Compatibility and Accuracy Verification of CADmesh-Based Complex Geometry Modeling in Geant4
Shiwei Jing, Weiyang Zhang, Shengduo Liu +11
Geant4 Monte Carlo simulation relies on the Constructive Solid Geometry (CSG) method for complex geometric modeling. This method has low efficiency and a high application threshold…
A Method for Neutron-Gamma Pulse Shape Discrimination of CLYC Detector Based on a Gated Residual-Linear Attention Network
Shiwei Jing, Shengduo Liu, Weiyang Zhang +11
The discrimination of neutron and gamma pulse shapes is a key technology in fields such as nuclear safety monitoring and radiation assessment. An enhanced recursive gated cyclic re…
Optimized design of a Penning ion source for sealed neutron tube
Shiwei Jing, Jia Song, Shengduo Liu +7
Sealed neutron tubes have a wide range of applications, and the ion source is their core component. Penning ion sources commonly suffer from issues such as uneven magnetic field di…
Trapping of electrons and ions in a dual-frequency Paul trap
Vladimir Mikhailovskii, Natalija Sheth, Guofeng Qu +12
We demonstrate the operation of a dual-frequency Paul trap and characterize its performance by storing either electrons or calcium ions while applying two quadrupole fields simulta…
Levitated Sensor for Magnetometry in Ambient Environment
Wei Ji, Changhao Xu, Guofeng Qu +1
Levitated particle systems have gained significant attention as a rapidly advancing platform for precision sensing, offering low-loss, highly isolated environments by eliminating m…
