用于阻挡Z箍缩飞溅物的旋转开口圆盘系统
Rotating Open Disc System for Blocking Z-Pinch Debris
摘要
Abstract
In the later stage of the Z-pinch plasma implosion,the debris produced will contaminate the optical components of the diagnostic equipment.In this paper,the debris blocking system using a rotating open disc is designed,which can quickly block the optical channel after the X-ray incident onto the detector,thereby achieving the protection of the diagnostic system.The blocking principle of the rotating open disc is analyzed,and the shape,size,and rotational speed of the disc are designed.It is calculated that the range of debris velocity that the disc can block is 112.4-104 m·s-1,and the allowable time jitter is 12.5 μs.In addition,the stress,deformation,and mode of the rotating open disc are analyzed by finite element simulation.Based on the analysis results,the open disc is optimized to reduce the maximum stress value by 45％.Finally,a synchronous triggering scheme is given to ensure that the X-ray emission is triggered synchronously while the optical channel is open.关键词
