Abstract

This paper introduces a new type of flexural pivot, which is a substitute for cross-stripe flexural pivot in the servo- reflector in ICF Laser Driver in China for higher stability and resolution. This paper presents force analysis model of the new flexural pivot. On the basis of force analysis, the torsional stiffness and rotational center drifting are calculated theoretically. In the meantime, FEM and a prototype test were carried out to verify the theoretical result. The integrated test shows that the new flexure pivot can provide sensitively adjusting with low center drifting. The resolution of the stepper-reflector system reaches 2 (mu) rad. And the repeatability of the reflectors with this new type flexural pivot is no more than 0.1 (mu) rad.
