By exploiting low loss cavity resonators, multiple layers of electromagnetic shielding and a micro-Hz bandwidth detection scheme, new exclusion limits could be set. For HSPs, sensitivity was improved by a factor of ~7 compared to previous laboratory experiments.CERN Resonant WISP Search Technology: general issuesbicsscAxion Like ParticlesAxionsElectromagnetic shieldingelektromagnetische AbschirmungHohlraumresonatorenMicrowave photon regenerationMikrowellen Photonen RegenerationNarrow band signal detectionResonators and cavitiesSchmalband-SignalerkennungTechnology: general issuesBetz Michaelauth1311512BOOK9910917177703321The CERN Resonant WISP Search (CROWS)4304145UNINA
