Observation of the March maximum in the daemon flux from near-Earth orbits in the year 2005: new efforts and new effects
Abstract:The experiments in 2005 aimed at detection of low-velocity (about 10–15 km s − 1 ) daemons falling on to the Earth's surface from near-Earth, almost circular heliocentric orbits have corroborated once more the existence of the March maximum in their flux by raising the confidence level to 99.99%. In addition, these experiments permitted us to identify several FEU-167-1-type photomultiplier tubes, with an inner aluminium coating a few times thicker, which appear to be capable of detecting, without any scintillator, the crossing of negatively charged daemons. As a result, the detection efficiency increases tens of times, thus raising the measured level of the March daemon flux to f ⊕ ≥ 0.5 × 10 − 7 cm − 2 s − 1 .
