Outline of Final Research Achievements

It has widely been accepted that the faster the approach speed of electrostatic discharge generators (ESD guns) is, the shorter the spark length becomes. In this study, to investigate this relation quantitatively, we developed a setup for electronically measuring a spark length in air discharges of ESD guns. As a result, we found that the measurement errors of movement distances were under 4% and the error of collision time was about +1.2ms. Moreover, it was also found that measured spark lengths agree well with those calculated by using an empirical formula derived from the Paschen’s law and they have the same tendency with respect to approach speeds and charge voltages as other researcher’s results and our previous studies .From above mentioned results, it was completed constructing the measurement system for spark length.
