Title: Achievable Accuracy and Precision of Timing with Dynasen Piezo Electric Pins

Abstract

Piezo electric pins from Dynasen are often used in the shock and detonation community for triggering or timing purposes. The purpose of this memorandum is to document factors that affect the accuracy and precision that can be reasonably expected from using the pins. Three different pin types were used and repetition of ablative laser pulses were used to measure the time variation both for the same pin and similar pins from a lot. It was established that the standard deviation for a common shock between all pins was 190 ps and that the maximum variance between any two similar pins was 960 ps. Thus it is clear that uncertainty in the pin location, cable lengths and electrical signal analysis are likely to affect accuracy and precision from piezo pin-based measurements far more than inherent pin-to-pin variation. However, these measurements also demonstrate that with suffcient experimental care, these off-the-shelf piezo pins are capable of nanosecond accuracy and precision.
