  The "Troitsk anomaly" is a strange bump at the end of the tritium beta
spectrum observed in electron antineutrino mass measurements. It reveals a
half-year variation. The nature of the anomaly can be accounted for by
interaction of negative DArk Electric Matter Objects - daemons detected by us
with the Nb-containing superconducting coils of the gaseous tritium source of
the setup. In crossing the system, the daemons, whose flux varies with a
half-year period, drag away Nb-containing clusters and excite their nuclei and
electronic shells to produce emission of five Auger electron lines within E =
18566-18572 eV. This yields an estimate for the daemon flux ~10-7-10-6 cm-2s-1.
It is shown that in the KATRIN system (KArlsruhe TRItium Neutrino experiment)
presently under construction the ratio of the daemon-stimulated Auger bump
signal to the useful beta-signal should be larger than that in the Troitsk
experiment. The potential of using slightly modified systems at Troitsk and
Karlsruhe to study the daemons is pointed out.
