  • Abstract
    A new type of moving-coil Watt balance with a compact design is under construction at the Swiss Federal Office of Metrology (OFMET). Recently, several key components of the system have been characterized. In this paper, a detailed description of the mechanical setup, an assessment of the magnet, the optical system for speed measurement and regulation, and the programmable Josephson voltage standard are reported
