Stratospheric Spectropolarimeter Gamma-X (SSGX)

Among the frontiers of astronomy are the polarization measurements of x- and γ-rays, emitted from phenomena such as γ-ray bursts, pulsars, and active galactic nuclei. Our payload utilizes a 4x4 pixel CdTe array developed to characterize background radiation in the 20-1000 keV energy range. SSGX features both the CACTμS detection unit (previously launched from Italy in 2002) and an innovative electronic data collection system designed by ARC students. DAISI samples detector analog voltages, supp
