Kinematics and Workspace Analysis of Target Alignment Sensor for ICF

Inertial confinement fusion(ICF) is one of the main ways to realize controllable thermonuclear fusion energy. It has high precision requirements for the aiming and positioning of experimental targets. The target alignment sensor for ICF is used to achieve beam-target coupling, and its adjustment accuracy will directly affect the accuracy of the target experiment. First, this article introduces the function and structure of the ICF target alignment sensor(TAS). Then, the inverse kinematics solution of the 6-PTRT parallel manipulator with parallel posture adjustment mechanism is calculated, and the constraints of the inverse solution are given. Finally, the three-dimensional search method is used to search the working space of the parallel robot in a given attitude and convert it into the working space at the end of the target alignment sensor.
