| Abstract: | The analytic solution of the average electron velocity vector W(t) of an electron swarm in gas under ac electric and dc magnetic fields (E(t) and B, respectively) in a constant-collision-frequency model is extended to cover not only the known case of a right crossing angle (E(t) perpendicular to B) but also the cases of arbitrary crossing angles (E(t) (sic) B). The x, y, and z components of W(t) are obtained as explicit formulae with the following parameters: the amplitude E of E(t), the angle theta between E(t) and B, the angular frequency omega(E) of E(t), the cyclotron angular frequency omega(B) (subject to the strength B of B), and the electron collision frequency nu. A basic feature that W(t) draws elliptic locus in velocity space is unchanged even under E(t) (sic) B, but the plane including the locus may tilt when omega(E), omega(B), or nu varies. The derivation of W(t) based on the analytic solution of single electron motion is detailed and fundamental behavior of the W(t) loci is observed to understand the electron transport under E(t) x B fields. |
