Spectroscopic performance of flight-like DEPFET sensors for Athena's WFI
Johannes Müller-Seidlitz, Robert Andritschke, Michael Bonholzer +6
The Wide Field Imager for the Athena X-ray telescope is composed of two back side illuminated detectors using DEPFET sensors operated in rolling shutter readout mode: A large detec…
Radiation effects and noise evolution in NewAthena WFI flight-production sensors
Valentin Emberger, Johannes Müller-Seidlitz, Luisa Ostler +7
The Wide Field Imager (WFI), one of the two instruments on ESA's next large X-ray observatory NewAthena, is designed for imaging spectroscopy in the 0.2-15 keV range, combining a l…
Characterisation of the NewAthena WFI's DEPFET Flight Production's Operational Parameters
Léonie Sommer, Johannes Müller-Seidlitz, Valentin Emberger +9
NewAthena's Wide Field Imager (WFI) uses detectors made up from Depleted P-Channel Field Effect Transistor (DEPFET) pixels operated in rolling shutter mode. The Large Detector Arra…
Total ionizing dose test with DEPFET sensors for Athena's WFI
Valentin Emberger, Michael Bonholzer, Johannes Müller-Seidlitz +1
The focal plane of Athena's WFI consists of spectroscopic single photon X-ray detectors that contain arrays of DEPFETs (DEpleted P-channel Field-Effect Transistor) as well as ASICs…
Low temperature proton irradiation with DEPFETs for Athena's Wide Field Imager
Valentin Emberger, Robert Andritschke, Parviz Azhdarzadeh +5
