With gold film as anode the transition from equilibrium to non-equilibrium ionization has been investigated and where possible new values for the primary and secondary ionization coefficients have been obtained. With gold film as cathode the total ionization is enhanced considerably at low values of E/p<or approximately=100 where decreases in threshold breakdown voltage as large as 1800 V have been noted. A variation of the secondary coefficient with electrode separation and a marked sensitivity to impurity in the gas sample have been observed. It is shown that this is consistent with secondary electron emission at the gold film by metastable (A3 Sigma u+) particles which diffuse to the boundary surface after production by electron impact excitation in the gas.Read More
