The Geant4 mass model of the ATHENA Silicon Pore Optics and its effect on soft proton scattering
Valentina Fioretti, Andrea Bulgarelli, Simone Lotti +6
Given the unprecedented effective area, the new ATHENA Silicon Pore Optics (SPO) focusing technology, the dynamic and variable L2 environment, where no X-ray mission has flown up t…
Unveiling the origin of XMM-Newton soft proton flares: I. Design and validation of a response matrix for proton spectral analysis
Valentina Fioretti, Teresa Mineo, Simone Lotti +8
Low-energy (<300 keV) protons entering the field of view of XMM-Newton are observed in the form of a sudden increase in the background level, the so-called soft proton flares, affe…
Magnetic shielding of soft protons in future X-ray telescopes: the case of the ATHENA Wide Field Imager
Valentina Fioretti, Andrea Bulgarelli, Silvano Molendi +10
Both the interplanetary space and the Earth magnetosphere are populated by low energy ( keV) protons that are potentially able to scatter on the reflecting surface of Wolt…
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…
Geant4 simulations of soft proton scattering in X-ray optics. A tentative validation using laboratory measurements
Valentina Fioretti, Teresa Mineo, Andrea Bulgarelli +6
Low energy protons (< 300 keV) can enter the field of view of X-ray space telescopes, scatter at small incident angles, and deposit energy on the detector, causing intense backgrou…
The Cryogenic Anticoincidence Detector for ATHENA X-IFU: Preliminary test of AC-S9 towards the Demonstration Model
Matteo D'Andrea, Claudio Macculi, Andrea Argan +9
Our team is developing the Cryogenic Anticoincidence Detector (CryoAC) of the ATHENA X-ray Integral Field Unit (X-IFU). It is a 4-pixels TES-based detector, which will be placed le…
