    keyword=Leak in nitrogen line

    There is a gas leak on the nitrogen line, inside the methane swtichover controller.
    The leak is on the valve controlling the left methane bottle. I put the right bottle
    on line. The nitrogen supply ran out, shutting down the gas system. I am out of
    nitrogen bottles, so I put an argon bottle on line. I shut off the nitrogen line to
    the RICH detector freon purge.
