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. 517 $aCERN Resonant WISP Search 606 $aTechnology: general issues$2bicssc 610 $aAxion Like Particles 610 $aAxions 610 $aElectromagnetic shielding 610 $aelektromagnetische Abschirmung 610 $aHohlraumresonatoren 610 $aMicrowave photon regeneration 610 $aMikrowellen Photonen Regeneration 610 $aNarrow band signal detection 610 $aResonators and cavities 610 $aSchmalband-Signalerkennung 615 7$aTechnology: general issues 700 $aBetz$b Michael$4auth$01311512 906 $aBOOK 912 $a9910917177703321 996 $aThe CERN Resonant WISP Search (CROWS)$94304145 997 $aUNINA
