HAWC’s Eye - Implementing hybrid detection by combining a compact Imaging Air-Cherenkov Telescope with the HAWC Gamma-Ray Observatory — •Merlin Schaufel, Thomas Bretz, and Johannes Schumacher — III. Physikalisches Institut, RWTH Aachen University

Combining the techniques of Imaging Air-Cherenkov Telescopes (IACT) with ground based array detectors promise different advantages and new measurements using the complementary shower informations. We developed a compact Silicon Photomultiplier (SiPM) based telescope which was operated in coincidence with the HAWC Gamma-Ray Observatory during July 2017. Performance parameters including the effective area, zenith angle depended trigger response or the effective trigger threshold, usually only accessible by simulation, were directly measured using real air-shower data. Benefiting from the HAWC shower-core reconstruction, a direct measurement of the Cherenkov light density on ground was carried out for the high altitude of 4100 m.

We present the results of this study and discuss possible improvements for energy resolution and the gamma-hadron separation using a hybrid detector.
