"Sprites" are #D created that move upstream against the direction of beam #D propagation use the beam as a moving waveguide in effect. #D The sprites are unstable and evaporate if removed from this #D special environment. Sprites are a fascinating phenomena and #D show up frequently in beams of this type. #D #D #D Michael Sweney December 1999 #L .AB25.BA$AB.A23.A.BA$AB..B..BA13.AB..B..BA$3.BB..BA13.AB..BB$..AB.ABB. #L B11.B.BBA.BA$..AA..AA..A9.A..AA..AA$..AB.ABB.B11.B.BBA.BA$3.BB..BA13.A #L B..BB$AB..B..BA13.AB..B..BA$AB.A23.A.BA$.AB25.BA
