Matching and transport of beams in a continuously twisted quadrupole channel

Description

Twisted quadrupole (stellarator) focusing can reduce dispersion in the bends of a recirculating accelerator, such as the Spiral Line Induction Accelerator (SLIA) under development at Pulse Sciences. Envelope oscillations caused by guide field/stellarator transitions add free energy to the beam which can couple into the beam emittance. This effect can be reduced by phase space matching of the beam at the transitions. The authors present experimental results on the coupled 4-D problem of envelope matching into a straight helical quadrupole channel, compare these results against envelope code predictions, and discuss expected benefits from such matching in a few-turn accelerator system
