Figure 3.12: <strong>Multipactor</strong> thresholds <strong>in</strong> low pressure argon for the two lowest<br />
order modes (N = 1 <strong>and</strong> N = 3) with µ = 0.75 <strong>and</strong> µ = 0<br />
respectively. In this case, the second cross-over energy is about<br />
7 times greater than <strong>in</strong> Fig. 3.11. Parameters used are: W1 =<br />
170 eV , W0 = 4 eV, σse,max(0) = 1.3, ɛ0 = 0, pd = 25 Pa·mm<br />
for N = 1, <strong>and</strong> pd = 15 Pa·mm for N = 3.<br />
