The photoabsorption spectroscopic studies (PASS) beamline (PASS-BL07), installed at a bending magnet 450 MeV, 100 mA Indus-1 synchrotron source (India), is capable of performing photoabsorption studies in the vacuum ultraviolet to soft x-ray range of thin films and solid samples. The beamline covers an energy range of 55 eV-840 eV by an in-house developed SX-700 type plane grating monochromator. This energy range will cover the absorption spectra of low Z-elements like C, N, and O as well as the L and M threshold of 3d elements such as Ti, V, S, etc. The beamline will be significantly used for studying organic semiconductors, graphene, etc. In this article, the design details of the beamline and some of the recent scientific results have been presented.
安装在印度Indus-1同步加速器源（450 MeV，100 mA弯曲磁铁）上的光吸收光谱研究（PASS）光束线（PASS-BL07），能够对薄膜和固体样品在真空紫外到软X射线范围内进行光吸收研究。该光束线通过内部开发的SX - 700型平面光栅单色仪覆盖55 eV - 840 eV的能量范围。这个能量范围将涵盖低Z元素（如C、N和O）的吸收光谱以及3d元素（如Ti、V、S等）的L和M阈值。该光束线将大量用于研究有机半导体、石墨烯等。在本文中，介绍了光束线的设计细节以及一些近期的科学成果。
