Abstract :
In the frame of the future redefinition of the International System of Units (SI), the unit of mass represents probably the biggest challenge. After the publication of the results from Mark I experiment, the effort is now concentrated on the development of the Mark II system. In this paper, we review the design and present the first tests of the individual components.
