Abstract
The ionization and attachment coefficients in SF6-He and SF6-Ne gas mixtures have been measured by the steady state Townsend method over the range 7. 52≤E/p≤94. 0kV/(mm ·MPa). The limiting E/p values of SF6-He and SF6-Ne in various mixing ratio are proposed
and insulating properties of SF6-He and SF6-Ne are analysed.
