1. EN/CV/DC Fluid analyses and Radiation Protection monitoring Presentation done by Elena Perez Rodriguez For further information contact elena.perez.rodriguez@cern.ch Radiation Protection and Chemical Analyses for the maintenance plan

2. Index Introduction Chemical analyses Radiation protection analyses Sampling procedure : general diagram – Gases – Liquids Annexes – Sampling form – Documentation – Contact persons EN/CV/DC 215/04/2010

3. Introduction The quality requirements of the fluid are controlled at the supply. To control the evolution of some chemical properties, especially interesting for the detector, chemical analyses can be demanded (see sampling form). To monitor the activation of the fluid, Radiation Protection will do regular analyses to ALL the stations. 3 EN/CV/DC PFC liquid (C6F14) Pixel Preshower 1&2 Silicon Strip 1&2 Thermal Screen 1&2 Water BrineTIF 15/04/2010

4. Chemical Analyses Regular analyses – To monitor the chemical quality of the fluid. – Requested by the experiment. – Fluorocarbon analyses Organic Purity Other perfluorocarbons H containing molecules or grease Acidity Prepolimers 4 EN/CV/DC 15/04/2010

5. Regular analyses – To monitor the activation of the fluid. – To ALL the stations. Corrective maintenance – For safety reasons in a non-planned intervention. – Estimated time for the analyses during working hours: 2 hours – Estimated time for the analyses during not working hours: 3 hours – Authorization e-mail with analyses result will be sent to Detector Cooling mailing list Radiation Protection Analyses 5 EN/CV/DC Working hours 75252 Non - working hours 74848 15/04/2010
