[time-nuts] new Al atomic clock publication

[Bob Camp]

Hi

All that work and the biggest chunk of uncertainty contains "fluctuations
caused by periodic line noise (50 to 60 Hz)".

I guess even NIST can't afford good shielding....

No discussion on the new Al based atomic clock paper from NIST?

http://arxiv.org/PS_cache/arxiv/pdf/0911/0911.4527v2.pdf

"Here we describe an Al+ ion clock with an inaccuracy of 8.6×10−18."

Doesn't get more nutty than that.
