Abstract
Pulsed x-ray dose measurements have been carried at maximum x-ray energies from 40 to 120 KeV out by using a single crystal epitaxial diamond sample grown by chemical vapor deposition (CVD). Delivered doses were between 0.1 and 10 mGy and pulse duration times between 0.01 and 0.5 s. Values of dose linearity index very close to 1 (between 1.02 and 1.07) at increasing x-ray energies and pulse decay times between 15 and 20 ms were obtained. The reproducibility was very good with no memory effects. CVD homoepitaxial diamond results to be very promising for x-ray diagnostic applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
