  2. Outline Background WP9 : Safety and Radiation Protection Activity at CERN Project Status and Achievements Training courses, conferences and collaborations Conclusion

  3. Background PhD in nuclear physics performed at IPNO • Experimental study of a nuclear reaction of astrophysical interest • Nuclear experiments with radioactive beams • Detectors and electronics settings • Data taking • Data analysis • Development of an existing code (C++) • Selection of events, coincidences between particles • Theoretical calculations • Monte Carlo simulations (Geant 4) • Optimisation of the experimental setup Teaching assistant in physics at University Paris-Sud

  4. WP9 : Safety and Radiation protection • Vacuum & Cryogenic • HV risks • Radiation levels • Radioactive beams • Neutrons • X-rays emission • Shielding design • Access doors • Interlocks • Fire and gas detection • Radiation levels

  5. Activity at CERN • Arrival : 1st of March 2012 • Radiation Protection analysis (in progress) • Bibliography : comparison to facilities similar to HIE-ISOLDE : ISAC2 @ TRIUMF, ALPI @ Legnaro • Estimation of radiation levels from X-ray emission of RF cavities : dose rate measurements on cavities during RF tests at SM18 • Specification of bulk shielding requirements & design report on the shielding of the future linac • Geometry and access doors to the tunnel with FLUKA simulations SM18 cavity tests FLUKA simulations

  6. Activity at CERN ongoing near future future LINAC2 survey • Radiation Protection study • Follow-up of RP requirements implementation • Assessment of radiation levels due to ion beam losses • Comparison of analytical Monte Carlo codes • Draft parts of the HIE-ISOLDE safety file • Estimation of radioactive waste • Complementary activities and internal networking • X-ray background estimation for MINIBALL experiment • Participation to a survey during a technical stop (RP skills) • Become a CERN guide (in progress)

  7. Deliverables & Milestones

  8. Collaborations Visit to GANIL planned in November 2012 Cavity tests at IPN Orsay Collaboration with TRIUMF in the pipeline : safety file andfeedback from operating facility Collaboration with CEA/LENAC : FLUKA/PHITS comparison for transport of heavy ions

  9. Training & Conferences Attended courses Training courses planned Conferences planned • Radiation Protection Experts certificate delivered by IRA (Lausanne) • Monte Carlo simulations : FLUKA course at Jefferson Lab • Oral english course • Nucleonica training course (October 2012 in Karlsruhe) • AXEL : Introduction to Particle Accelerators (January 2013 at CERN) • ALARA principle (March 2013 at CEA) • Communication and Management course to follow • People 2012 Marie Curie Conference • 2013 IPAC Conference • 2013 Supercomputing in Nuclear Applications and Monte Carlo

  10. Conclusion Evaluation of the tunnel shielding evolving in a good way Timetable is respected up to now Good opportunity for my career development Several networking opportunities : collaborations @ CERN and outside Large panel of formations
