Design of the Tsinghua Tabletop Kibble Balance
Shisong Li, Yongchao Ma, Wei Zhao +2
The Kibble balance is a precision instrument for realizing the mass unit, the kilogram, in the new international system of units (SI). In recent years, an important trend for Kibbl…
Multifocal laser direct writing through spatial light modulation guided by scalable vector graphics
Linhan Duan, Yueqiang Zhu, Haoxin Bai +4
Multifocal laser direct writing (LDW) based on phase-only spatial light modulator (SLM) can realize flexible and parallel nanofabrication with high throughput potential. In this in…
An analytical algorithm for 3D magnetic field mapping of a watt balance magnet
Zhuang Fu, Zhonghua Zhang, Zhengkun Li +4
A yoke-based permanent magnet, which has been employed in many watt balances at national metrology institutes, is supposed to generate strong and uniform magnetic field in an air g…
The NIM Inertial Mass Measurement Project
Shisong Li, Zhonghua Zhang, Qing He +4
An inertial mass measurement project, which is expected to precisely measure the Planck constant, , for possible comparisons with known gravitational mass measurement projects,…
