First NuMI neutrinos announced

SPOTLIGHT | June 18, 2014

Scientists will detect a small fraction of neutrinos in the near detector at Fermilab, and the rest in a larger far detector in Minnesota. Throughout the trip, researchers will be looking for signals that the neutrinos are changing from one type to another.

Scientists from the NOvA collaboration, an experiment designed to study the strange properties of neutrinos, recently announced that the NOvA detector has identified its first NuMI neutrinos. The study, including 180 scientists and engineers from 28 institutions, hopes to uncover the elusive transition from muon neutrinos to electron neutrinos.

Originating from the first moments of the universe, unimaginably large numbers of neutrinos — a billion times more abundant than the particles that make up stars, planets, and people — are still present today. They have the curious ability to pass through an entire planet as if it were empty space.

To study neutrino behavior, the NOvA experiment uses two detectors: a 330 metric-ton near detector at Fermi National Accelerator Laboratory, located just outside of Chicago, Illinois, US, and a much larger 14 metric-kiloton far detector close to the Soudan Mine in Minnesota, US.

Much like a beam of light from a flashlight, a neutrino beam gradually spreads as it travels. The 1.8-meter NuMI beam begins at Fermilab and grows to several kilometers by the time it reaches the far detector in Minnesota. Detection of the first neutrinos means the near detector is responding as it should. Completion of the final construction of the near detector is expected later this summer.

Another case of delusion that

Another case of delusion that physicist made up about originate of the universe. The premature conclusion is based upon the data of neutrino registration deep underground (under ice) in Antarctica, where for about several years was registered some ten of cases: several high energy neutrinos and some ten cases relatively low energy neutrinos….. that are the facts! There is necessary a lot much years of confirming such cases to be sure from what directions come mainly these particles and to estimate the energy spectrum through more cases observing. So the experiment is far away from the conclusions. But some physicist instantly decided that this is evidence about “big bang” “young stars” and soon. And all these, if the physics nowadays can’t say anything about the essence of these mysterious particles called neutrino! Let me explain: According to USM www.kanevuniverse.com in the beginning when our space (universe) was started in the center of our galaxy, that started is with very first orbital system containing only two proto particles representing very first “hydrogen atom” from two almost equal proto particles with mass 1,8.10 rising to a 13 power times smaller than the mass of proton. In this moment with appearance of this very first orbital system appears the energy itself as well and this energy is almost equal to zero and the first real value appears together with the first difference between the masses of the two proto particles. And that difference appears because of the beginning of space expansion provoked by the added new masses (proto particles), which disturb the inertial balance of this very first orbital system (see part I USM). That was our universe in this very first moment. Then begin to expands the macro cosmos and begin respectively to thickening the micro cosmos, which means that the nuclear proto particle in the beginning orbital system begin to weigh more quickly than the orbiting proto particle, because the first is on the center (more close to the micro cosmos). How it is seen the two particles during movement towards the periphery of our galaxy come to our position of observation where the central particle already has the mass of proton and the orbiting one possesses mass of electron, so in our position of observation the proton has resonance radius equal to the size of proton (see USM) and the electron has resonance radius equal to the size of atom. But what has happened with expansion of the macro cosmos (our galaxy) looked at our position of observation? The resonance radius of the first proto particle in the very first orbital system (“hydrogen atom”) in fact is the size of this very first orbital system, so during the expansion of the macro cosmos this resonance radius begin to expands which means that it represents more and more lightering of the proto particle mass and when this process come to our point of observation this particle already has the mass of neutrino, see page 128 to 138 USM www.kanevuniverse.com In the formulae 125 and 126 is given the masses spectrum of electronic neutrino and the masses spectrum of muon neutrino and the explanation for that. So the high energy spectrum neutrinos actually comes from the smaller resonance radius in any galaxy (more closer belts of centripetal accelerations) and lower spectrum respectively comes from the periphery belts of centripetal accelerations again in any galaxy. So obviously observed here neutrinos has nothing to do with “big bang” and so for absurdity! G.Kanev
