Analysis And Research Of KTX Reversed Field Pinch Device Assembly Technology

Reversed field pinch (RFP) is one of the world’s three modern major magnetic confinement fusion research devices, which is one class of toroidal magnetic confinement fusion apparatuses other than Tokamak and Stellarator. Keda Torus eXperiment (KTX) is the first large Chinese RFP machine, under construction in University Of Science And Technology Of China (USTC), with advantages of both MST and RFX-mod. Recently, The KTX project has moved into its last stage of Constructions, assembly, essential phase to ensure the quality of the KTX, right after its successful R&D. This dissertation analytically studied the KTX assembly technology and measurement to make sure its accurate assembly process.The basic parameters, main physics goals and components of the machine are given in this article and the structures description of major machine components is provided in details. We provided the assembly process of apparatus through analytical study of key components assembly technology according to KTX’s structural properties, furthermore, we optimized and improved the install process in field assembly step.We come up with an assembly accuracy plan of KTX via relatively deep research on establishment of survey control network using precise engineering survey technology. Two different approaches of network establishment has been proposed in this paper, total station and laser tracker-based assembly control network respectively, to ensure the assembly accuracy of KTX. Comparing these two approaches, we ultimately decide to employ the more explicit and convenient way, three-dimensional coordinate control network, for network building. Moreover, uncertainty simulation analysis of two main approaches has been done in order to guarantee the quality of control network, accurate installation and measurement.
