M. DROBYSHEVSKI and M. E. DROBYSHEVSKI Ioffe Physico-Technical Institute, Russian Academy of Sciences St.Petersburg, 194021 Russia; E-mail: emdrob@mail.ioffe.ru Experiments with thin ZnS(Ag) scintillators provide evidence with C.L. 99.99% for the existence of DArk Electric Matter Objects - daemons (presum- ably negatively charged Planckian particles with M ～ 10?5 g) captured from the Galactic disk into near-Earth, almost circular heliocentric orbits (NEA- CHOs). Their flux at V ≈ 10-15 km/s was found to be as high as f⊕ 10?7 cm?2s?1 and vary with P = 0.5 y, with maxima in March and September. A daemon flux f⊕ ～ 10?7-10?6 cm?2s?1 is capable of accounting for the Troitsk anomaly in the 3T β-spectrum and suggests its more pronounced manifestation in future KATRIN experiment. In view of the channeling effect on iodine recoil nuclei in the NaI(Tl) crystal, the DAMA/NaI experiment is also apparently detecting a flux of daemons, f⊕ ～ 6×10?7 cm?2s?1, but in this case of those falling with V = 30-50 km/s from strongly elongated, Earth-crossing heliocen- tric orbits (SEECHOs) oriented in the antapex direction, as a result of which the number of events detected in the 2-6-keV interval varies with P = 1 y. 1. Planckian DM objects and possibility of their detection Our Universe started from Planckian scales, and it appears only reasonable to assume that the larger part of its mass, Dark Matter (DM), remains confined in Planckian objects, elementary black holes whose gravitational radius cannot be smaller than their Compton wavelength. Such objects with M ～ 10?5 g and rg ～ 10 ?33 cm can carry an electric charge of up to Ze ≈ G1/2M ≈ 10e. While the properties of similar DArk Electric Matter Objects, daem
