Compact laser system for a laser-cooled ytterbium ion microwave frequency standard
S. Mulholland, H. A. Klein, G. P. Barwood +6
The development of a transportable microwave frequency standard based on the ground-state transition of at ~12.6 GHz requires a compact laser system for coo…
Laser-cooled ytterbium ion frequency standard
S. Mulholland, H. A. Klein, G. P. Barwood +6
We report on the development of a trapped-ion, microwave frequency standard based on the 12.6 GHz hyperfine transition in laser-cooled ytterbium-171 ions. The entire system fits in…
A low maintenance Sr optical lattice clock
Ian R. Hill, Richard Hobson, William Bowden +4
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. C…
Fast shuttling of ions in a scalable Penning trap array
D. R. Crick, S. Donnellan, S. Ananthamurthy +2
We report on the design and testing of an array of Penning ion traps made from printed circuit board. The system enables fast shuttling of ions from one trapping zone to another, w…
