dc.description.abstract | Sheet electron beams focused by periodically cusped magnetic (PCM ) fields are stable against
low-frequency velocity-shear instabilities (such as the diocotron mode). This is in contrast to
the more familiar unstable behavior in uniform solenoidal magnetic fields. A period-averaged
analytic model shows that a PCM-focused beam is stabilized by ponderomotive forces for short
PCM periods. Numerical particle simulations for a semi-infinite sheet beam verify this
prediction and also indicate diocotron stability for long PCM periods is less constraining than
providing for space-charge confinement and trajectory stability in the PCM focusing system. In
this article the issue of beam matching and side focusing for sheet beams of finite width is also
discussed. A review of past and present theoretical and experimental investigations of
sheet-beam transport is presented. | en_US |
