The international linear collider, ILC, is an e+e− collider of the next generation. Planned in international cooperation this machine and its experiments will operate at the forefront of science and provide novel and deep insight into the most fundamental aspects of nature, complementing and extending the capabilities of the LHC (the hadron-hadron collider under construction at CERN). The goal of the proposed Nachwuchsgruppe is to prepare the experimental program scientifically and technically. Among the most fundamental questions is that of the origin of the breaking of the electroweak symmetry, and the existence of possible new symmetries. Answering these questions requires new investigative methods, combined with the most advanced detector technologies. The development of a particular new approach, called particle flow, is essential for the experimental program and requires the synergy of detector R&D, and software and simulation developments. The central topic of the proposed a Nachwuchsgruppe work is the proof of principle of the particle flow approach. A particular challenge in this context is the design and the construction of the calorimeter, a system able to measure the energy of each particle product of the e+e− collision. A device with unprecedented granularity and resolution is required. This can only be realized with new detection methods. The detector proposed here is based on a readout system with newly developed silicon-based photo detectors (SiPM). DESY in collaboration with international partners has pioneered this new technology. At the core of this program are the test of a large hadroniccalorimeter prototype equipped with SiPM, and the investigation and improvement of photo detector technologies. A close collaboration with the Shinshu University in Japan ensures that tight connections are available to a laboratory working at the forefront of modern photo detector developments. The group will also investigate how new photo detectors can be applied in other fields, i.e. medicine (PET). The work of this group will be closely integrated into an already existing international collaboration, with strong cooperation with the universities of Hamburg, Heidelberg and Shinshu.
