Accuracy Analysis of Focusing Mechanism for an ICF Facility

Abstract:

The focusing Mechanism is an important component of Final Optic Assembly (FOA) in an ICF facility. In this paper, focusing mechanism structure and factors that influence its targeting accuracy were discussed. The impact of the lens pose on targeting when four cylindrical guides were distributed in 4×90°is studied. And it was compared with the situation when three cylindrical guides distributed in isosceles triangle were used. The geometric model was built to analyze the target error caused by the deformation of the front and rear flat. In the end, the deformation was calculated by ANSYS. The result shows that the deviation change is minimized when the diameters of the support rods and guides take specific value.
