Liquid degrader device

Abstract

This invention relates to a liquid energy reduction device that uses water as the energy reduction medium and achieves high-precision proton energy control by adjusting the water layer thickness, significantly reducing the defects of traditional materials. Furthermore, the liquid energy reduction device features low cost, ease of maintenance, and high safety, providing a better solution for radiation testing of space electronic components.

Claims

1. A liquid energy reduction device, comprising: a variable container, a first fixing member, a second fixing member, a plurality of linear guide rods, a telescopic unit, an inlet pipe, an outlet pipe, and a temperature-controlled circulator, wherein the first fixing member and the second fixing member are connected and fixed by the plurality of linear guide rods, so that the variable container can be fixedly clamped between them, and the wall of the variable container has a telescopic structure to adjust its wall length; the telescopic unit is disposed below the first fixing member and has a telescopic rod, one end of which is connected to the second fixing member, and by moving the telescopic rod, the second fixing member is displaced relative to the first fixing member, thereby causing the variable container to be stretched through the telescopic structure to increase its thickness or compressed to decrease its thickness, thereby changing the thickness of the liquid through which the proton beam penetrates the variable container, thereby increasing or decreasing the energy of the proton beam; the variable container is provided with an inlet and an outlet on one side facing the first fixing member; The first fixing member has an opening at both the inlet and the outlet, thereby allowing the inlet and the outlet to be connected to one end of the inlet pipe and the outlet pipe; the temperature-controlled circulation machine is located below the variable container, and the inlet pipe and the outlet pipe are connected to the temperature-controlled circulation machine at the other end connected to the inlet and the outlet.

2. The liquid de-energizing device as described in claim 1, wherein the inlet is located below the outlet.

3. The liquid energy reduction device as claimed in claim 1, wherein a first collimation unit and a second collimation unit are removably disposed on the first fixing member and the second fixing member, respectively.

4. The liquid energy reduction device as described in claim 3, wherein both the first collimation unit and the second collimation unit are provided with a collimation hole.

5. The liquid de-energizing device as described in claim 4, wherein the collimation holes on the first collimation unit and the second collimation unit are arranged in parallel relative to each other.

6. The liquid de-energizing device as claimed in claim 1, wherein the variable container can add a liquid to its interior.

7. The liquid de-energizing device as described in claim 6, wherein the liquid is water.

8. The liquid de-energizing device as claimed in claim 1, wherein the variable container is cylindrical.

9. The liquid de-energizing device as claimed in claim 1, wherein the variable container is made of polyethylene, high-density polyethylene or silicone.
