Abstract
We have demonstrated the operation of a 12-channel
Beyer-style SQUID-based time domain multiplexer. It was
manufactured using a fabrication process that is
cross-compatible between VTT and IPHT-Jena. The
multiplexer consists of twelve 12-SQUID series arrays,
each shunted by a Zappe-style interferometer array acting
as a flux-controlled superconducting/normal conducting
switch. By keeping all switches but one in the
superconducting state, it is possible to select one
active readout channel at a time. A flux feedback coil
common to all SQUID arrays allows realization of a
flux-locked loop. We present characteristics of the
multiplexer and measurement data from experiments with a
25-pixel X-ray calorimeter array operated at T <100 mK
