Title: | X-IFU background calibration plan | Authors: | LOTTI, Simone | Issue Date: | 2021 | Number: | TN_INAF_AHEAD_2021_001 | Abstract: | The particle background can be considered as a calibration source (the galactic cosmic ray flux) for the X-IFU instrument. The standard X-IFU background spectrum in closed observations is induced by three different components (protons, alpha particles and electrons), that can be modeled as a continuum power law spectrum plus some gaussian emission lines due to fluorescence and escape peaks1 . The three components can have different variations along the solar cycle, and should in principle be modeled independently. Even when used to fit a single component, the “power law + gaussians” model is an empirical model resulting from the superimposition of different background spectra induced by the different particle populations impacting on the detector as a result of the primary particle species. Background calibration sources: - Ahepam o Protons o Alpha o Electrons - WFI - X-IFU high energy band - CryoAC - Filter wheel closed time observations - Other satellites The aim of this document is to produce a global model of the background that will allow us to put together all the information from the different calibration sources to produce a reliable estimate of the background during an observation. | URI: | http://hdl.handle.net/20.500.12386/35094 | Fulltext: | reserved |
