Abstract
A method and device for control of an electron beam flux, electron spot size, and/or electron spot location. Electromagnetic radiation from an anode of the x-ray tube can be focused on a detector. The detector can send a signal to a control module based on the electromagnetic radiation focused on the detector. The control module can control the electron beam with a beam control device and/or a current control device. The signal can also indicate anode temperature at the electron spot.
