Abstract :
The GridPix detector is an assembly of a TimePix pixel chip, covered with a layer of silicon rich silicon nitride (SiRN) as protection against discharges, an integrated MPGD grid (InGrid), a drift gap and a cathode plane. GridPix detectors have been tested using a test beam at DESY. Measurements have been performed on single electron efficiency, time walk and robustness against discharges. Gossip is a GridPix detector with a drift gap of ~1mm. The concept is to replace the silicon in vertex detectors by ~1mm of gas. Gossip has been tested in a test beam at CERN and preliminary results are in agreement with simulations. DICE is a GridPix detector with a drift gap of ~2cm and is used for nuclear research at the TU Delft. DICE also has been used as reference detector for testing Gossip detectors in a test beam.
