I was once very  interested in high energy cosmic rays and extensive air 
showers. Things like the Haverah Park array in Nottinghamshire,
the Flys Eye array and the underwater photomultiplier arrays.

The upper bound to gamma ray energy is quite impressive - I may be wrong,
but the same kinetic energy as a speeding locomotive.

ps. this is on topic, as I guess Linux is used for DAQ on these things 
these days :-)
