Consider an x-ray tube in which electrons are accelerated by a constant high voltage of 250 kV. If the electron beam current is 10 mA, calculate the x-ray energy flux (energy fluence rate) at a distance of 1 m from the tungsten anode target. Neglect absorption by the glass, and assume that the bremsstrahlung is emitted isotropically.
to demonstrate the electrostatic shielding
