AI Technical Summary

Technical Problem

Existing technologies lack methods for evaluating low-pressure discharge voltage in narrow-gap structures, making it difficult to accurately explain and predict low-pressure discharge phenomena under narrow-gap conditions.

Method used

By determining the basic parameters, calculating the secondary electron emission coefficient and the ion-enhanced field emission electron coefficient, considering the multipath effect, optimizing the calculation of the narrow gap discharge voltage, introducing the ion bombardment and field electron emission mechanism, and correcting the traditional Paschen theorem.

Benefits of technology

A narrow-gap low-pressure discharge voltage value was obtained that is more consistent with the experimental results, thus improving the accuracy and prediction precision of the narrow-gap discharge voltage threshold.
