Abstract:
Magnetic microcalorimeters (MMCs) have become one of the low-temperature detector technologies operating at mK temperatures. MMCs have been developed based on the noble properties of superconducting circuits to measure magnetic signals caused by energy absorption in a detector. As with other low-temperature detectors, MMCs provide a phonon detection channel with an extreme energy sensitivity. In addition, the detector technology is particularly useful for an experiment when the timing resolution becomes a crucial parameter. This talk introduces the principles and advantages of MMC applications in astroparticle physics. In particular, I will cover the status of an experimental search for neutrinoless double beta decay, the Advanced Mo-based Rare process Experiment (AMoRE), and the LiF Experiment (LiFE) for a keV-scale sterile neutrino search.
