Abstract

A holder (50) for an arc tube-shroud assembly comprises: a planar disc (54) having a plurality of shroud-holding arms (56) peripherally spaced about the disc and extending in a first direction. At least two arc tube holding arms (60,60a) extend in an opposite direction (62) for positioning an arc tube laterally within a shroud; and at least one arc tube locking tab (64) extends in the opposite direction (60) for positioning the arc tube axially within the shroud. The planar disc (54) is provided with a plurality of venting apertures (82) sized to allow egress of pressurized gases but inhibit passage of axially-propelled arc tube shards in the event of a non-passive failure of an arc tube.
