Is anyone else attending PTTI 2018 this year in Reston, VA?
https://www.ion.org/ptti/
Perhaps people would be interested in a meet-up, I am here with my
university for a presentation but I am sure I can get away for a bit.

They did respond back and I am limited to 1. Wanted 2 but such is life. :-)
Will order most likely Monday.

Still, there are always a number of talks of more general interest to us time

Hi
I went through a similar process quite a while ago. The dimensions of the
actual fountain can be quite small. One could make one the size of a shoe box
and still have it perform quite well.

OK now that I am setting out to build one. Would the challenge for a
amateur be that the components you build with are basically dirty. Some how
on the copper pipe it would need to be clean and then brazed I might guess.
All of that makes for a dirty element.

A few kilometers of optical fiber should do the trick. Servo the fiber
temperature to keep things locked up.

- USNO rubidium fountains
While many national labs have developed cesium fountains (for
accuracy), USNO has been gradually building rubidium fountain clocks
(for stability) and 4 of them are now fully operational.
I just returned from PTTI (Precise Time and Time Interval), the annual
conference hosted by USNO, NASA, JPL, etc. Those of you unfamiliar with PTTI
can read more (http://pttimeeting.org/). Many of you know this site by the
fantastic collection of 40 years of archived (and free) technical papers
Hi Tom,
there are two that sound very interesting: the M12/uBlox one and the
Time-Nuts one :)
Do you have any other info, or could you give us a 1 minute overview of
what was shown please?
I also heard that there were scheduled to be more CSAC type papers, but
they did not get DARPA
The PTTI 2007 website has been updated with the Call for Papers. The link

Hi everybody,
Sometimes I find references to PTTI proceedings. Where can I find
these documents?
I had a look at the PTTI website http://tycho.usno.navy.mil/ptti.html
but I didn't find some of them!
Thanks again for helping me.
Bye. Michelangelo.
