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....

Subject: [time-nuts] new Al atomic clock publication
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.
