Problems solved by technology

At present, the test fixtures of thin-film radiation dosimeters mostly adopt the spring clamp type. The defect of this method is: because the relative position of the two clamping surfaces of the fixture can be moved, the relative position of the fixture is not fixed in different measurements, resulting in multiple measurements of the test fixture. poor consistency

Embodiment Construction

[0022] Below by embodiment, the present invention will be further described.

[0023] like figure 1 As shown, the thin-film radiation dosimeter test fixture is made of duralumin material. The fixture is a cuboid, with four sides being rectangular, and the top and bottom are square; the four sides are respectively A, B, C, and D Surface, wherein the A surface is opposite to the C surface, and the B surface is opposite to the D surface; the top surface and the bottom surface are respectively the E and F surfaces; the size of the clamp matches the sample groove of the spectrophotometer;

[0024] Take the plane S parallel to the E and F planes in the fixture, the S plane is located at 1 / 2~1 / 3 of the height of the fixture, and the S plane intersects with the A, B, C, and D planes at a, b, and c respectively , d line; take the center of the S plane as the origin O to establish a space Cartesian coordinate system, the x axis of the coordinate system is perpendicular to the A plane, ...

Abstract

The invention relates to a film radiation dosage testing clamp, and belongs to the field of radiation test. The clamp is a cuboid; four sides of the clamp are rectangular; the top and bottom of the clamp are square; a counter bore G and a counter bore H coaxial to each other, a film clamping slit and a clamping groove are formed in the clamp; and a film radiation dosage meter is placed into the film clamping slit by the clamping groove during test. By utilizing the film radiation dosage testing clamp, faults caused by movement of relative oppositions of the film during different tests of the clamp are overcome, the clamping force of the film radiation dosage meter in the clamp is eliminated, and the film radiation dosage meter is in a natural extension state, so that the improvement on the testing accuracy is facilitated.

Description

technical field [0001] The invention relates to a film radiation dose testing jig, which belongs to the field of radiation testing. Background technique [0002] Thin-film radiation dosimeters can be used to measure radiation doses such as particles, gamma, electron beams, and X-rays, and are widely used in the field of radiation. In the field of spacecraft design, since the dose equivalence principle is used in the ground assessment of the ionization total dose effect of electronic devices and materials in the space radiation environment, the accuracy of the dose test affects the accuracy of the space ionization total dose effect ground assessment assessment. [0003] Thin-film radiation dosimeters are usually square thin-film sheets with a width of 1 cm and a thickness of tens of microns. According to the one-to-one relationship between the dose received by the thin-film radiation dosimeter in the irradiation field and the change of the absorbance of the thin-film radiati...
