Efficient solution for accelerating very high intensity beams in the low and medium energy regime

Abstract

Taking advantage of the 0° synchronous phase, the kombinierte null grad struktur (KONUS) beam dynamics strategy enables long accelerating sections with lens-free slim drift tubes in the low and medium energy regime. It has successfully realized worldwide many normal-conducting H-type linacs with compact layouts and good beam performance. In this paper, a further development of this solution, i.e., to combine the KONUS dynamics with the recently developed superconducting CH structure for accelerating very high intensity beams, is presented. The efficiency of the new solution has been shown by systematic design studies performed for a 150 mA, 6 MW deuteron linac.
