Title: Suppression of transverse beam breakup modes in an induction accelerator by gas focusing

Technical Report ·
DOI:https://doi.org/10.2172/5346497· OSTI ID:5346497

The effect of beam-generated positive ions on the beam-breakup instability in linear electron accelerators is calculated using simple models. The strongly nonlinear dependence of the ion focusing force on radius makes a complete suppression of the mode growth possible, in contrast to solenoidal focusing. The predicted gas pressures for significant stabilization of the mode growth in a machine configuration like ATA is relatively low (10/sup -5/ to 10/sup -4/ torr), even for high-Q modes.
