    摘要: An X-ray tube can include: a cathode including an electron emitter; an anode configured to receive the emitted electrons; a first magnetic quadrupole between the cathode and the anode and having a first quadrupole yoke with four first quadrupole pole projections extending from the first quadrupole yoke and oriented toward a central axis of the first quadrupole yoke and each of the four first quadrupole pole projections having a first quadrupole electromagnetic coil; a second magnetic quadrupole between the first magnetic quadruple and the anode and having a second quadrupole yoke with four second quadrupole pole projections extending from the second quadrupole yoke and oriented toward a central axis of the second quadrupole yoke and each of the four second quadrupole pole projections having a second quadrupole electromagnetic coil; and a magnetic dipole between the cathode and anode and having a dipole yoke with four dipole electromagnetic coils.
