A novel interconnection assembly method was developed for the electron gun of airborne CRTs, which makes it possible for the connectors to be connected and disconnected repeatedly (as opposed to soldering as in the conventional method) to provide access to the tube and its interconnecting cable harness. Environmental tests were conducted on one series of CRTs, which included electrical and environmental conditions which would be experienced in a worst-case aircraft cabin environment, including the altitude, humidity, thermal shock, vibration, and mechanical shock.
