Query: Characterization of low temperature metallic magnetic calorimeters
  having gold absorbers with implanted $^{163}$Ho ions   For the first time we have investigated the behavior of fully
micro-fabricated low temperature metallic magnetic calorimeters (MMCs) after
undergoing an ion-implantation process. This experiment had the aim to show the
possibility to perform a high precision calorimetric measurement of the energy
spectrum following the electron capture of $^{163}$Ho using MMCs having the
radioactive $^{163}$Ho ions implanted in the absorber. The implantation of
$^{163}$Ho ions was performed at ISOLDE-CERN. The performance of a detector
that underwent an ion-implantation process is compared to the one of a detector
without implanted ions. The results show that the implantation dose of ions
used in this experiment does not compromise the properties of the detector. In
addition an optimized detector design for future $^{163}$Ho experiments is
presented.
