[0001] The utility model relates to the technical field of radiation gradient detection, in particular to a ladder-shaped bracket for an electron accelerator. Background Art

[0002] Electron radiation accelerators have been widely used in the medical and production fields. The radiation generated by their work needs to be measured in gradients to facilitate safety protection. There are many methods for measuring absorbed doses. The most common method is to use color-developed thin-film dose sheets. For example, the FWT-60-00 thin-film color-developed dose sheet measures the absorbed dose during irradiation processing with a 1 MeV low-energy electron beam.

[0003] When using a dose sheet, the position of the dose sheet needs to be maintained for a long time. Currently, there is no dedicated bracket for use, which makes the electron accelerator height dose distribution measurement operation relatively cumbersome. Therefore, the utility model provides an electron accelerator ladder bracket. Utility Model Content
