Abstract

We are furthering our GRAINE project. This balloon experiment was performed using a telescope with a 12.5cm×10cm aperture area and a 4.3hour (1.6hours@35km) flight duration in 2011. Working tests of each element and connection tests between elements were performed. Atmospheric gamma-ray flux was measured. The first demonstration of an emulsion gamma-ray telescope was described using flight data in our 2011 balloon experiment.
