Pictures of air shower tracks are collected here. They are produced by Nitrogen or Fe primaries of total energy around 10 TeV. Minimum track energy is 500 keV. No neutral particles are included.
The background is transparent or black. In the latter case (B) is attaced. The image format is png. The incident angle is about 0, 20, 45, 70, 85 degrees.

The large angle cases show a lot of albedo particles and thus we see interesting features but are not suited for brouchure. You may also find ineresting ones in Gallery/Yamanashi or in some shot of Movie theator
