Abstract: The PILATUS-detector (Pixel Apparatus for the SLS) is a silicon pixel detector consisting of ASIC read-out chips bump bonded to silicon sensors. A dedicated pixel readout chip, SLS06, was developed for the project and leads to excellent performance. One major technological step was the manufacturing of bump-bonded multichip modules consisting of 16 RO-chips with a total of 368x157 pixels. X-rays with energies below 6 keV can be detected in single photon counting mode at a rate of 1 MHz per pixel. Three of these modules were combined and measurements were performed at the PX Beamline 6s of the SLS. The challenges and problems of the technology will be discussed as well as the results of measurements with protein crystals.
