The Wide Field Imager for the Athena X-ray Observatory

Project Details

Description

The WFI is one of the two scientific instruments proposed for Athena, the mission selected to address the “Hot and Energetic Universe” science theme identified by ESA (Athena@ESA) for its L2 large satellite mission with launch in 2028.
The WFI will provide imaging in the 0.2-15 keV energy band over a wide field, simultaneously with spectrally and time-resolved photon counting. The instrument is designed to make optimal use of the grasp (product of collecting area and solid angle) provided by the optical design of the ATHENA mirror system, by combining a sensitive approx. 40’x40' field of view DEPFET detector with a pixel size properly sampling the angular resolution of 5’’ on-axis (half energy width).
