Abstract
A mount for an arc discharge lamp has a cathode thereon which is encircled by a disintegration shield. The shield has a narrow gap between its ends with a mercury containing metal capsule in the gap. The lower portion of the capsule is connected to the ends of the shield so that when an Rf current is induced in the shield, it preferentially flows through the lower portion of the capsule.
