Description
We are developing a highly compact and high-performance vapor-cell atomic clock operating in time-domain Ramsey scheme [1]. Here, we present an analysis of the dominant contributions to the clock instability at the level of 10$^{-14}$, on long-term timescales up to one day. Main limitations arise from light-shift effects, the barometric effect (i.e. the sensitivity to environmental pressure variations), and microwave power-shift effects. The full detailed instability budget will be discussed at the conference. The clock reaches a measured instability of <2x10$^{-14}$ at one day.
