  • Abstract
    In the present study, the growth of an externally triggered avalanche in SF6 was voluntarily modified using a substantial amount of moisture content. Results show that contamination did not increase the number of initially released photoelectrons but enhanced the avalanche growth rate. The avalanche current amplitude was found to increase with the contamination level, which permitted measurements at higher pressures compared to pure SF6. However, even with 15% water contamination, it was possible to extend the measurement pressure limit only from about 30 to 50 Torr
