| Abstract | ||
| The energy electron distribution function at a particular reduced electric field E/p (where E is the electric field and p is the gas pressure) for SF6+He and SF6+Ar mixtures has been studied. The distribution function has been calculated as a function of percentage mixture ratio (k) ranging from zero (pure SF6) to 100% (for He or Ar) at (E/p)crt. On the other stage, these distribution functions are also studied as a function of (k) at a particular (E/p)crt. under which the breakdown occurs for the same gas mixtures. The (E/p)crt calculation is adopted to explain the discrepancy of the distribution function for gas mixtures. It is also found that the distribution function for gas mixtures at (E/p)crt. and for any value of (k) are identical. | ||
