A rotating anode promotes cooling between exposures by distributing the intense beam from the cathode over the surface of the anode. A rotating anode tube lasts a lot longer than a stationary x-ray tube.
In X-ray tubes, electrons are emitted from a cathode source to a anode target through a process called thermionic emission. Electrons are then accelerated towards the anode target via a potential energy difference between the cathode and anode. The interaction between the accelerated electrons and atoms in the anode target causes the emission of X-ray. Efficiency of the X-ray tube is impaired by the kinetic energy of the accelerated electrons being loss as heat and only 1% of the remaining energy is used to emit X-ray.
The x-ray tube target is rotated to reduce wear and tear on the anode and to keep the anode from overheating.

to produce an x ray radiation
During X-ray exposure, electrons flow from the cathode to the anode in the X-ray tube. This flow of electrons generates X-rays by interacting with the anode target material, producing high-energy photons that are used for imaging purposes.
when the cathode filament emits the electron and because of the high vaccum inside the tube with a high voltage who is applied on anode (the destination) the electron will accelerate to the anode and the anode will emits the x-ray photon directly after strike of the mentioned electron. the power of x-ray or peneration is determined of the anode high voltage.
X-rays result when high energy electrons slam into stuff, mostly metals. We accelerate electrons by using high voltage. An X-ray tube has high voltage applied between a cathode and an anode. The cathode, from which the electrons originate, is negative, and the anode, which is positive is the "target" for those electrons. The electrons, having been accelerated by the high voltage, "slam into" the anode, and generate the X-rays. The anode is the source of the X-rays.
The strength of an xray is refered to as kVp, and it varies depending on the speed of the electrons before they hit the anode inside the x-ray tube.
The normal anode angle in a diagnostic x-ray tube is usually around 12-17 degrees. This angle helps to distribute heat and increase the efficiency of x-ray production by allowing for better dissipation of heat generated during the x-ray process.
