CATHODE-RAY LAMP Russian patent published in 2008 - IPC H01J21/10 

FIELD: electronic equipment.

SUBSTANCE: cathode-ray lamp contains electronic-optical system, which consists of multi-ray cathode (1) with tape cathodes (2), cylindrical forming (3), accelerating (4) and electrically connected to multi-ray cathode (1) protective (5) electrodes, which are arranged with profiled windows that are coupled with tape cathodes (2), anode (9), and axial system of electrically insulated current leads (11, 12 and 14) accordingly heating, cathode (1) and accelerating electrode (4). Internal cylindrical surface of forming electrode (3), which is coaxially installed in respect to central tube (21) with bushing (16) of multi-ray cathode (1), equidistant from lateral surfaces along perimeters of end flanges (17 and 18) of bushing (16) of multi-ray cathode (1). Forming electrode (3) with its one end is fixed along the perimeter at axial current lead (13), which is installed in the system of current leads between current leads (12 and 14) of cathode (1) and accelerating electrode (4) and is electrically isolated from them, with possibility of its other end displacement and is electrically isolated from central tube (21) and bushing (16) with tape cathodes (2).

EFFECT: increase of oscillating power and electronic efficiency factor of appliance; increase of lamp working frequency; control of lamp with relatively low potential.
