Importance of Atmospheric Model in Shower Reconstruc- tion
نویسندگان
چکیده
The influence of an atmospheric model on shower reconstruction is studied. In the fluorescence detection technique, one of the key measurements is the depth of shower maximum in the atmosphere,Xmax. The altitude corresponding toXmax depends considerably on distributions of atmospheric pressure and temperature, used in the shower reconstruction. In this paper, measured atmospheric profiles at different geographic locations are compared to the US Standard Atmosphere model. A study of the atmospheric effect in shower reconstruction as a function of shower inclination and energy is done. Seasonal variations of atmosphere are shown to affect considerably the Xmax determination.

Background: Acute pain is common after arthroscopic surgeries and it is one of the most important causes of patient dissatisfaction, admission time and increased morbidity . Gabapentin with anti-hyperalgesic effects can play a critical role in pre-emptive analgesia methods. The aim of this study was to assess the efficacy of gabapentin in pain management after surgery and the rate of drug consu...
متن کاملVariation of atmospheric depth profile on different time scales
The vertical profile of atmospheric depth is an important element in extensive air shower studies. The depth of shower maximum is one of the most important characteristics of the shower. In the fluorescence technique of shower detection, the geometrical reconstruction provides the altitude of shower maximum, so that an accurate profile of atmospheric depth is needed to convert this altitude to ...
متن کاملThe FLUKA atmospheric neutrino flux calculation
The 3–dimensional (3–D) calculation of the atmospheric neutrino flux by means of the FLUKA Monte Carlo model is here described in all details, starting from the latest data on primary cosmic ray spectra. The importance of a 3–D calculation and of its consequences have been already debated in a previous paper. Here instead the focus is on the absolute flux. We stress the relevant aspects of the ...
متن کاملAn Evolutionary Approach to CT Image Reconstruction *
There is presented an evolutionary approach to the problem of CT image reconstruc tion: a genetic algorithm is used to reconstruct a CT image from a limited number of projection data, where conventional methods (e.g. Algebraic Reconstruction Techniques ART) solution tends to be unsatisfactory. We use traditional as well as adapted genetic operators in our evolutionary ap proach to the CT image ...
متن کاملImpact of Varying Atmospheric Profiles on Extensive Air Shower Observation: - Atmospheric Density and Primary Mass Reconstruction -
The longitudinal profile of extensive air showers is sensitive to the energy and type/mass of the primary particle. One of its characteristics, the atmospheric depth of shower maximum, is often used to reconstruct the elemental composition of primary cosmic rays. In this article, the impact of the atmospheric density profile on the reconstruction of the depth of maximum, as observed in fluoresc...
