Abstract
Frequency shifts due to the microwave distributed cavity phase (DCP) have been evaluated for the NRC-FCs2 atomic fountain primary frequency standard of the National Research Council Canada. NRC-FCs2 utilizes a Ramsey microwave cavity designed to minimize the DCP frequency shifts. We present the evaluation of the contributing azimuthal components of the DCP shifts of NRC-FCs2.
