ATHENA

Mission Overview

ATHENA, the Advanced Telescope for High ENergy Astrophysics, will be developed as L-Class mission for launch in 2028. The Wide-Field Imager (WFI) is proposed as its imaging camera. The WFI will provide imaging in the 0.1-15 keV energy band over a wide field, simultaneously with spectrally and time-resolved photon counting. The instrument is designed to make optimal use of ATHENA mirror system, providing a 40'x40' field of view with an angular resolution of 5". The WFI is a very powerful survey instrument, significantly surpassing currently existing capabilities. In addition, the WFI will provide unprecedented simultaneous high-time resolution and high count rate capabilities for the observation of bright sources with low pile-up and high efficiency.
Our institute is highly interested in this X-ray observatory, as it is key to combine measurements from different wavelength regimes to unveil the objects to be studied, such as star formation regions.

Contribution of our Team

We will contribute the ICPU (Instrument Control and Power Supply Unit) SW to the ATHENA Wide-Field Imager. Corresponding hardware will come from our partners IWF/RUAG as well as from international partners (e.g. filter wheel controller, harness). The flight software which will be developed in house. As main processor we foresee to use ESA's new payload data processor SSDP (Scalable Sensor Data Processor). Our developments build on our CHEOPS and ASAP LeanOS expertise.
