Abstract

The invention discloses an electron curtain accelerator which comprises a positive electrode cylinder and a negative grating module located in the positive electrode cylinder. The electron curtain accelerator further comprises an insulation maintaining structure connected to the inner side of the positive electrode cylinder, and the negative grating module is maintained to the insulation maintaining structure. According to the electron curtain accelerator, a power supply part and a fixing structure of the negative grating module are separated, the insulation maintaining structure is independently arranged to serve as the fixing structure, use of expensive high-voltage insulation materials can be avoided, and the cost for fixing the negative grating module is reduced under the premise that the electrical indexes of the electron curtain accelerator are met.

Description

Technical field [0001] The invention relates to the field of irradiation equipment, in particular to an electron curtain accelerator. Background technique [0002] The cathode grid assembly of the electron curtain accelerator is at a negative high voltage under normal working conditions, and it is necessary to fix the cathode grid assembly in the center area of ​​the vacuum chamber through a high-voltage fixing structure and keep a proper distance from the surrounding grounded anode cylinder. [0003] In the prior art, most electron curtain accelerators directly fix the cathode grid assembly on the insulating voltage-resistant material, and the filament and the grid voltage supply are connected to the cathode grid assembly through the insulating voltage resistant material. There are mainly two types of high-voltage fixing structures in the prior art: one is a side wall fixed high-voltage fixed structure, and the other is a hoisting high-voltage fixed structure. [0004] figure 1 It ...
