Abstract

The International X-ray Observatory (IXO) will be a Joint X-ray observatory mission by ESA NASA and JAXA It will have a large effective area (3 m(2) at 1 25 key) grazing incidence mirror system with good angular resolution (5 arcsec at 0 1-10 keV) and will feature a comprehensive suite of scientific instruments an X-ray Microcalorimeter Spectrometer a High Time Resolution Spectrometer an X-ray Polarimeter an X-ray Grating Spectrometer a Hard X-ray Imager and a Wide-Field ImagerThe Wide Field Imager (WFI) has a field-of-view of 18 ft x 18 ft It will be sensitive between 01 and 15 keV offer the full angular resolution of the mirrors and good energy resolution The WFI will be Implemented as a 6 in wafer-scale monolithical array of 1024 x 1024 pixels 01 100 x 100 mu m(2) size The DEpleted P-channel Field-Effect Transistors (DEPFET) forming the individual pixels are devices combining the functionalities of both detector and amplifier Signal electrons are collected in a potential well below the transistor s gate modulating the transistor current Even when the device is powered off the signal charge is collected and kept in the potential well below the gate until it is explicitly cleared This makes flexible and fast readout modes possible (C) 2010 Elsevier B V All rights reserved
