Cosmic Ray Spectral Deformation Caused by Energy Determination Errors
Per Carlson, Conny Wannemark
Using simulation methods, distortion effects on energy spectra caused by errors in the energy determination have been investigated. For cosmic ray proton spectra, falling steeply w…
PoGOLite - A High Sensitivity Balloon-Borne Soft Gamma-ray Polarimeter
Tuneyoshi Kamae, Viktor Andersson, Makoto Arimoto +36
We describe a new balloon-borne instrument (PoGOLite) capable of detecting 10% polarisation from 200mCrab point-like sources between 25 and 80keV in one 6 hour flight. Polarisation…
Fluctuation studies and energy reconstruction in a segmented calorimeter
Sara Bergenius Gavler, Per Carlson, Jan Conrad
In order to better understand energy estimation of electromagnetic showers in segmented calorimeters, detailed Geant4 simulation studies of electromagnetic showers in the energy ra…
Nationalism and internationalism in science: the case of the discovery of cosmic rays
Per Carlson, Alessandro De Angelis
The discovery of cosmic rays, a milestone in science, comprised scientists in Europe and the US and took place during a period characterised by nationalism and lack of communicatio…
