摘要：An X-ray source with a cathode (2) formed as a cylindrical electrode having a hollow central anode tube (4) on its axis, with a grid (6) surrounding the anode (4) and interposed between the anode (4) and cathode (2). The central anode tube (4) is hollow and filled with a lasing medium. A high voltage is applied to the cathode (2) but the flow

of electrons to the anode (4) is blocked by the grid (6) which is held at ground potential. After a space charge is created at the grid (6) by electrons from the cathode (2), a very short high voltage pulse is applied to one end of the grid (6), yielding a relativistic wave of potential which propagates along the axial length of the grid. This wave of potential releases the electrons from the grid (6), which flow directly from the grid (6) to the anode (4). The impingement of the electrons on the tubular anode (4) produces X-rays from the interior surface of the anode tube (4). These X-rays pump the lasing medium along the length of the anode (4), causing a population inversion leading to the release of coherent X-ray in a wave synchronized with the propagating grid potential which exits the structure at the far end of the anode. The X-ray source may consist of identical unit coupled together in series to provide a high power X-ray beam, and may be configured in other cylindrical shapes depending on the output desired.
