AIRES Cosmic Ray Showers
Maximo Ave, Dinoj Surendran, Tokonatsu Yamamoto, Randy Landsberg, and Mark SubbaRao created the following visualizations of showers created using Sergio Sciutto's AIRES package. The AIRES source code was modified so it output intermediate particle positions, and these were then processed with a Perl script to Partiview format.
This page has downloads of several showers, and documentation. The showers work in Linux and Windows, and in side-by-side stereo i.e. on a geowall. Everything here is released under Creative Commons License 2.5.
Shown above is an AIRES simulation of what happens when a proton with 1Tev of energy hits the atmosphere about 20km above the ground. The shower is in a 20km x 5km x 5km box superimposed on a scale map of Chicago's lakefront. The picture for that was obtained from the TerraServer site. Different kinds of particles are colored differently. For example, here, electrons and positrons are green, muons are red, and gamma rays are cyan.
MoviesThese movies here are in MPEG format, and should work on any computer.
Animated 3d Models
Below are interactive showers that you can spin/zoom/move while they, well, shower. Unless otherwise stated, they work on Windows and Linux (OS X version to come, email us if you want it yesterday), and in passive stereo e.g. on a geowall. Each comes with a README.TXT file that has information on how to run it, what the colors mean, etc.
They also come with the interactive viewing freeware Partiview.
Instructions on how to make your own showers can be found here.
How to modify the picture of the ground
Change the file ground.sgi to whatever picture you want. You'll probably want to use a picture representing the same ground area, which is 8km x 8km. You can get a picture from TerraServer, for example.
How to show subshowers
You can turn on/off showers of various types, by typing commands like
g1 only= type 1 -2
in the command window. This turns on all particles of type 1 and -2. As you can see from the Table below (compiled from Table 2.3 on page 21 of the AIRES Users Manual), this turns on only gamma rays and electrons.
