Abstract

We present our first results obtained using new high-speed SQUID systems for the readout of normal conductor/insulator/ superconductor (NIS) and superconductor/insulator/superconductor (SIS) tunnel junctions. With an NIS device measured with a HYPRES SQUID we have achieved an energy resolution of 100 eV (FWHM) for 5.89 keV X-rays and an electronic noise of 40 eV at an operating temperature of 80 mK. With an SIS sensor at 200 mK and the same readout we have achieved an energy resolution of 29 eV (FWHM) at 5.89 keV and an electronic noise of 10 eV.
