On Nov. 21st-23rd I collected my first gas samples from the Full-Scale Emplacement (FE) Experiment in the Mt. Terri Rock Laboratory. As each sample required about 2 hours of gas circulation, I spent 3 days working in the tunnel. The absence of sunlight was compensated by local products from St. Ursanne.
The work related to our investigations in the AlpTransit Ceneri Base Tunnel has been accepted for publication! The un-edited version of the manuscript is already on-line.
