Beam induced transient vacuum instability in H- beam

Research output: Contribution to conference › Paper › peer-review

Abstract

When high current beam is transported through a vacuum channel, vacuum instability can develop due to desorption caused by ion/electron bombardment of the walls. In case of pulsed beam one can have situation when stability conditions are satisfied in average, while violated during the pulse. This effect can cause additional losses for H- beams due to stripping on the tail of the pulse. Expression for instability threshold is derived and estimations are done for the SNS MEBT beam parameters.
