Well, now that I'm back from Boulder, I should post some comments on the shindig.
Seminar http://tf.nist.gov/seminars/TFSeminar2012/Seminar_37.html This was definitely a professional level seminar, as evidenced by the cost and the topics. I've been lurking on the Time Nuts for a while, as I have some work related interests in precision frequency and low phase noise, but in no way can be considered an expert in time and frequency metrology. The event was at the NIST Boulder facility, and was well run. Most of the speakers were actively working on the topics that they presented, so the technical expertise was there. The day's were long, as you could tell. One of the highlights for me was the discussion on TheoH, which seems to be a measurement to use instead of the Allan deviation. It seems to provide information further out in time for the same record lengths, and so I'll have to take another look at some data I have with TheoH instead of the Allan deviation. One of the other interesting things was the presentation on the Al+ optical clock. They claimed to be able to jack up the optical bench that this clock is on, and measure the frequency offset caused by the change in height. They're getting time accuracies down in the 10e-18 level! I"m waiting for a Time nut to start looking at Optical comb techniques. Who's going to be first? Had dinner Tuesday night with the other local Time Nuts, as well as John and Magnus. That was entertaining, with Tom and Skip providing some entertaining/depressing stories of the surplus marketplace. John had a Timepod there, which seems like a pretty useful box for digital measurements.
