Gas monitoring running at the completed HotBENT experiment

After the revision of one of the valves of the gas circulation system at the HotBENT experiment, on Sept. 16th 2021 the gas monitoring of all sampling ports within the drift was launched. This will allow observation of possible changes in the gas composition even during the early stages of the experiment.
