Abstract:
The fluxes of the nuclear component of the galactic cosmic radiation are discussed in terms of energy spectra for the different elements. Influences of shielding by the earth's magnetic field on these spectra are described. Then energy spectra behind absorbing matter are calculated considering energy loss and fragmentation. Based on these energy spectra LET-spectra are calculated. The form of the LET-spectra and their dependence on the composition of the shielding material are discussed. For LET-spectra measured by different detectors the restricted energy losses are converted to LETinfinity. in water. After this it is possible to compare the results of different experiments with each other and with calculated LET-spectra.
