Geomagnetic Field Eect over Azimuth Anisotropy of Cosmic Rays via Study of Primary Particles
Geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. Here we present the question: Is there any azimuth anisotropy flux in the upper level of the atmosphere due to the geomagnetic field over the entered cosmic-rays? The obtained answer is: yes. This investigation showed an agreeme...
متن کاملDetailed analysis of observed antiprotons in cosmic rays
In the present work, the origin of antiprotons observed in cosmic rays (above the atmosphere) is analyzed in details. We have considered the origin of the primaries, (which their interactions with the interstellar medium is one of the most important sources of antiprotons) is a supernova type II then used a diffusion model for their propagation. We have used the latest parameterization for anti...
متن کاملTime Delays in Cosmic Ray Propagation
Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...
متن کاملA study on the lateral distribution of Cherenkov light in extensive air showers
The dependence of the lateral distribution of Cherenkov light in simulated extensive air showers to the energy and the mass of the primary cosmic rays has been studied. It has been shown that a previous claim about mass independent proportionality of shower energy to the total Cherenkov photon number is not valid in energies below EEAS ~ 1014 eV. We have found that the core distance of the so c...
متن کاملمشاهده سایه خورشید با تلسکوپ ردیاب پرتوهای کیهانی
A cosmic ray tracking telescope has been made for the measurement of cosmic rays from different directions, especially those received from the sun direction. Our observations by the telescope shows a noticeable deficiency in the detected number of cosmic rays entering the telescope when its axis was pointing to the sun compared to that entering the telescope with no sun in its field of view. Th...
متن کاملPhysical Investigation of Space, Dosimetry of Space Ionizing Ray Effect (Van Allen belts, Galactic Cosmic Rays and Solar particles) and Plotting Dose Map for Satellite Circular Missions
One of the main factors for satellite design is simulating of total ionizing dose due to space ionizing rays in devices used in space. By measurement of induced dose based on available data in different altitudes, expenses of designing, satellite weight and amount of needed fuel will be reduced. Optimum design of satellite for protecting satellite against ionizing radiation has considerable eff...
