Abstract :
A noise thermometer consisting of a nonhysteretic resistive SQUID has been used for unusually precise measurements of the low frequency Josephson linewidth of a heavily shunted point-contact. The results agree with theories appropriate for weak links, and support the contention that the pair fluctuation noise calculated for tunnel junctions is not present in point-contacts.
