[time-nuts] Sapphire oscillators

[timeok]

   Hi,
   this project is published in the Enrico Rubiola site sice the 2008:
   http://rubiola.org/pdf-articles/archives/2009-arxiv-0909.3971v1-Elisa.pdf
   Very interesting for short and medium term stability.
   Cryogenic multistage expensive cooler is necessary.
   regards
   Luciano
