Notes:
An experimental program is described in which the capacitor-discharge initiation characteristics of a detonator containing a vacuum-deposited thin-film chromium bridge were studied. The objective of the effort was to define the conditions that would result in overall function times of 10 μs or less. The threshold initiation energy of the detonator was in the range of 11.5 mJ-20.0 mJ. Consistent performance was obtained from a firing energy of 54 mJ, which was achieved by a 5-μF capacitor charged to 147 V. Under these conditions, the average overall function time was 4.2 μs, with a standard deviation of 0.2 μs. Other tests showed that at higher capacitances and lower voltages the function time increased substantially and became more nonreproducible, even though the stored energy was considerably above the threshold value.
