| Примечания: | Title screen The use of quasiparticle diffusion in a superconducting film has the potential to allow an increase in the size of a cryogenic detector without proportional loss of energy resolution. The quasiparticle lifetime and the diffusion constant are critical parameters which have limited this development. Using W superconducting phase transition thermometers as the sensors and a W/Al bilayer as the diffusion film, we have measured quasiparticle diffusion over a distance of 2mm and deduced a diffusion constant of D = 2.5x10‾4m2/s and a quasiparticle lifetime of т = 9.0 ms , which is, to our knowledge, by far the longest ever observed. With Ir/Au thermometers and an Ir/Au/Al diffusion film we found D = 4.6x10‾3m2/s and т = 0.43 ms with diffusion over 4mm, the longest distance observed to date Режим доступа: по договору с организацией-держателем ресурса |
