ISS received the first light on 10.07.2025. After that, the endstation has been reconnected and aligned. During the shutdown period, the ScientaOmicron R4000 HiPP-2 analyser has undergone maintenance and upgrade. It features now a new detector (new MCP and 70 Hz camera) and ethernet communication. Other improvements regarding the solid-gas interface endstation:
1) New design of the measurement cell, with the possibility to replace/customize it.
2) New gas dosing system based on a modular concept (mass flow controllers and fast -piezoelectric- valves), fully controlled by Labview. The new system is versatile for both steady state- and modulation excitation-experiments.
3) Integrated bakeout. Flow tubes connected to the experimental cell are equipped with heating elements to bake them (including the cell) in between beamtimes. This will allow limiting cross-contaminations.
4) New control panels. A new Labview interface has been programmed. This allows accessing all controls/instruments within the same main panel and sub-tabs.
