| MOPB031 | Studies on Beam Injection System for Wuhan Advanced Light Source Storage Ring | storage-ring, emittance, dynamic-aperture, septum | 73 |

| Wuhan Advanced Light Source is the low-energy 4th generation advanced light source, proposed by Wuhan University. It includes a 1.5 GeV of full-energy LINAC injector, a 180 m circumference of low-emittance storage ring, and a series of state-of-the-art beam lines. The standard 7BA magnetic focusing structure is adopted for the storage ring to lower the beam emittance and the lattice has been well- designed and optimized by multiple-objective genetic algorithm to maximize the dynamic aperture and energy acceptance. The dynamic aperture of the storage ring at injection can reach up to 10 mm in the horizontal plane, which makes the off-axis beam injection method possible. An off-axis beam injection scheme based on the pulsed nonlinear magnet is to be employed for the storage ring. Detailed studies about the beam injection scheme, including the beam optical design, nonlinear magnet design and optimization, have been performed and multi-particle simulations have also been carried out to study the beam injection procedure. | |||

| MOPB036 | Compact Accelerator Light Source for Industrial Applications | radiation, synchrotron, storage-ring, synchrotron-radiation | 82 |

| Synchrotron radiation has great application potential in industry. However, the large scale of modern light source has limited it from popular use. Compact accelerator light source has many virtues such as small scale, cost effectiveness, maintenance convenience, etc., which make it a main solution of light source application in industry. The idea has attracted great interests from many institutes, and much effort has been put into its research and development. In this paper we present a design of compact accelerator light source with very small scale. The lattice is very simple to ensure its compactness, while the beam parameters remain flexible to industry needs. | |||

Funding: Work supported by National Natural Science Foundation of China (No.12075131) Xi’an Proton Application Facility (XiPAF) has been operational since 2020, which can accumulate 2e11 protons after injection and 1e11 protons after acceleration. In this paper, we have investigated the XiPAF synchrotron nonlinearity by simulation and experiments, the beam loss occurs with resonance vx+2vy=5 in the absence of space charge, and resonance 2vx-2vy=0 in the presence of space charge. The stripping foil also plays an important role due to its multiple scattering effect and ionization energy loss effect. |

| TUPB021 | The Design of a Proton-Heavy Ion Hybrid Synchrotron Upgraded from XiPAF Proton Ring | proton, synchrotron, heavy-ion, extraction | 129 |
|
|||
| Xi’an 200MeV Proton Application Facility (XiPAF) has been basically completed at the end of 2020, providing proton beams of 10 to 200 MeV for space radiation effect studies on electronics. To expand its capabilities, XiPAF is undergoing an upgrade to deliver multiple ion species, from proton to Bismuth ion. The upgrade focuses on three aspects. First, the original negative hydrogen linear injector will be remodeled to a proton linear injector. Second, a heavy ion linear injector will be added. Third, the existing proton ring will be retrofitted into a hybrid proton-heavy ion synchrotron. Correspondingly, the beam transport lines will also be modified. This paper details the considerations and physical designs for upgrading the synchrotron. Within the scope, we discuss the challenges and solutions in transforming a specialized proton synchrotron into a multi-ion accelerator under the constraints of existing plant layout and reuse of existing equipment. | |||
