Description
A prototype Canadian compact accelerator-driven neutron source (PC-CANS) is proposed for installation at the University of Windsor. PC-CANS is designed to produce neutrons for materials science and BNCT applications, as well as protons for PET isotope production. The source employs a high-intensity compact proton RF linear accelerator delivering a peak current of 20 mA with a 5% duty factor at 10 MeV to the target. The accelerator consists of a short radio-frequency quadrupole (RFQ) accelerating to 3 MeV, followed by a drift tube Linac (DTL) structure up to 10 MeV. Several room-temperature DTL variants, including Alvarez, and using H-mode DTL with alternating phase focusing (APF), combined zero degree structure (KONUS), and negative synchronous phase (NSP) beam dynamics are studied at 352.2 MHz, along with a superconducting half wave resonator (HWR) option at 176.1 MHz.
This paper presents a comparative beam dynamics study of the various structures. The comparison includes beam transmission, longitudinal and transverse emittance growth, Linac length, and longitudinal and transverse phase-space acceptance.
