“…Low-temperature microcalorimeters such as semiconductor thermistors [1], superconducting transition edge sensors (TESs) [2,3], magnetic penetration depth thermometers [4] and metallic magnetic calorimeters (MMCs) [4][5][6] are presently strongly advancing the state-of-the-art in single particle detection for various kinds of applications including atomic and nuclear physics [7][8][9][10][11], direct neutrino mass determination [12,13], searches for neutrinoless double beta decay [14,15], nuclear safeguards [16,17], Q-spectroscopy [18,19], radiation metrology [20][21][22][23], mass spectrometry [24], and material analysis [25,26]. In general, a microcalorimeter consists of an absorber for the particles to be detected that is in tight thermal contact with a highly sensitive thermometer monitoring the temperature change of the detector upon the absorption of an energetic particle.…”

We report on the design, fabrication and characterization of a 64 pixel metallic magnetic calorimeter array that is read out by an integrated, on-chip microwave SQUID multiplexer. Based on the results of our comprehensive device characterization we refined the state-of-the-art multiplexer model which assumes each associated non-hysteretic rf-SQUID to purely behave as a flux-dependent inductor. In particular, we include the capacitance and the subgap resistance of the Josephson junction as well as screening effects and parasitic mutual couplings between different coils that show up only when a superconducting flux transformer is attached to the SQUID input. Thanks to these modifications, we are able to explain the occurrence of a magnetic flux dependence of the internal quality factor of the microwave resonators as well as to accurately calculate the characteristic multiplexer parameters. When combining the refined multiplexer model with the thermodynamical description of a metallic magnetic calorimeter, we find a reasonable agreement between our measurements and predictions.

“…These arrays are routinely used in a variety of applications and often appear to be a key technology for measurements that require high-resolution and wide-band energy-resolving detectors. MMCs have already been proven to be eminently suited detectors for various applications such as high resolution X-ray spectroscopy [1], nuclear forensics [2], radiation metrology [3] or direct neutrino mass investigation.…”

“…An in-house development is also promising because the use of electronics is not limited to ECHo, but can also be used for other MMCbased experiments. This is particularly interesting because at the same time MMCs are a key technology for a large number of experiments and various domains including high resolution X-ray spectroscopy [1], nuclear forensics [2], radiation metrology [3] or direct neutrino mass investigation. The remainder of this paper is structured as follows: Section II will introduce the ECHo experiment, the MMC detector technology and the innovative frequency division multiplexing readout scheme.…”

Metallic magnetic calorimeters (MMCs) are cryogenic detectors that offer an excellent energy resolution, a signal rise time of <100 ns, a high dynamic range and almost optimal linearity. MMCs are of high interest for many experiments. One of them, the ECHo experiment, requires the utilization of large MMC detector arrays. The readout of such MMC arrays is a challenging task, which can be tackled using softwaredefined radios (SDRs). Though SDR is a well-known approach in communications engineering, a dedicated implementation for frequency division multiplexed readout of MMCs is new and one of the technological key elements of the ECHo project. ECHo will be the first experiment to use microwave SQUID multiplexed MMC detectors and therefore pioneering the hardware, firmware and software development in this domain. This paper presents the detailed concepts and current status of the development.

MMCs have already proven to be eminently suited detectors for various applications such as high resolution X-ray spectroscopy [2], nuclear forensics [3], radiation metrology [4] or direct neutrino mass investigation. In particular, the "Electron capture in Holmium-163 experiment" (ECHo) [5,6], which aims to investigate the electron neutrino mass in the sub-eV/c 2 range by performing a calorimetric measurement of the 163 Ho electron capture spectrum, requires the acquisition of a high-resolution and high-statistics spectrum with up to 10 14 decays.…”

Metallic magnetic calorimeters (MMCs) are cryogenic detectors that offer an excellent energy resolution, a signal rise time of below 100 ns, a high dynamic range and almost optimal linearity. MMCs are of high interest for many experiments, such as dark matter detection or direct neutrino mass investigations. Since larger detector arrays are read out at GHz-Frequencies, and each single pixel offers a fast rise time, a complex analog and digital readout system is required. This contribution will give an introduction to MMC technology in combination with the implemented readout electronics and the current status of the present readout architecture.
