Abstract

The embodiment of the invention provides an electron beam detecting system comprising an electron collecting device, a sampling box, a communication box, and a controller. The electron collecting device, together with an electron beam accelerator, is arranged in a shielding room and is used for detecting the intensity of an electron beam radiated by the electron beam accelerator to obtain a first signal. The sampling box that is arranged in the shielding room and is connected with the electron collecting device is used for receiving the first signal and converting the first signal into a second signal that is in an optical signal manner and can reflect the irradiation uniformity of the electron beam. The communication box that is arranged outside the shielding room and is connected with the sampling box by a fiber is used for receiving the second signal by the fiber and converting the second signal into a third signal in an electric signal manner. The controller that is arranged outside the shielding room and is connected with the communication box is used for receiving the third signal. Therefore, the detection control of the electron beam is realized.

Description

technical field [0001] The invention relates to the technical field of radiation processing, in particular to an electron beam detection system. Background technique [0002] Irradiation technology is the use of the interaction between rays and substances, ionization and excitation of activated atoms and activated molecules, so that a series of physical, chemical, and biochemical changes occur between them and substances, resulting in the degradation, polymerization, crosslinking, and degradation of substances. and undergo modification. Due to the superiority of its processing, irradiation technology has achieved rapid development, and the processing objects are becoming more and more extensive. The processed product itself has a certain volume, the distance from the source is not equal, and the absorbed dose in the same batch of products is uneven. When the absorbed dose of the product is lower than the effective dose, the required radiation effect cannot be produced, and...
