Abstract:

This report describes the experimental determination of the formative time lag data for hydrogen and helium. For subnanosecond risetime pulses, there are typically very few free electrons in the discharge space generated through ionization by external radiation sources such as cosmic rays. Therefore, electrical field emission plays a very important role in these discharges. This report also includes a theoretical determination of the effective electric field for an arbitrary electromagnetic pulse. The effective electric fields for a variety of pulse shapes are calculated for the first time.
