Measurement of Ionization and Attachment Coefficients in SF 6 and Xenon Gas Mixtures

The Townsend first ionization coefficient α, electron attachment coefficient η and effective ionization coefficient α (=α-η) in SF 6 and xenon gas mixtures were measured by the steady-state Townsend method for 22.6 \leqslant E / p \leqslant94 V·mm -1 ·kPa -1 and mixture ratios of 10:90, 25:75, 50:50...

Description
Summary:The Townsend first ionization coefficient α, electron attachment coefficient η and effective ionization coefficient α (=α-η) in SF 6 and xenon gas mixtures were measured by the steady-state Townsend method for 22.6 \leqslant E / p \leqslant94 V·mm -1 ·kPa -1 and mixture ratios of 10:90, 25:75, 50:50, 75:25 and 90:10. The limiting E / p in SF 6 -Xe, ( E / p ) lim , which represents E / p for α/ P = n / P , was derived from the pre-breakdown current growth measurements, which varies approximately linearly with SF 6 concentration in the SF 6 -Xe gas mixtures.
