Description
The ISIS INTER beamline is a high-flux neutron reflectometer capable of achieving high resolution and fast measurement speeds. A catalytic reaction study involving ionic liquids (ILs) has been proposed to take advantage of this capability. This area of research requires a challenging bench-top sample environment chamber that is compatible with pressurised flammable gases (up to 145 bar H₂, H₂/CO mixtures, or H₂ and alkenes) and can operate at controlled elevated temperatures (ambient to 200 °C). Such applications pose a significant fire hazard on the beamline, which was not originally designed for explosive gas atmospheres. The construction of this system therefore requires a high level of design safety to mitigate operational hazards. This presentation introduces the ongoing design work, including concepts, stress and thermal analyses, heating methods, control strategies, and protection measures. It also discusses interpretations of relevant codes and regulations, with the aim of sharing experience and knowledge with colleagues attending DENIM.
