Two common detection techniques are timing arrays and imaging air shower cherenkov telescopes (IACT). Timing arrays yield good directional and energy reconstruction, but provide only mediocre gamma-hadron-separation at their energy threshold. IACTs are good at separation, but since a stereoscopic view of a shower is needed for high reconstruction accuracy, it is difficult to achieve the large effective areas needed for ultra high energy observations. In this work we present the simulations performed to explore and optimize our IACT design and the first steps towards hybrid reconstruction. ; Other ; Published by Verlag Deutsches Elektronen-Synchrotron, Hamburg
