Abstract

We report the status and progress of Korea Research Institute of Standards and Science (KRISS) in pico-newton standard force realization. To produce and measure discrete magnetic force on a superconducting ring in proportion to the number of flux-quantum, an instrument and facilities are being developed to provide multi-conditions such as low temperature, high field-gradient, high vacuum, vibration isolation, and so on. Design and construction of sub-systems are presented as well as expected and tested specification for each sub-system.
