In September 2008 the SLIM5 collaboration submitted a low material budget silicon demonstrator to test with 12 GeV/c protons, at the PS-T9 test-beam at CERN. Two different detectors were placed as DUTs inside a high-resolution and fast-read out beam telescope. The first DUT was a high resistivity double-sided silicon detector, with short strips (‘‘striplets’’)and with reduced thickness, at 453 angle to the detector’s edge, readout by the data-driven FSSR2 chip. The other one was a 4k-Pixel Matrix of Deep N Well MAPS, developed in a 130 nm CMOS Technology, providing digital sparsified readout. In the following, I present the striplets and also the beam telescope characteristics, with some details about the front end readout (based on the FSSR2 chip)and some preliminary results of the data-analysis.
