Scope of Ph.D.

In the field of high-resolution, large-bandwidth calorimetry the metallic magnetic calorimeters play a leading role. With a maximum resolution of single digit eV and a bandwidth of 10th of keV, they qualify themselve for numerous experiments. Operating the sensor at lowest temperature of about 20 mK the resolution reaches the optimum, but the difficulty of readout increases. The ECHo experiment aims to determine the scale of Neurinos mass utilizing the energy resolution and high decay statistics. The statistics rely on a large amount of calorimeters read out with a frequency multiplex scheme. Within my Ph.D. I develop a FPGA based Software-defined Radio as a sensor interface and data aquisitision system. The developed system will cover 6000 readout channels for the ECho-100k experiment.
