A low maintenance Sr optical lattice clock

I R Hill, Richard Hobson, W Bowden +4 more

We describe the Sr optical lattice clock apparatus at NPL with particular emphasis on techniques used to increase reliability and minimise the human requirement in its operation. Central to this is a clock-referenced transfer cavity scheme for the stabilisation of cooling and trapping lasers. We highlight several measures to increase the reliability of the clock with a view towards the realisation of an optical time-scale. The clock contributed 502 hours of data over a 25 day period (84% uptime) in a recent measurement campaign with several uninterrupted periods of more than 48 hours. An instability of 2 x 10 -17 was reached after 10 5 s of averaging in an interleaved self-comparison of the clock.

We present a comprehensive study of the frequency shifts associated with the lattice potential in Sr lattice clocks. By comparing two such clocks with a frequency stability better than 5.10-17after one hour of averaging time, and varying the lattice depth up to U0= 900 Erwith Erbeing the recoil energy, we evaluate lattice related shifts with an unprecedented accuracy.
