Azcárate Física, Astronomía y Matemáticas BALLOONS INSTRUMENTATION: DETECTORS INTERSTELLAR MEDIUM: COSMIC RAYS An experiment performed with a balloon-borne large plastic scintillator isdescribed. The detector system was transported by a stratospheric balloon, thatwas launched from Reconquista, Provincia of Santa Fe, Argentina, on February 24,1992. The geomagnetic cut-off of the site is 11.5 GV. The energy loss spectra ofboth the atmospheric gamma-radiation (for E 4:15 MeV) and the charged component of the secondary cosmic radiation were alternatively measured at differentaltitudes, during the ascent of the balloon, and at ceiling altitude. The atmosphericgamma-ray spectrum was analyzed in an earlier paper (Azcárate 2000). The shapeof the energy loss spectrum due to charged radiation can be explained, at leastqualitatively, by the computation of the response of the detector to this type ofradiation.It is argued that, at ceiling altitude, the observed feature in the spectrum isdue mainly to relativistic muons inciding horizontally on the detector. The growthcurve for the counting rate below the peak and the intensity of relativistic U mesonsare also obtained. 2001 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57137204 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.37 |
