The 66-channel SQUID readout system for CRESST II

The upgrade of the CRESST experiment to a 10 kg target of phonon/light detectors necessitates the installation of 66 readout channels in the CRESST cryostat. We report on the status of this upgrade and discuss the issues related to the installation of the correspondingly high number of SQUIDs and wires in an ultra-low temperature environment.
