Measuring the Radiation Energy Density of a Pulsed X-Ray Source

A method is presented for measuring the energy density of X-ray pulses with a duration of approximately 200 ns from a source with an energy of 2–3 J in its discharge circuit. A bismuth germanate (BGO) scintillator crystal is used for measurements. The absolute calibration of the energy scale has been carried out by measuring the amplitude spectrum of cosmic muons. The energy flux of an X-ray pulse, measured at a distance of 1 m from the anode of the source, is 20 GeV/cm2.
