Zusammenfassung: | <jats:title>Abstract</jats:title> <jats:p>The Water Cherenkov Detector Array (WCDA) is a major component of the Large High Altitude Air Shower Array Observatory (LHAASO), a new generation cosmic-ray experiment with unprecedented sensitivity, currently under construction. WCDA is aimed at the study of TeV <jats:inline-formula> <jats:tex-math><?CDATA $\gamma$?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="cpc_44_6_065001_M1.jpg" xlink:type="simple" /> </jats:inline-formula>-rays.

Most of them are Galactic sources, and the extragalactic sources are Active Galactic Nuclei (AGN). </jats:p> |
