GALI - tracking gamma ray bursts through a network of high-precision sensors (carried out outside the Space Station)

Chief researchers:
Prof. Ehud Behar and Prof. Shlomit Tarem with Ph.D. student Roi Rahin, Department of Physics, Technion
Partners:
Israel Aerospace Industries - Space factory

The main challenge in developing gamma radiation burst detectors is to identify the direction of the burst relative to the observation point. The research team at the Technion has developed a detector system which locates the burst direction better than any existing system of similar size - a 1-liter device. The guiding principle is the use of mutual occultations between small scintillators. The system enables reconstruction of the outburst direction to an accuracy better than -2 ° a degree of accuracy previously achieved only in large detectors on a dedicated satellite.

The Technion team has demonstrated these capabilities in a computer simulation and also in a laboratory model. The system launched on the International Space Station to prove its ability to identify astrophysical bursts. The detector array detected and located gamma-ray radiation while in the Space Station.
