摘要：

The optical design of a soft x-ray beamline on the bending magnet of Indus-2 synchrotron source is presented. A Varied Line Spacing Plane Grating Monochromator (VLS-PGM) was adopted with Hettrick type optics. The VLS-PGM consists of a spherical mirror and three interchangeable gratings of line densities 1200 l/mm, 400 l/mm and 150 l/mm to efficiently cover the energy region 50-1500 eV. The VLS groove parameters were obtained by minimizing defocus aberration, coma and spherical aberration. The overall performance of the beamline was estimated by detailed raytracing calculations. The beamline design, results of the raytracing calculations and the expected performances are presented.
