| Zusammenfassung |
| Discharge experiments were carried out at the Technical University of Eindhoven in 2013. The experimental set-up was designed to search for electrons produced in meter-scale sparks using a 1 MV Marx generator. Negative voltage was applied to the HV electrode. Five thin (1 mm) plastic detectors (5 cm2 each) were distributed in various configurations close to the spark gap. Earlier studies have
shown (for HV negative) that X-rays are produced when a cloud of streamers has developed 30-60 cm from the negative electrode. This indicates
that the electrons producing the X-rays are also accelerated in this location, probably in the strong electric field from countestreaming streamers of opposite polarity.
Comparing our measurements with modeling results we find that 200-400 keV electrons produced about 30-60 cm from the negative electrode is the most likely
source of our measurements. |
