摘要： An X-ray tube can include: a cathode including an electron emitter that emits an electron beam; an anode configured to receive the electron beam; a first magnetic quadrupole between the cathode and the anode and having a first yoke with four first pole projections extending from the first yoke 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 between the first magnetic quadrupole and the anode and having a second yoke with four 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 steering coil collocated with a quadrupole on a pole projection.
