摘要

<strong>Context and Background</strong>: In this research, we investigate the interaction of X-rays with a capacitor by studying the voltage established in the capacitor during the illumination. <strong>Motivation</strong>: We aim at verifying that the total energy conserved in the interaction is <span style="white-space:nowrap;"><i></i></span><i>Pτ, i.e.<span style="white-space:nowrap;"></span></i> the product of the average power <span style="white-space:nowrap;"><i></i></span><i>P<span style="white-space:nowrap;"></span></i> times the period τ of the X-rays. <strong>Hypothesis</strong>: Our investigation relies on the hypothesis that the voltage responsivity π<span style="white-space:nowrap;"><i></i></span><i>_{V<span style="white-space:nowrap;"></span>}</i> of the capacitor should be small, according to previous research. The parameter π<span style="white-space:nowrap;"><i></i></span><i>_{V<span style="white-space:nowrap;"></span>}</i> is the ratio between the voltage produced and the average power <span style="white-space:nowrap;"><i></i></span><i>P<span style="white-space:nowrap;"></span></i> of the X-rays, and measures the performance of the capacitor in response to the X-rays. <strong>Method</strong>: We measure the voltage produced by the capacitor in response to the X-rays, and then determine the average power <span style="white-space:nowrap;"><i></i></span><i>P<span style="white-space:nowrap;"></span></i> of the X-rays according to a procedure already assessed with infrared and visible light. <strong>Results</strong>: In our experiments, <span style="white-space:nowrap;"><i></i></span><i>P<span style="white-space:nowrap;"></span></i> turns out to be in the range between 10^{<span style="color:#4F4F4F;font-family:-apple-system, " font-size:16px;white-space:normal;background-color:#ffffff;"="">-</span>3}W to 10⁰ W. Our procedure enables us to unveil the relationship between the average power P and the effective dose, an important operating parameter used to measure
