What is it about?
Flash X-ray systems are commonly used in laboratory settings where a short burst of X-rays is needed to see inside an object during an experiment. This paper examines several commercially-available sensors as a way to determine exactly when and for how long those X-ray pulses occur.

Why is it important?
This work examines several low-cost commercially-available photodiodes for use as direct X-ray detectors. Traditionally, short X-ray pulses may be measured in laboratory settings using a combination of a scintillator and a photodiode, but it is often difficult to record weak X-ray pulses this way. Our findings show that we can repeatably and directly measure short nanosecond duration X-ray pulses using a photodiode alone. This work provides a simple and effective method for determining the timing of X-ray pulses in any flash X-ray system.
