Synchronized analysis of testbeam data with the Judith software

The Judith software performs pixel detector analysis tasks utilizing two different data streams such as those produced by the reference and tested devices typically found in a testbeam. This software addresses and fixes problems arising from the desynchronization of the two simultaneously triggered data streams by detecting missed triggers in either of the streams. The software can perform all tasks required to generate particle tracks using multiple detector planes: it can align the planes, cluster hits and generate tracks from these clusters. This information can then be used to measure the properties of a particle detector with very fine spatial resolution. It was tested at DESY in the Kartel telescope, a silicon tracking detector, with ATLAS Diamond Beam Monitor modules as a device under test.
