A Realistic Proportional-Integral RF Feedback Model for Longitudinal Beam Dynamics Simulation
Tianlong He, Wenshu Liang, Jincheng Xiao +1
Modern fourth-generation storage ring light sources predominantly utilize digital I/Q-based proportional-integral (PI) feedback for their radio-frequency (RF) systems. This paper i…
Crab-waist interaction region design and integration for the Super Tau-Charm Facility
Linhao Zhang, Tao Liu, Ye Zou +10
The Super Tau-Charm Facility (STCF) is a new-generation collider proposed in China, designed to operate in the center-of-mass (CoM) energy range of 2-7 GeV. To achieve the…
Conceptual Design Report of Super Tau-Charm Facility: The Accelerator
Jiancong Bao, Anton Bogomyagkov, Zexin Cao +93
Electron-positron colliders operating in the GeV region of center-of-mass energies or the Tau-Charm energy region, have been proven to enable competitive frontier research, due to…
Optics design of the Super Tau-Charm Facility collider rings
Ye Zou, Linhao Zhang, Tao Liu +16
The Super Tau-Charm Facility (STCF), China's next-generation electron-positron collider, targets an unprecedented luminosity exceeding 5x10^34 cm^-2 s^-1 at a center-of-mass energy…
Impact of coherent wiggler radiation impedance in Tau-Charm factories
Tianlong He, Ye Zou, Demin Zhou +6
Coherent synchrotron radiation (CSR) has long been recognized as a significant source of longitudinal impedance driving microwave instability in electron storage rings. In the purs…
Phantom Domain Finite Element Method: A novel approach for heterogeneous materials
Tianlong He, Philippe Karamian-Surville, Daniel Choï
In this paper, we introduce the Phantom Domain Finite Element Method (PDFEM), a novel computational approach tailored for the efficient analysis of heterogeneous and composite mate…
