model relates to a thermoluminescence measuring device. The thermoluminescence measuring device comprises a heater and a measuring plate, wherein the measuring plate is provided on the heater. The thermoluminescence measuring device further comprises a baffle plate. A measuring hole is provided on the center of the baffle plate. The baffle plate is arranged above the heater. The measuring hole is aligned with a light emission direction of the measuring plate. Compared with the prior art, the thermoluminescence measuring device has the advantages that the thermoluminescence measuring device can carry out large dose measuring, etc.
Description
Technical field
The utility model relates to a kind of measurement of thermoluminescence device, especially relates to a kind of measurement of thermoluminescence device.
Background technology
The measurement of thermoluminescence appearance has corresponding read range as the reader of thermoluminescence element.It overlaps light-receiving by a heater element 1 and one and amplification system is formed, and is as shown in Figure 1.But because measuring instrument is in the factor of aspects such as design, manufacturing; Its measurement range is basically between 1mrad～100rad; When readout surpasses 100rad, just exceeded the detection upper limit of measuring instrument, just can't carry out correct measurement for this measuring instrument under the heavy dose of situation of needs measurement.
The utility model content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of measurement of thermoluminescence device to be provided.
The purpose of the utility model can realize through following technical scheme:
A kind of measurement of thermoluminescence device comprises well heater and measuring disk, and this measuring disk is located on the well heater; It is characterized in that, also comprise baffle plate, these baffle plate central authorities are provided with measured hole; Described baffle plate is located at the well heater top, and described measured hole is aimed at the light emission direction of measuring disk.
The area of described measured hole is 1/32 of a heater area.
Compared with prior art, the utlity model has following advantage:
1) can carry out heavy dose of measurement;
2) through repeatedly experimental verification, draw the measurement pore size and be directly proportional with measuring readout, and linear good;
3) light that discharges is original 1/32nd through amount after the heating, has so correspondingly improved 32 times measuring the upper limit.
Description of drawings
Fig. 1 is existing measurement of thermoluminescence apparatus structure synoptic diagram;
Fig. 2 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 2, a kind of measurement of thermoluminescence device comprises well heater 5 and measuring disk; This measuring disk is located on the well heater; It is characterized in that, also comprise baffle plate 4, these baffle plate 4 central authorities are provided with measured hole 3; Described baffle plate 4 is located at the well heater top, and described measured hole 3 is aimed at the light emission direction 2 of measuring disk.
Described heater area is 5mmx5mm=25mm
2, the aperture of the measured hole 3 on the baffle plate is 1mm, measured hole 3 is 0.785mm for the area of a circle of 1mm so
2, like this with measuring disk area 25mm
2Compare its area and be about 1/32nd of measuring disk, the light that discharges after the heating is original 1/32nd through amount, has so correspondingly improved 32 times measuring the upper limit.
Claims (2)
