摘要： An X-ray source is proposed having a rotating piston tube (2) which is mounted such that it can rotate, in which a stationary guide body (12), which at least partially surrounds the tube, is provided for cooling the anode plate (4). The guide body (12) is designed such that a liquid coolant, which is supplied to the tube (2) from a reservoir (15) concentrically with respect to the anode-bearing shaft (17), is initially positively guided along the tube outside of the anode plate (4) and along the beam outlet window (20) of the tube forming narrow gaps (18, 19), and is then passed out radially via at least one baffle plate (21) which is arranged on the tube (2) and engages in a correspondingly designed gap in the guide body (12). The high-voltage parts have an insulating gas applied to them, which is physically not separated from the liquid coolant in the source housing (1).

摘要： An X-ray source has an emitter for the production of an electron beam and an anode on which the electron beam strikes in an X-ray focal spot, and a magnet system that produces a dipole field and a quadrupole field that is superimposed on this dipole field, for deflecting and focusing the electron beam onto the anode. In addition, an arrangement is provided that operates together with the magnet system for the adjustment of the size of the X-ray focal spot. This arrangement, in order to set a desired size of the X-ray focal spot, adjusts the quadrupole field in so that the X-ray focal spot has a width corresponding to the desired size of the X-ray focal spot, and supplies to the magnet system a wobble signal that influences the dipole field, this wobble signal effecting a periodic displacement of the electron beam in a direction transverse to the extension of the width of the X-ray focal spot. This gives the focal spot an effect length, resulting from the deflection and measured in the direction of the deflection, to achieve a particular ratio of the effective length to the width of the X-ray focal spot.
