A closed booster prototype for MADMAX: CB100 — •Chang Lee for the MADMAX collaboration — Max Planck Institute for Physics, Munich, Germany

CB-100 is a closed dielectric haloscope that aims to verify the dielectric haloscope concept. We use the setup to understand the reflectivity and thermal noise of a dielectric haloscope, which is a prerequisite for a good calibration. The MADMAX collaboration plans to use the system for its axion-like particle dark matter search using the MORPURGO magnet at CERN. We present the concept, design, and construction of CB-100. We also present the reflectivity measurement at room temperature and 4K.
