What is it about?
To test a detonator, it is given a specified stimulus (eg a specified voltage) and the detonator either NOGOs or GOs. For safety assurance, the detonator has be demonstrated safe at low voltages, such as those generated by electrostatic discharge. This involves showing that No-Fire Threshold (NFT) is above some specified critical value. Roughly speaking, the NFT is the voltage where the probability of GO is 0.001. With no limit on resources, we would do thousands of tests at very low voltages to estimate the NFT, with roughly 999 out of every thousand being NOGO, and 1 out of a thousand being GO. In practice, we can do much better by choosing the voltage level which maximizes the expected gain in information about the NFT. This voltage will tend to be much larger than the NFT, because almost no information is gained by doing a test at the NFT and observing a NOGO outcome. Our paper explains how to compute the voltage level which maximizes the expected gain in information, for any quantity of interest.
