Experiments on scintillator-based detection of negative daemons, DArk Electric Matter Objects, representing Planckian supermassive ( ∼2⋅10 -5 g) particles, whose population has been detected in March 2000 to populate near-Earth, almost circular, heliocentric orbits (NEACHOs), are being continued. The NEACHO objects hit the Earth with a velocity ∼10-15 km/s. The results of these and new experiments (April through June 2001) are now processed taking into account the difference in scintillation signal shape depending on the magnitude and sign of the velocity of the daemons crossing our detector, which was purposefully made asymmetric with respect to the up/down direction of flight. The data accumulated during the time of the experiment and processed in this way reveal also the presence of (1) a high-velocity (~35-50 km/s) daemon population whose objects can be related to a population in the Galactic disk and/or that in strongly elongated, Earthcrossing heliocentric orbits (SEECHOs), as well as (2) a low-velocity ( ∼3-10 km/s) population in geocentric Earth-surface-crossing orbits (GESCOs), whose objects traverse repeatedly the Earth to suffer a decrease in velocity by ∼30-40% in a month in the process.An evolutionary relation between all these three (four?) populations is discussed. Assumptions concerning their manifestations in further observations are put forward.An analysis of possible interaction processes of daemons, which may have different velocities and directions of motion, with the detector components [ZnS(Ag) scintillator layers, 0.3-mm thick tinned-iron sheets etc.] on the atomic (emission of Auger electrons) and nuclear (nucleon evaporation from a nucleus excited in the capture and, subsequently, the decay of its protons) levels has permitted estimation of some characteristic times. In particular, the decay time of a daemon-containing proton was found to be ∼1 µs.

Energy of ions (recoil nuclei) channeled along definite directions in crystals is transferred to the lattice electrons mainly. In NaI(Tl)-type scintillators, this leads to increasing the light yield from ∼10% to ∼100% when compared with the yield for electrons of the same energy. Taking into account this effect at processing data of DAMA/NaI experiments in Gran Sasso, which had demonstrated the year modulation of number of signals in a range of 2-6 keV of electron equivalent, reveals that DAMA/NaI results could be caused by ∼6×10 −7 cm −2 s −1 flux of daemons (Dark Electric Matter Objects -presumably Planckian relic particles) falling out from strongly elongated heliocentric orbits with velocities of 30-50 km/s. The flux value and the 2-6 keV signal intensity agree rather well with values emerging from our former estimates and interpretations of ground-level and underground measurements.

Attention is drawn to a principal difference between the transfer of a horizontal magnetic field by turbulence and by three-dimensional cell convection.If the motion of the conducting medium in the cells is such that the heated material ascends at the centre while descending along the sides of the cells, then the magnetic tubes of force will be carried downwards by peripheral flows. Discrete ascending flows separated from one another by descending material carry only closed magnetic field loops. Such loops do not transfer net magnetic flux. As a result, the magnetic flux becomes blocked at the base of the convective layer.

Detection of daemons in low-background conditions in September 2005 andMarch 2006 has provided supportive evidence for the expected to occur at that times maxima in the flux of daemons with V ≈ 10-15 km s -1 , which hit the Earth from near-Earth, almost circular heliocentric orbits (NEACHOs). The ability of some FEU-167-1 PM tubes with a thicker inner Al coating to detect directly (without a scintillator) daemon passage through them has also been demonstrated, an effect increasing 100-fold the detector efficiency. As a result, the daemon flux recorded at the maxima was increased from ~10 -9 to ~10 -7 cm -2 s -1 . At the maxima, two phases in the observed flux can be discriminated. The first of them is associated with objects which catch up with the Earth in moving in outer NEACHOs and cross it. The intensity and direction of the flux during this phase which lasts about two weeks depend on the time of day and latitude of observations (therefore, synchronous measurements in the Northern and Southern Earth's hemispheres are desirable). In the second phase, where the flux consists primarily of few objects captured into geocentric, Earth-surface-crossing orbits (GESCOs) during the first phase, the daytime and latitude dependence becomes less pronounced. The experiments suggest an explanation for the fairly poor reproducibility of our earlier ground-level measurements (subtle differences in PMT design, varying radon background etc.). All the experimental results thus obtained either support the conclusions following from the daemon paradigm or find a simple interpretation within it.
