What is it about?
Detonating explosives have a small region behind the shockwave where chemical reaction occurs. This region is difficult to measure because of its size and speed. This work presents a new way of overcoming these problems by probing it with a high frequency electrical signal.

Why is it important?
The method presented in the paper provided measurements for a particular explosive that were considered especially difficult to obtain. It should therefore be applicable to other explosives. The technique has a lower cost than many alternatives, and has potential to be further improved.
