Second spare bellows appears to hold pressure. RF has requested that we wait ~0.5h to turn the RF back on, to avoid the need for another survey if another leak arises in that time.

Leak has been found downstairs in the 1L12-5 waveguide. It initially appeared to be an aging gasket failing, but is now almost certain to be a cracked bellows. A spare has been secured and the swap will begin shortly.
