Design of a Miniature Kibble Balance for Kilogram-Scale Mass Calibration -- KBmini
Shisong Li, Nanjia Li, Weibo Liu +3
Tabletop version Kibble balances are a significant developing trend for mass realizations following the revised International System of Units. A key innovation through the miniatur…
An Approach for Restoring Magnetic Field Uniformity in Openable BIPM-Type Kibble Balance Magnets
Nanjia Li, Weibo Liu, Yongchao Ma +3
The Kibble balance realizes the kilogram by linking mechanical and electrical quantities via a magnet system. In an improved BIPM-type magnet design by Tsinghua University, an open…
Updates on the Tsinghua Tabletop Kibble Balance
Shisong Li, Yongchao Ma, Kang Ma +7
With the adoption of the revised International System of Units (SI), the Kibble balance has become a pivotal instrument for mass calibrations against the Planck constant, . One…
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…
