Description

Planar pixel sensors based on the Front-End-I4 (FE-I4) read-out developed for the Insertible b-Layer (IBL) are being characterised in laboratory tests and in test beams. Systematic tests are being performed to judge the performance of these sensors and read-out chips. Multiple geometries of pixel sensor have been developed. Laboratory tests include threshold and time-over-threshold tuning as well as source scans to determine bump-bond yield from the module-building process. Both data acquisition systems USBPix, developed at Bonn, and the RCE system, developed at SLAC, have been used to perform characterisations in the laboratory. A selection of modules have been irradiated to fluences expected after 10 years running at 14TeV in the pixel barrel of ATLAS. Both irradiated and un-irradiated modules have been tested in test beams in CERN (80GeV pions) and DESY (4GeV electrons) in conjunction with the EUTelescope. The data from the test beams is being reconstructed and analysed in order to determine efficiency and resolution of the sensors.
