A more and more detailed description of the physics as implemented in the FLUKA simulation code
is available in the extended manual. This manual is still under
development and a copy in PDF format can be found on this website, just utilize the above link.
To start, please take a look at the current, original FLUKA manual
which is kept in plain ASCII. You find a recent copy of it with the FLUKA package.
In addition a browsable, online version which only differs slightly from
the ASCII original in a few technical aspects is available.
Further, one can find a large range of information on the physics of FLUKA including benchmark
results by consulting the available material from
presentations and publications in connection with
FLUKA. These include a tutorial on FLUKA given at the
MonteCarlo 2000 meeting.
