4.1.3 Operation and Performance <strong>of</strong> dc-SQUIDs<br />
AS-Chap. 4 - 19<br />
• important parameters for practical applications <strong>of</strong> SQUIDs<br />
flux-to-voltage transfer coefficient (measure <strong>of</strong> sensitivity to flux):<br />
maximum at steepest point <strong>of</strong> hVi(F ext )<br />
flux to voltage transducer<br />
equivalent flux noise (measure <strong>of</strong> flux resolution)<br />
S V (f): power spectral density <strong>of</strong> voltage<br />
noise at fixed bias current<br />
noise energy (measure <strong>of</strong> energy resolution, good for comparison <strong>of</strong> different SQUID geometries)<br />
sets energy resolution<br />
should be as small as possible
