Description
The ECHo collaboration aims at measuring the electron neutrino mass
by recording the spectrum following electron capture of $^{163}$Ho using
metallic magnetic calorimeters (MMCs).The radioisotope $^{163}$Ho
is produced from enriched $^{162}$Er in the ILL high flux nuclear reactor,
chemically purified and mass separated and
is fully embedded into the 180x180 µm$^{2}$ Au-absorber of the
ECHo MMCs. Resonance ionization mass separation guarantees
elemental and isotopic selectivity for ultra-pure $^{163}$Ho ion implantation
with a sub millimeter beam spot size. On-line in-situ deposition of Au using pulsed laser
deposition (PLD) ensures homogeneous $^{163}$Ho/Au layer formation in
the implantation area. To verify the purity of the ECHo source material
from production up to implantation and data taking a varity of
different analytical techniques is applied, including 𝛾-ray spectrometry,
NAA, ICP-MS and RIMS.
