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

Abstract

Taking advantage of the 0° synchronous phase, the KONUS ("Combined 0° Structure" translated from German "Kombinierte Null Grad Struktur") 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 room temperature 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 young superconducting CH (Crossbar H-Type) structure for accelerating very high intensity beams is being presented. The efficiency of the new solution has been shown by the systematic design studies performed for a 150mA, 6MW deuteron linac.

Combined zero degree structure beam dynamics and applications

“…KONUS structures will need further improvement and an advanced collimator concept to be ready for applications of that kind. One KONUS layout study for 150 mA deuteron beams and with superconducting magnetic solenoid focusing and superconducting CH cavities was already performed successfully and seems promising [23].…”
