Development of the GEM-TPC X-ray Polarimeter with the Scalable Readout System

Development of the GEM-TPC X-ray Polarimeter with the Scalable Readout System

We have developed a gaseous Time Projection Chamber (TPC) containing a single-layered foil of a gas electron multiplier (GEM) to open up a new window on cosmic X-ray polarimetry in the 2–10 keV band. The micro-pattern TPC polarimeter in combination with the Scalable Readout System produced by the RD...
