CERN@school gamma candidate clusters.

The gamma (photon) candidate clusters, in .png format, as they would be detected by a Timepix hybrid silicon pixel detector. These patterns occur when a photon hits the centre (monopixel), edge (bipixel) or corner (tripixel and tetrapixel) of a pixel in the Timepix detector. Note that other tri- and tetrapixel clusters may be produced by other kinds of particles (e.g. betas) - and that these should not be counted as gammas. Colour and monochrome versions have been provided for convenience.
