Cosmic rays are high-energy protons and atomic nuclei which move through space at nearly the speed of originate from the sun, from outside of the solar system, or even from distant galaxies. Upon impact with the Earth's atmosphere, cosmic rays can produce showers of secondary particles that sometimes reach the from the Fermi Space Telescope () have been interpreted.

Abstract. With experimental results of AMS on the spectra of cosmic ray (CR) e- e +, e-+ e + and positron fraction, as well as new measurements of CR e-+ e + flux by HESS, one can better understand the CR lepton (e-and e +) spectra and the puzzling electron-positron excess above ∼10 this article, spectra of CR e-and e + are fitted with a physically motivated simple model, and Author: Zhao-Dong Shi, Zhao-Dong Shi, Siming Liu, Siming Liu.

In this Letter, we present a new measurement of the cosmic ray positron fraction up to energies of 30 GeV with the AMS detector.

Positrons are identified by conversion of bremsstrahlung photons, which yields an overall proton rejection on the order of 10 6. This approach allows to extend the energy range accessible to the experiment far beyond its design limits and to fully exhaust the detector's by: The best measurement of the cosmic ray positron flux available today was performed by the HEAT balloon experiment Cosmic ray positron research and silicon track detector development book than 10 years ago.

The CREAM C–Fe data are consistent with the HEAO-3 (Engelmann et al. ) and Cosmic Ray Nuclei Detector (CRN; Müller et al. ) data at low energies, and the TRACER (Ave et al.

) data where they overlap. We note that there is only one TRACER data point between ~10 GeV/nucleon and ~ GeV/nucleon, where we observe spectral shape by:   I show my experimental scintillation cosmic ray detector which detects cosmic rays (muons at sea level). I also outline my plans for doing a permeant (1.

Up on the roof of the Institute of Physics building is a device for detecting another type of radiation that is invisible to the eye: cosmic rays. The detector was built by students from a local.

PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) was a cosmic ray research module attached to an Earth orbiting satellite. PAMELA was launched on 15 June and was the first satellite-based experiment dedicated to the detection of cosmic rays, with a particular focus on their antimatter component, in the form of positrons and antiprotons.

Other radiation detectors can be used like Geiger Counters, Spark Chambers, Resistive Plate Chambers and materials called Scintillators which give off light when an ionizing particle passes through them. The problem using a radiation detector for a cosmic ray observation is that there is larger amounts of terrestrial radiation as much 73% of background radiation is due to the natural decay of.

Positron-Emission Tomography Detectors There is nothing that inspires GE Research scientists and engineers more than transforming technologies that improve or help save people’s lives. Our detector technologists are not an exception; for over 15 years they have been at the center of the Healthcare industry’s transformation of the positron.

cosmic ray detectors. But how. Step 1: Construction To construct a cosmic ray detector, first you need a design. We have several designs from which to choose. Each has strengths and weaknesses and each is better suited for some kinds of experiments than the others.

Bonvicini, anomalous light flashes perceived by astronauts in orbit by employing silicon detectors placed around the astronaut’s head and it was conducted on-board These features allow to extend their use also to cosmic-ray experiments on satellites.

The Pierre Auger Observatory is studying ultra-high energy cosmic rays, the most energetic and rarest of particles in the universe. When these particles strike the Earth's atmosphere, they produce extensive air showers made of billions of secondary particles.

While much progress has been made in nearly a century of research in understanding cosmic rays with low to moderate energies, those with. COSMIC RA YS This recommended program includes two major new programs: (1) development of a Superconducting Magnetic Spectrometer Facility for the Space Station, which will permit "a series of cosmic-ray experi- ments" as suggested by the second Astronomy Survey Committee recommendation above, and (2) a Cosmic-Ray Composition Explorer that.

The high-energy cosmic ray passes in a near-straight line through the detector, and the vertex-finding algorithm attempts to identify it as a two-track annihilation with an unphysical vertex. The apparatus is a system of electronic particle detectors optimized for the study high energy end of the cosmic-ray positron spectrum.

Silicon Lithium X-Ray Detectors are the heart of solid state x-ray spectroscopy systems. These detectors, which are p-i-n devices formed by lithium compensation or drifting of p-type silicon, are the result of some of the most carefully controlled manufacturing processes in existence.

Cosmic rays were discovered in by an Austrian physicist, Victor Hess, who flew simple instruments aboard balloons and showed that high-speed particles arrive at Earth from space (Figure ).

The term “cosmic ray” is misleading, implying it might be like a ray of light, but we are stuck with the name. Make: Projects 1+2+3: Cosmic Ray Detector.
