Abstract
We report our progress in achieving precise frequency measurements by integ rating high-Q superconducting-cavity-stabilized oscillators (SCSO) with hig h-resolution thermometry and phase-locked-loop (PLL) techniques. The releva nt effects that influence the ultimate frequency stability of SCSO (10(-17) -10(-18)) are described, and applications of this technique to precise meas urements of the liquid helium critical phenomena are discussed.
