Abstract

The invention discloses a remote control maintenance structure for a spallation neutron source target body plug-in piece. The remote control maintenance structure comprises the target body plug-in piece and a target seat arranged at the bottom of the target body plug-in piece, wherein a first cooling liquid pipeline is arranged inside the target body plug-in piece; a second cooling liquid pipelineis arranged inside the target seat; a transitional disk is also arranged between the target body plug-in piece and the target seat; the transitional disk is communicated with the first cooling liquidpipeline and the second cooling liquid pipeline. According to the remote control maintenance structure for the spallation neutron source target body plug-in piece, by improvement of a cooling system,a locating and assembling mode and a thermocouple assembly on the target body plug-in piece and the target seat, on the basis of no extra mounting of a counterweight block, removal of a cooling lineor removal of a thermocouple, sealed connection, electrical connection and high-precision localization between the target body plug-in piece and the target is realized.

Description

technical field [0001] The invention belongs to the technical field of spallation neutron sources, in particular to a remote control maintenance structure for a spallation neutron source target plug-in. Background technique [0002] The target insert is the core component of the spallation neutron source, and also the source of the neutron beam. The high-energy protons generated by the accelerator of the spallation neutron source bombard the target insert to generate neutrons. When the target system is in operation, the target insert will be bombarded by protons. The target material of China Spallation Neutron Source (CSNS) is high-density metal tungsten. Under the bombardment of high-energy protons, the material will produce atomic ionization If the damage is damaged to a certain extent, the target insert needs to be replaced. [0003] Replacing the target plug-in is a process of replacing the old target plug-in with a new target plug-in. The steps mainly include dismantli...
