Abstract:
A cathode ray tube, which has a getter assembly (18) for providing proper vacuum conditions within the tube. The getter assembly (18) comprises a resilient strip (19) having a first end portion (23) and a second end portion (25), and is detachably secured to a high voltage contact (15). A getter cup (21) is connected to the first end portion (23). The second end portion (25) is cooperatively engaged with one, preferably two protrusions (30) for limiting lateral movements of the resilient strip (19). The protrusions (30) are provided inside the envelope (5) of the tube. This arrangement reduces the risk of obtaining a layer of getter material at the wrong location within the tube.
