Laser driven plasma accelerators provide pulsed particle bunches with specific properties concerning spectrum as well as divergence and spatial distribution. Common diagnostic principles used in the laser plasma accelerator community will be reiviewed in these lectures. Typically, magnetic spectrometers with a variety of electronic, optical or film detectors are implemented or time of flight schemes are used. Thereby, main challenges are due to the harsh environment conditions of laser plasma experiments that demand special measures to cope with high bunch charge beams, background radiation and electromagnetic noise. Finally, concepts for absolute dosimetry in laser driven radio-biological studies will be discussed.
