Abstract

We describe the current status of the High Resolution Fly's Eye detector. Event reconstruction and associated systematics for stereo reconstruction are discussed and recent preliminary results on the study of the composition of ultra-high energy cosmic rays by the Xmax method are presented. These results indicate that the composition of cosmic rays becomes predominantly light near 10¹⁹ eV and beyond.
