In order to deliver VUV (vacuum ultraviolet) photons under atmospheric pressure conditions, a differential pumping system has been built on the DISCO beamline at the SOLEIL synchrotron radiation facility. The system is made of four stages and is 840 mm long. The conductance-limiting body has been designed to allow practicable optical alignment. VUV transmission of the system was tested under air, nitrogen, argon and neon, and photons could be delivered down to 60 nm (20 eV).
为了在大气压条件下传输真空紫外(VUV)光子，在 SOLEIL 同步辐射设施的 DISCO 光束线上建立了一个差分抽气系统。该系统由四个阶段组成，长 840 毫米。设计了导纳限制体以允许实际的光学对准。该系统在空气、氮气、氩气和氖气下进行了 VUV 传输测试，并且可以传输到 60nm（20eV）以下的光子。
