Abstract
The present document is aimed at providing a complete description of all the work and outcome done during the AREMBES Core Technology Program (CTP) project that has been kicked-off on March 21st, 2016. AREMBES is the acronym for “ATHENA Radiation Environment Models and X-ray Background Effects Simulators” which is a project carried out under the ESA Contract No. 4000116655/16/NL/BW [AD1] and successive CCN1 [AD2]. The reference space mission which is the bone of the present CTP project is Athena, the 2nd ESA Large Class mission to be launched on early 2030’s. The main tasks carried out have been: characterization of L2 particle environment; optimization of a new physics list for Athena aims; development of a user-friendly simulator framework to perform simulation of particle interaction with payload/detectors. During the development of the project, a CCN1 has been also put in place ([AD2], 16/05/2017) addressing the necessity in expanding the knowledge of the particle environment also at the L1 Lagrangian Point, beyond the baselined L2 one. The main outcomes of the AREMBES project have been: 1) the detailed study of L2 vs L1 particle environment (ESA – ASST have taken into account also this study to take in the close future a final decision about the Athena satellite orbit) 2) the creation of the Geant4 Space Physics List (ESA has endorsed this List as the reference to be used in Athena NXB Geant4 assessment study) 3) the creation of the “core” of the Simulator Framework 4) the creation of the mass models of the two focal plane instruments and the Athena optics and flight module 5) to contribute up to 23 publication on peer reviewed journals, conferences proceeding, citations from/to AREMBES, etc (see Annex 1 for details) The present report is structured as follows: §1 Comprehensive introduction of the context §2 Description of the programme of work §3 Description of the activities performed, and main results achieved §4 Open issues, bugs and recommendations for future work related to the ASF
