  1. Milano, 14 February 2014 ATHENA day BACKGROUND CHARACTERIZATION FABIO GASTALDELLO INAF, IASF-Milano A. DE LUCA, A. GIULIANI, N. LA PALOMBARA, S. MEREGHETTI, S. MOLENDI, A. MORETTI, M. ROSSETTI, D. SPIGA, A. TIENGO

  2. DETAILED STUDIES OF X-RAY BACKGROUND IN MANY PAST AND PRESENT SATELLITES • ANALYSIS OF GEANT 4 SIMULATIONS FOR MISSION STUDIES EXPERTISE

  3. WHY ARE WE OBSESSED WITH BKG ? De Luca & Molendi 04 Detailed knowledge of bkg is crucial to measure faint diffuse X-ray sources: outer regions of clusters and groups and the CXB

  4. REPRODUCIBILITY OF BKG De Luca & Molendi 04 Stability of the spectral shape in time and across the detector is key

  5. IMPORTANCE OF CORNER DATA De Luca & Molendi 04 Snapshot of the particle background at the same time of your obs

  6. PUTTING ALL TOGETHER FOR CLUSTERS Leccardi & Molendi 08

  7. PUTTING ALL TOGETHER FOR CLUSTERS Leccardi & Molendi 08

  8. SWIFT ON A LEO Moretti+09,+11

  9. EFFECT OF THE ORBIT Moretti et al in prep. Higher bkg for high orbit satellites and significant variation due to solar acitivity. In LEO even very different design (Suzaku and Swift) have similar bkg

  10. SOFT PROTONS Tiengo 07

  11. SOFT PROTONS Tiengo 07

  12. SOFT PROTONS XMM-SOC-GEN-TN-0014 Issue 3.3

  13. PROTON MAGNETIC DIVERTER Spiga+07

  14. LESSONS (NOT) LEARNED Branduardi-Raymont+85

  15. CAREFUL CHARACTERIZATION OF THE BKG FOR MANY SATELLITES CAN HELP IN IDENTIFYING PROBLEMS AND PROPOSE SOLUTIONS • BKG WILL BE CRITICAL FOR MANY OF THE SCIENCE GOALS OF ATHENA CONCLUSIONS
