2. 2 Recent achievement We are ready for 2009 LHC HW and Operation commissioning tests and for the 2009 LHC Run period All safety systems have been maintained / upgraded and are receptionned All safety systems have been maintained / upgraded and are receptionned LACS/LASS and SSA (Systeme de surete ATLAS) have been upgraded and are ready for operation LACS/LASS and SSA (Systeme de surete ATLAS) have been upgraded and are ready for operation FPIAA project (Sofia, Nuno, Xavier) FPIAA project (Sofia, Nuno, Xavier) Phase 2 installation has been completed: sensors coverage extended now to the forward trenches, the Big Wheels gangways and the Open Configuration scaffolding zones

3. 3 Recent achievement ATLAS cavern protection campaign against accidental He release in the LHC machine is finished (Nuno, Dimi, Raphael) ATLAS cavern protection campaign against accidental He release in the LHC machine is finished (Nuno, Dimi, Raphael)  Q1, Q2 survey holes have been protected and sealed: 110 mbars pressure resistant, special cut outs for survey equipment, ALARA principle respected

4. 4 Recent achievement  Survey galleries end of zone doors and walls have been redesigned: fire resistant, 110 mbars pressure resistant, sealed, with special cut out for the survey equipment, ALARA principle respected  A protection of the TAS area has been designed and installed : 110 mbars pressure resistant, ALARA principle respected, sealed

5. 5 Recent achievement  US15 / UX15 end of zone doors have been changed to be fire resistant and 110 mbars pressure resistant and sealed.  All ventilation doors are monitored and connected to LACS and LASS  The US15/UX15 and USA15/UX15 holes have been sealed

6. 6 Recent achievement ATLAS Pressure sensors installation (Fernando, Jan) ATLAS Pressure sensors installation (Fernando, Jan) In collaboration with EN-CV, additional pressure pipes and sensors have been installed to monitor the overpressure between the caverns UX15, US15, USA15 and the tunnel sectors. The overpressures will be monitored and and controlled at SLIMOS desk to identify a possible RP Water leak detection system in racks is installed (Fernando, Charles) Water leak detection system in racks is installed (Fernando, Charles)

7. 7 Recent achievement Gate monitors at UX15 entrance and at SDX1 Buffer zone entrance installed and operational at SLIMOS desk (Serguei, Tatiana) Gate monitors at UX15 entrance and at SDX1 Buffer zone entrance installed and operational at SLIMOS desk (Serguei, Tatiana)

8. 8 Future development and activities AL3 alarms safety system need under investigation AL3 alarms safety system need under investigation This system will be required to implement the ATLAS safety matrixes in a compatible way with RP requirements (especially different ventilation matrix in case of UX15 Closed or Open mode) Overpressure test campaign in collaboration with EN-CV group Overpressure test campaign in collaboration with EN-CV group Planned end of September to control that the overpressure requirements between the tunnel, US15 service cavern, UX15 cavern and USA15 service area are met. Final ID CO2 test campaign with the shafts closed and ventilation in LHC run mode (air recycling). Final ID CO2 test campaign with the shafts closed and ventilation in LHC run mode (air recycling).

9. 9 Future development and activities FPIAA project upgrade : FPIAA project upgrade : Replacement of the sensors supports and sensors connectivity to minimize the replacement and disconnecting time (ALARA) Creation of the Surface Radioactive Buffer Zone Creation of the Surface Radioactive Buffer Zone To be ready for the 2010 Shutdown period SLIMOS desk improvement SLIMOS desk improvement Patrols : Patrollers training and shifts start up Patrols : Patrollers training and shifts start up General ATLAS training to be revised General ATLAS training to be revised Configuration control / seismic analyses Configuration control / seismic analyses

10. 10 Future development and activities ALARA activities : ALARA activities :  Analysis of the ATLAS closure activities is on going  Analysis of the specific activities for the coming shutdown period  Development of a strategy and procedures to control all ALARA aspects for the persons and per activity, development of the associated personnel database.  Augmented reality project : A pilot project is run to evaluate a tool to minimize the time of intervention for specific maintenance in highest radioactive regions of the detector
