Abstract

A cathode assembly for a vacuum tube includes a wire filament, a straight bular anode parallel to and surrounding the wire filament, and insulating spacers for rigidly fastening the filament with respect to the anode, and with one side of the anode indented or flattened such that only one portion of the anode is heated to emitting temperatures by the filament.

Rigid indented cylindrical cathode for x-ray tube

Patent Hudgens, C R

A cathode assembly for a vacuum tube includes a wire filament, a straight tubular anode parallel to and surrounding the wire filament, insulating spacers for rigidly fastening the filament with respect to the anode, and with one side of the anode indented or flattened such that only one portion of the anode is heated to emitting temperatures by the filament.
Orthogonally interdigitated shielded serpentine travelling wave cathode ray tube deflection structure

Patent Hagen, Edward C [Las Vegas, NV]; Hudson, Charles L [Santa Barbara, CA]

A new deflection structure (12) which deflects a beam of charged particles, uch as an electron beam (15), includes a serpentine set (20) for transmitting a deflection field, and a shielding frame (25) for housing the serpentine set (20). The serpentine set (20) includes a vertical serpentine deflection element (22) and a horizontal serpentine deflection element (24). These deflection elements (22, 24) are identical, and are interdigitatedly and orthogonally disposed relative to each other, for forming a central transmission passage (75), through which the electron beam (15) passes, and is deflected by the deflection field, so as to minimize driftmore »« less

Shielded helix traveling wave cathode ray tube deflection structure

Patent Norris, Neil J [Santa Barbara, CA]; Hudson, Charles L [Santa Barbara, CA]

Various embodiments of a helical coil deflection structure of a CRT are described and illustrated which provide shielding between adjacent turns of the coil on either three or four sides of each turn in the coil. Threaded members formed with either male or female threads and having the same pitch as the deflection coil are utilized for shielding the deflection coil with each turn of the helical coil placed between adjacent threads which act to shield each coil turn from adjacent turns and to confine the field generated by the coil to prevent or inhibit cross-coupling between adjacent turns ofmore »« less

X-ray tube with magnetic electron steering

Patent Reed, Kim W [Albuquerque, NM]; Turman, Bobby N [Albuquerque, NM]; Kaye, Ronald J [Albuquerque, NM]; ...

An X-ray tube uses a magnetic field to steer electrons. The magnetic field urges electrons toward the anode, increasing the proportion of electrons emitted from the cathode that reach desired portions of the anode and consequently contribute to X-ray production. The magnetic field also urges electrons reflected from the anode back to the anode, further increasing the efficiency of the tube.
