A Compact Magnet System for the Tsinghua Tabletop Kibble Balance
Yongchao Ma, Nanjia Li, Weibo Liu +4
Although the so-called magnetic geometrical factor, , of a Kibble balance does not appear in the Kibble equations, it offers the precision link between electrical and mechanica…
A Bi-polar Current Source with High Short-term Stability for Tsinghua Tabletop Kibble Balance
Kang Ma, Xiaohu Liu, Wei Zhao +2
A high-precision current source, capable of supporting weighing measurements with a relative uncertainty at the level, is essential for Kibble balance experiments. Howeve…
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…
Designing Model and Optimization of the Permanent Magnet for Joule Balance NIM-2
Qiang You, Jinxin Xu, Zhengkun Li +1
Permanent magnets with yokes are widely used in the watt and joule balances to measure the Planck constant for the forthcoming redefinition of the unit of mass, the kilogram. Recen…
A Five-Freedom Active Damping and Alignment Device Used in the Joule Balance
Jinxin Xu, Qiang You, Zhonghua Zhang +2
Damping devices are necessary for suppressing the undesired coil motions in the watt/joule balance. In this paper, an active electromagnetic damping device, located outside the mai…
Field representation of a watt balance magnet by partial profile measurements
Shisong Li, Jiansheng Yuan, Wei Zhao +1
Permanent magnets with high-permeability yokes have been widely used in watt balances for supplying a robust and strong magnetic field at the coil position. Subjected to the mechan…
