Abstract
A compact accelerator-driven neutron source is proposed at
Sino-French Institute of Nuclear Engineering and Technology, Sun
Yat-Sen University, called Sun Yat-Sen University Proton Accelerator
Facility (SYSU-PAFA). The proton accelerator is composed of a proton
electron cyclotron resonance source, a four-vane radio frequency
quadrupole (RFQ), and an alternative phase focusing drift tube linac
(APF-DTL). It can accelerate 10 mA proton beam to 8 MeV. Due to
the high current, beam matching is particularly important. In order
to achieve beam matching between various components, beam transport
sections are needed. The beam transport line is divided into three
segments. The Low Energy Beam Transport (LEBT) ensures that the beam
parameters are matched before entering the RFQ. The Medium Energy
Beam Transport (MEBT) segment efficiently transfers the beam between
the RFQ and DTL. The High Energy Beam Transport (HEBT) focuses on
transporting the beam to the targets. The design goal of beam
transport line is as short as possible while ensuring high
efficiency of beam transportation. SYSU-PAFA has an overall
transmission efficiency of 99%, with optimal transverse matching
conditions between beam transport and RFQ or DTL accelerators. The
efficient use of solenoids and magnets allows for a compact
transmission section, resulting in a total length of 13.6 meters,
shorter than most accelerators at the same beam energy. This paper
will provide the detailed beam dynamics of the compact accelerator.
