1. An X-ray source configured to emit X-ray radiation upon interaction between an electron beam and a liquid jet target, the X-ray source comprising:
an electron source comprising a cathode configured to emit electrons and an anode electrode configured to accelerate the emitted electrons to form the electron beam;
an adjustment means configured to adjust a relative orientation between the anode electrode and the cathode of the electron source;
a focusing means configured to focus the electron beam on the liquid jet target in accordance with a focusing setting;
a beam orientation sensor arranged to generate a signal indicating an orientation of the electron beam relative to a sensor area; and
a controller operably connected to the focusing means, the beam orientation sensor and the adjustment means;
wherein the controller is configured to cause the adjustment means to adjust the relative orientation between the anode electrode and the cathode so that the signal received from the sensor changes within a pre-determined interval when the focusing setting is changed.
