A prototype 4D-tracking demonstrator based on the TimeSPOT developments

We present first results obtained with a prototype 4D -tracking demonstrator, using sensors and electronics developed within the TimeSPOT project, and tested on a positive charged pion beam at CERN SPS. The setup consists of five small tracking layers in a row, having area of about 3 mm2 each, three of which equipped with 3D -trench silicon sensors and two with 3D -column diamond sensors. The five layers are then read-out by a KC705 Xilinx board on a PC. We describe the demonstrator structure and operation and illustrate preliminary results on its tracking capabilities.
