ILSE combiner study
In a heavy ion inertial fusion (HIF) driver, the beam energy and current are increased several orders of magnitude from the injector to the final focus system. At low and high energy stages of the driver, electrostatic and magnetic focusing transport channels, respectively, can be used. At the electric-to-magnetic transition point, the beams may be combined to reduce the transverse dimensions of the system, which could have significant impact on the driver cost. In a presently envisioned combiner, four beams are brought together transversely into a single transport channel. A matching section follows the combiner in order to provide a smooth transition to the subsequent magnetic transport channel. This report summarizes a conceptual design study of possible combiner configurations for the proposed Introduction Linac Systems Experiment (ILSE). The conceptual design study includes subjects such as the expected technical difficulties, predicted emittance growth, particle loss, effect of geometric and chromatic aberrations, and the sensitivity of emittance growth on the initial beam position and angle errors.
