Abstract

This paper presents non-destructive dark current measurements of superconducting TESLA cavities for superconducting LINACs. The measurements were carried out in a highly disturbed accelerator environment using a low temperature superconducting d.c. SQUID based Cryogenic Current Comparator (CCC). The overall current sensitivity under these rough conditions was measured to be 0.2 nA/sqrt(Hz) which enables the detection of dark currents of 5 nA.
