Abstract:By the method of ion-beam shape correction, a small-sized ion beam formed a non–axisymmetric aspherical profile of the collector surface for an extreme ultraviolet radiation source TEUS-S100 with a numerical aperture of NA= 0.25, PV on the surface is 36.3 microns, the surface shape accuracy by standard deviation is 0.074 microns, which allowed to obtain a focusing spot with a width of 300 microns at half-height. To solve the problem, the technological ion source KLAN-53M was upgraded – the flat ion-optical sys… Show more
