High performance temperature controller: application to the excess noise measurements of YBCO thermometers in the transition region

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/21454Dedicated read-out electronics was developed for low impedance resistive thermometers. Using this high performance temperature controller, the temperature dependence of the excess noise of a YBa2Cu307-d (YBCO) sample in the superconducting transition was monitored as a function of the current bias. The noise could reach 3.10-8 K Hz-1/2 at 1 Hz, 5 mA bias and 90 K.4 pages, contribution to 17th International Conference on Noise and Fluctuations (ICNF17), Prague (August 2003)SuperconductivityHigh performance temperature controller: application to the excess noise measurements of YBCO thermometers in the transition regiontext
