Abstract
Photomultiplier tubes are bonded using silicone gel, which cures to a soft state. Small glass or plastic spheres are placed in the gel before it has cured so as to weaken it and make it easier to shear when the photomultiplier tubes are twisted or tipped. The resulting bond is mechanically and optically adequate but not so strong as to make it impossible to remove a photomultiplier tube which must be replaced.
