Performance and spatial resolution of DEPFET detectors as seen in beam test studies

During the past years, the DEPFET collaboration undertook an extensive program of beam test studies as a part of the development of new generations of DEPFET pixel detectors. The beam tests in 2006, 2007 and 2008 on the CERN SPS beam have demonstrated high performance of ILC-type DEPFET matrices: S/N over 100, and spatial resolutions below 2 μm. The extensive data set of the 2008 beam test allowed us to start detailed studies of the detector properties, such as response homogeneity and resolution mapping.
