Abstract
An x-ray radiation stabilization system is provided including an x-ray tube (,) which emits x-ray radiation (,). The x-ray tube (,) has an anode (,), a cathode (,), and a vacuum envelope (,) which houses the anode (,) and the cathode (,). A high-voltage generator (,) is connected to the x-ray tube (,). It supplies a high-voltage electric potential between the cathode (,) and anode (,) such that an electron beam flows therebetween. The electron beam strikes the anode (,) producing the x-ray radiation (,). A reference radiation detector (,) samples a representative portion of the x-ray radiation (,) emitted by the x-ray tube (,) and generates an error signal in response to an intensity of the sampled x-ray radiation (,). A feedback circuit (,) is connected between the reference radiation detector (,) and the high-voltage generator (,). The feedback circuit (,) processes the error signal and in response thereto directs the high-voltage generator (,) to adjust the high-voltage electric potential supplied to the x-ray tube (,) so that in the x-ray radiation (,) ripple having a predetermined frequency range is substantially canceled.
