Data Analysis For A Balloon Borne Compton Polarimeter, Sambid Kumar Wasti Dec 2020

Data Analysis For A Balloon Borne Compton Polarimeter, Sambid Kumar Wasti

Doctoral Dissertations

The Gamma RAy Polarimeter Experiment (GRAPE), a balloon borne Compton polarimeter for 50-500 keV gamma rays, was successfully flown for the second time in 2014. GRAPE uses events in which a photon scatters between 2 detector elements to measure the polarization of the measured photons. GRAPE consists of 24 collimated polarimeter modules. Each module is made up of 64 rectangular scintillators elements in a grid of 8 × 8 (36 plastic scintillators surrounded by 28 CsI scintillators). GRAPE was flown from Fort Sumner, New Mexico on the morning of September 26th 2014. The experiment was at float altitude for 14.4 …
