ABSTRACT:
An electron beam tube device has a magnetic frame with the top part being pivotable so as to pivot from a closed position in which the top part, including an electromagnetic coil covers the electron beam tube to an open position in which the electron beam tube is uncovered. This allows electron beam tubes with either large parts or integral parts such as output feeders to be removed from the magnetic frame without complete removal of the top plate.
