The interaction of terawatt laser pulses with suitable gas or foil targets can yield bunches with up to 10^12 particles (e.g. protons) in the MeV region. For studies of these processes a position sensitive detector has been developed which is capable of detecting single charged particles as well as extremely intense bunches. The detector consists of an ionization chamber with a position-sensitive pad anode-plane and an additional proportional-chamber stage with a multi-wire anode plane. A Camac-based DAQ system is under preparation. First data taken using a laser-induced plasma as a particle source at the Institute for Laser and Plasma Physics at the University of Düsseldorf, are presented and discussed.
