Cryogenic Sapphire Oscillator using a low-vibration design pulse-tube cryocooler: First results
John G. Hartnett, Nitin R. Nand, Chao Wang +1
A Cryogenic Sapphire Oscillator has been implemented at 11.2 GHz using a low-vibration design pulse-tube cryocooler. Compared with a state-of-the-art liquid helium cooled CSO in th…

Ultra-low vibration pulse-tube cryocooler stabilized cryogenic sapphire oscillator with 10^-16 fractional frequency stability
John G. Hartnett, Nitin R. Nand
A low maintenance long-term operational cryogenic sapphire oscillator has been implemented at 11.2 GHz using an ultra-low-vibration cryostat and pulse-tube cryocooler. It is curren…
