X-ray tube having planar emitter and magnetic focusing and steering components |
| abstract |
An X-ray tube can include: a cathode planar emitter that emits an inhomogeneous electron beam; an anode to receive the electron beam; a first magnetic quadrupole having a first yoke with four evenly distributed first pole projections extending from the first yoke (404) and oriented toward a central axis of the first yoke and each of the four first pole projections having a first quadrupole electromagnetic coil; a second magnetic quadrupole having a second yoke (402) with four evenly distributed second pole projections extending from the second yoke and oriented toward a central axis of the second yoke and each of the four second pole projections having a second quadrupole electromagnetic coil; and at least one coil (on 450) of a first pair of opposing coils with alternating current offset from the power supply. Alternative soultions i.a. with AC offset current directly to quadrupole coils instead of the separate coil as well as details of the emitter are disclosed. |
