Cosmic Ray Energetics and Mass ou CREAM es … Cosmic Ray Energetics and Mass ou CREAM est une expérience de physique dont l'objectif est de mesurer le spectre énergétique du rayonnement cosmique dont le spectre va de 1012 à 1015 eV. L'objectif scientifique est de déterminer l'origine et la nature du rayonnement cosmique en analysant plus particulièrement le changement d'indice spectral (ΔN/ΔE) qui se produit dans cette gamme d'énergie. L'expérience financée par la NASA est placée sous la responsabilité scientifique de l'Université du Maryland associée à plusieurs instituts de recherche et universités américaines et internationales. L'instrument de plus d'une tonne est constitué de plusieurs détecteurs de particules qui déterminent l'énergie et la charge électrique des particules incidentes. L'expérience a volé durant 161 jours sous un ballon stratosphérique dans le cadre de 6 campagnes distinctes qui se sont déroulées au-dessus de l'Antarctique entre 2004 et 2010. Une version légèrement modifiée est placée en orbite en aout 2017 et amarrée à l'extérieur de la Station spatiale internationale pour une mission de 3 ans. internationale pour une mission de 3 ans.
, Cosmic Ray Energetics and Mass (CREAM) is … Cosmic Ray Energetics and Mass (CREAM) is an experiment to determine the composition of cosmic rays up to the 1015 eV (also known as the "knee prospect") in the cosmic ray spectrum. It has been hypothesized that the knee prospect of the cosmic ray spectrum can be explained by the theoretical maximum energy that a supernova can accelerate particles to according to Fermi acceleration. The measurements are accomplished using a timing-based charge detector and transition radiation detector sent to an altitude of at least 34 km (21 mi) with aid of a high-altitude balloon. After launching from McMurdo Station in Antarctica, the balloon will stay aloft for 60–100 days gathering data on charges and energies of the unimpeded cosmic rays that strike the detectors.ded cosmic rays that strike the detectors.
