Improved accuracy of the NPL-CsF2 primary frequency standard: evaluation of distributed cavity phase and microwave lensing frequency shifts
NPL-CsF2 primary frequency standard cavity phase microwave lensing frequency shifts
2011/8/17
Abstract: We evaluate the distributed cavity phase and microwave lensing frequency shifts, which were the two largest sources of uncertainty for the NPL-CsF2 cesium fountain clock. We report measureme...
