Cryocooled Sapphire Oscillator at N.I.C.T. Tokyo Japan

In 2006 I built and delivered a liquid-helium-cooled cryogenic sapphire oscillator to NICT in Tokyo. In August 2014  I upgraded that  sapphire oscillator to use a cryocooler, hence saving them a lot of money as the cryocooler uses very little helium. The earlier version consumed 7 litres per day @ $50 a litre. It’s expensive to run.
