  2. Sirius the next LNLS synchrotron light source Partially removable roof for ID and frontend installation 10 chicanes LINAC Booster Storage ring

  3. Sirius the next LNLS synchrotron light source

  4. Building occupation

  5. Storage ring specifications twenty-fold 5-bend achromat

  6. LINAC specifications

  7. Booster specifications

  8. Storage ring Booster septa LINAC Injection system • Storage ring • 150 MeV Linac • 3 GeV Booster

  9. Bulk shielding for the injection region • Critical spots: • BI – booster injection (150MeV) • BE – booster extraction • SI – storage ring injection 150 MeV LINAC Booster 3 GeV Storage ring

  10. FLUKA simulations Bulk shielding geometry used in simulations Concrete 2.35 g/cm³ Chicane Copper vacuum chamber 26 mm, 1mm wall Synchrotron radiation collimator (steel) Booster ejection local shielding 15 cm steel

  11. FLUKA simulations Bulk shielding geometry used in simulations Chicane RF waveguide passage

  12. FLUKA simulations Bulk shielding geometry used in simulations

  13. Estimated electron losses worst case (3 GeV)

  14. Estimated electron losses • Injection losses inside the SR/booster tunnel during normal operation (topup)

  15. Simulations with FLUKA FLUKA x Swanson without steel local shielding Booster ejection without the local shielding BE

  16. Simulations with FLUKA Effect of the 15 cm steel plate (FLUKA) Dose-eq [pSv/e¯]

  17. Simulations with FLUKA Tunnel chicane Chicane 15 cm steel plate Chicane

  18. FLUKA simulations RF cavity waveguide chicane Waveguide chicane

  19. Preliminarysituation Dose limitgoal: 1 mSv/yr for allworkers Accidents: local shielding Calculationsandstrategies are goingon
