Beam dynamics in the spiral line induction accelerator

Simulation studies of the spiral line induction accelerator (SLIA) experiments have been performed. Equilibrium in the solenoidal field has been studied and a generalization of the K-V distribution has been found which gives a better equilibrium for the SLIA parameters, though these qualities are not likely to be produced experimentally. Hoop force corrections in the bends of the SLIA have been calculated and it is shown that the achromatic properties of the design are preserved. Diamagnetic effects on the vertical field index are not important. A scheme for matching the beam on and off the stellarator windings has been devised which uses a single thick quadrupole lens on each end of the stellarator, greatly reducing emittance growth.<>
