Description

Status report is given on the Yb optical lattice clocks developed at KRISS. KRISS-Yb1 is being operated regularly to contribute to International Atomic Time (TAI). KRISS-Yb2 was developed to reach the 10^-18 uncertainty level overcoming the BBR shift uncertainty of KRISS-Yb1. Preliminary uncertainty evaluation results of KRISS-Yb2 will be presented at the conference.
