Abstract

A type of Kibble (watt) balance that uses unconventional modes of operation was designed and constructed at the National Physical Laboratory. Theory predicts that this type of balance will be simpler to construct and operate due to the removal of many alignment problems. The balance uses a compact twisted pair coil in both the weighing and moving modes. This paper describes the design and manufacture of the coil and presents results of outgassing measurements made on the coil using a vacuum mass comparator.
