Imaging and spectroscopic performances of the Silicon Drift Detector of the Wide Field Monitor
On demand | Presenting live 19 June 2024 
Abstract
Despite being a one-dimensional device by design, large-area linear Silicon Drift Detectors may exploit the diffusion of the charge cloud produced by an interacting photon to determine its two-dimensional impact position as well as its energy. Therefore, they can operate as spectral-imaging devices, which are particularly suitable for space-based X-ray coded-mask instruments, for which the trade-off between large collecting area, number of readout channels and spatial resolution is a challenge. We describe the experimental characterization of the photon reconstruction capabilities of a 169 µm anode-pitch large-area linear Silicon Drift Detector, whose technology is the foundation of the Wide Field Monitor camera of the eXTP, STROBE-X and LEM-X space missions.

Francesco Ceraudo is a researcher at the Italian National Institute for Astrophysics. His main field of research is the characterization of state-of-the-art instrumentation for X-ray space astronomy, especially Silicon Drift Detectors and Micro-Pore Optics. He has worked on such projects as the Pixelated Silicon Drift Detector (PixDD), the Large Area Detector (LAD) of the eXTP mission, and the Wide Field Monitor of the eXTP, STROBE-X and LEM-X missions. He has a long experience in the development of software for instrumentation control, data analysis, radiation campaign, and simulation of instrument performances under various conditions and at different phases of the life of the mission.
