A gamma-ray burst polarimeter (GRBP) is being developed at NASA Goddard Space Flight Center for measuring the Xray polarization of energetic transients in the 2 - 10 keV energy range. The primary goal is to measure the polarization of the prompt X-ray emission from gamma-ray bursts (GRBs) in order to distinguish between the possible emission mechanisms. The instrument could also be capable of measuring polarization from other X-ray transients, such as soft gamma repeaters (SGRs) or black hole transients. An instrument with a wide field of view is required to detect transient events and a large collecting area is required to have sufficient sensitivity. The GRBP is a time projection chamber (TPC) that uses negative ions as a charge carrier enabling a large volume, high spatial resolution detector. We describe a GRBP prototype that is suitable for a sounding rocket measurement of the Crab Nebula or for measurements of bright transient sources from a small satellite.
