The Athena X-ray Integral Field Unit
Didier Barret, Thien Lam Trong, Jan-Willem den Herder +100
The X-ray Integral Field Unit (X-IFU) is the high resolution X-ray spectrometer of the ESA Athena X-ray observatory. Over a field of view of 5' equivalent diameter, it will deliver…
Energy scale calibration and drift correction of the X-IFU
Edoardo Cucchetti, Megan E. Eckart, Philippe Peille +6
The Athena X-Ray Integral Field Unit (X-IFU) will provide spatially resolved high-resolution spectroscopy (2.5 eV FWHM up to 7 keV) over the 0.2 to 12 keV energy band. It will comp…
Testing the X-IFU calibration requirements: an example for quantum efficiency and energy resolution
Edoardo Cucchetti, François Pajot, Etienne Pointecouteau +9
With its array of 3840 Transition Edge Sensors (TESs) operated at 90 mK, the X-Ray Integral Field Unit (X-IFU) on board the ESA L2 mission Athena will provide spatially resolved hi…
Reproducibility and monitoring of the instrumental particle background for the X-Ray Integral Field Unit
Edoardo Cucchetti, Etienne Pointecouteau, Didier Barret +7
The X-ray Integral Field Unit (X-IFU) is the cryogenic imaging spectrometer on board the future X-ray observatory \textsl{Athena}. With a hexagonal array of 3840 AC-biased Transiti…
