Accelerated charges radiate.
It is proposed, over the next few months, to develop a site of classic bubble chamber pictures - described carefully so that they can be used for teaching purposes without too much preparation. In the meantime, here are a few (some with descriptions, some not):
Electromagnetic shower with interesting positrons.
Positron mass from delta ray - back page
of CATALYST April 1998.
Positron annihilating in flight - photon materialises.
Cosmic rays cradling particle interaction.
