Measuring equipment of electron accelerator output beam parameter

Abstract

The invention provides measuring equipment of an electron accelerator output beam parameter. The measuring equipment comprises: an electron absorption board (8) and a plurality of electron absorption rods (7), wherein the each electron absorption rod is insulated with other components. The electron absorption rods possess a same rectangular section which is parallel to the electron absorption board. A length direction is parallel to the width direction of an accelerator scanning output window (11). Side surfaces with the same width of the electron absorption rods are vertical to an electron ray direction which is located in a position of the electron absorption rods. The electron absorption board and each electron absorption rod are connected to a current measurement device through leads respectively. Compared to the prior art, by using the measuring equipment of the invention, the electron beam energy measurement is integrated with the scanning uniformity measurement. Therefore, amounts of the accelerator output beam, a spectral distribution situation, the scanning uniformity can be simultaneously determined. The equipment and the apparatus needed by electron beam output parameter measurement can be simplified. In the prior art, the different apparatuses are needed by the electron beam energy measurement and the electron beam scanning uniformity measurement. By using the measuring equipment of the invention, the above problem can be solved.

Description

technical field [0001] The invention relates to a measuring device for the output beam parameters of an electron accelerator, which is a device for comprehensively measuring the output electron beam intensity, energy spectrum distribution and scanning uniformity of the electron accelerator, especially a parameter data acquisition device. Background technique [0002] The electron accelerator involved in the present invention is a device that accelerates electrons close to the speed of light, and then irradiates the object to be irradiated through the accelerator scanning output window (commonly known as titanium window). The output beam current of the titanium window, that is, the intensity, energy spectrum distribution and scanning uniformity of the electron acceleration beam directly affect the irradiation effect of the irradiated object, while the electron beam outside the output window of the accelerator scans, the electrons contained in it Except that the ray is a strai...

Problems solved by technology

"That is to reflect the energy of the electron beam by converting the electric signal converted by the charge accumulated on the absorbing plate, but one is that the detection parameter of the device is single, and the other is that the device is installed on the edge of the titanium window, which cannot truly reflect the radiation of the electron accelerator. electron beam energy
