Abstract A modular test facility for the investigation of thermoacoustic phenomena has been constructed in Berlin, which exhibits the accuracy of laboratory experiments with well defined boundary conditions. Moreover, the facility provides independent control of temperature, operating pressure and flow velocity up to a range relevant for real gas turbine applications. The unique facility is decribed in detail with an emphasis on instrumentation to be used for acoustic investigations and the data assessment procedure for the investigation of bias flow liner damping characteristics as the primary reasearch target for the initial operation. An outlook is given with respect to options und upgrades planned for the future.
