Abstract Type : Oral Abstract Category : Instrumentation and Techniques Abstract : The Cadmium Zinc Telluride Imager (CZTI) is one of the five scientific instruments on Astrosat. It is a coded aperture instrument, primarily aimed at simultaneous imaging and spectroscopy in the 10 - 200 keV X-ray band. CZTI has about 12% energy resolution in mid-band, a wide six-degree field of view, with an angular resolution of few arcminutes. CZTI has a unique capability of measuring X-ray polarization of bright sources. We have thoroughly tested and calibrated the 16,000 pixels of this detector, including imaging and spectroscopic capabilities. The instrument is currently at ISRO Satellite Center and is being integrated with Astrosat. In this talk, I will discuss the overall characteristics and science goals of CZTI, details of the ground calibration, and the promise of X-ray polarimetry. |
