The Large Hadron Collider (LHC) is the next accelerator being constructed at CERN. Over 40000 in-situ welds will be performed on the helium and vacuum systems in the LHC tunnel. Elastomer clamshell tools have been developed to permit high sensitivity leak testing of welded tubular connections using the so-called "hood" technique. The application, design and peformance of the clamshell tool will be described.
