Definition of Thermal management in X-ray tubes
Check what you remember
Read the wording for your board, then hide it and explain Thermal management in X-ray tubes in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The anode rotates so the electron beam strikes a moving area, preventing local overheating and allowing a higher tube current and continuous operation.
