Abstract: The initiation capability of a microdetonator 0.9 mm in diameter and 3 mm in height is studied. The critical height of the lead azide explosive is 1.8 mm. The optimal ratio of the heights of the primary and secondary explosives in a microdetonator is determined to be 0.7–2.3. At an identical ratio of the primary and secondary explosive heights, the output pressure changes from the highest to the lowest value in the sequence from CL-20 to HMX and then to RDX.

Keywords: microdetonator, manganin gauge, output pressure, initiation.
