1. An X-ray apparatus as part of a particle beam cancer therapy system, said particle beam cancer therapy system irradiating a tumor of a patient with a charged particle beam during use, said apparatus comprising: an X-ray generation source located within forty millimeters of the charged particle beam, wherein said X-ray source maintains a single static position: (1) during use of said X-ray source and (2) during tumor treatment with the charged particle beam; an electron generating cathode; a control electrode; a plurality of accelerating electrodes; a magnetic lens; and a quadrupole magnet, all of said control electrode, said accelerating electrodes, said magnetic lens, and said quadrupole magnet located between said cathode and an X-ray generating anode in said X-ray generation source, said control electrode, said accelerating electrodes, said magnetic lens, and said quadrupole magnet combining to form a substantially parallel electron beam with an electron beam cross-sectional area, wherein a cross-sectional area of said cathode is greater than about eight times that of the electron beam cross-sectional area, wherein X-rays emitted from said X-ray source run substantially in parallel with the charged particle beam, and wherein said substantially parallel electron beam comprises an oblong cross-sectional shape, wherein geometry of said X-ray generation source yields an X-ray beam comprising a nearly circular cross sectional shape when struck by the electron beam having said oblong cross-sectional shape, the X-ray beam running substantially in parallel with the charged particle beam.
