Welcome to the Home Page of Cosmos
New mirror site
Cosmos (from v8.00)
is now compatible with the formal Fortran grammar:
i.e, can be compiled with GNU gfortan as well as
Intel ifort. etc
The essential difference from the older ones is in the
treatment of the "structure construct".
The conversion of "old to new" style was
the new Cosmos development team
For more details,
see a short manual
with some updated features in this version.
It is a versatile
Monte Carlo simulaiton code for propagatio of
cosmic rays in the atmosphere and near earth environment.
It can treate
low energy phenomena such as atmospheric
neutrino problems with muon polarization, or
very high energy air showers in the GZK cutoff region
with magnetic bremsstrahlung and pair creation effects
and/or the LPM effect.
PS or pdf manuals are available. (The pdf version is
rather dirty). Important points (especially for those who know Cosmos
already) are printed in red letters.
From uv 6.30, Geomview
is fully suported and the manual for it
is also ready.
