- new build system (GNU autotools)
- test version of new hadronic event generator Picco 0.1
- dynamic loading of hadronic models at run-time
Get the hot new version on the
download page. The build system is quite different from before, so be sure to read the README file, and please report any difficulties. Thank you.
- Just an update with QGSJET-II and preshowering.
Fetch the new version on the
download page.
- Check out the new emcfast option, which lets you do a longitudinal shower profile in less than a minute.
- UrQMD-1.3.1 is much (some factor 20) faster than before. Can be used as standard low-energy hadronic model
- do your own tables for CE-equations (with perhaps some modified hadronic interaction code)
- and some more details ... see the userguide

This is a consolidation release, which fixes some problems
before the upcoming new version (1.3).
It concerns an array which in some cases is not completely
deleted before the next shower, and a proper reinitialization
of muon bremsstrahlung cross-sections important
for very inclined showers.
Also an EGS4 file for energies down to 0.1 MeV is given. Fetch
them at the bottom of the
download page.
Thanks to Dmitri (NYU) an uninitialized variable has been found. It affects showers calculated with cascade equations from highest energies on, i.e. fEmax=1. So please check results if you used this option. Please download the
version 1.2.1 and save the file as seneca.F in the src/ directory.
You can download version 1.2 now. New features include QGSJET01, SIBYLL 2.1, UrQMD 1.2.1, and the LPM effect.
Brian drew to my attention, that with the current EGS4 table
one can only go down to 1.0 MeV.
So
here is a new table
for lower energies (0.1 MeV).
And
here for down to 0.01 MeV. The files are also listed in the download section. I havn't tested it, so tell me if something is wrong.
The table must be in the data/ directory under the name EGS4.dat, so be sure to save the old one before renaming it.
The data files (all pp*.dat) are in a binary format. That results
in a non-compatibility with certain machines, because of the
endian-ness. Some use little, some use big endian.
Here is a little
perl-script which
converts one in the other. Just do e.g. "endian ppjqgs.dat ppjqgs_new.dat" and replace the files with the original names in the data/ directory.
A bug concerning very inclined showers has been found
(if you use the CURVED flag).
The step width in
the top of the atmosphere has to
be sufficiently small to ensure precision.
Until there is a next release, please update the main
seneca.F file to version 1.01 by
replacing the file in the src/ directory.
