Abstract :
Thin Gap Gas Chambers were proposed for a possible upgrade of the end-caps of the DELPHI detector at LEP. Two full prototypes were built and tested at the CERN 20 GeV/c SPS pion beam. The main construction parameters of the detector and the on-board front-end electronics characteristics are reviewed. Test beam results from the full prototypes, showing the general feasibility of the detector, will be presented.
