Abstract :
The NIST electronic kilogram experiment is being completely rebuilt into a vacuum chamber within a specially designed laboratory room. Major renovations include reference mass positioning equipment, structural alignment flexures, and a redesigned inductive coil. The goal is less than 10 nW/W uncertainty. Preliminary data on measurement capabilities are expected.
