At these pressures , the electron is more likely to have an ionizing collision
between the electrodes , and indeed , the plasmas do become denser and more
conductive at higher pressures . However , high - pressure operation also results
in ...

The large cross - sections at high electron energy would rapidly damp or degrade
the higher velocity electrons , resulting in a lower electron temperature . Indeed ,
this is often observed in processing plasmas . The collision rate for electrons ...

In practice , when compared to experimental results , often the conductivity is
significantly higher , often by two to three orders of magnitude . A semiempirical
relation for this much higher conductivity was developed by Bohm ( 11 ] , who
found ...
