  2. Index • Detector Cooling stations • Chemical analyses • Radiation protection analyses • Sampling procedure : general diagram • Gases • Liquids • Annexes • Sampling form • Naming convention and report storage 17/03/2010 EN/CV/DC

  3. Detector Cooling stations Chemical analyses Radiation Protection analyses 17/03/2010 EN/CV/DC

  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 • H2O 17/03/2010 EN/CV/DC

  5. Radiation Protection Analyses • Regular analyses • To monitor the activation of the fluid • Corrective maintenance • For safety reasons in a non-planned intervention • Estimated time for the analyses: 2 hours (not during nights) • Authorization e-mail with analyses result will be sent to Detector Cooling mailing list Working hours 75252 Non - working hours 74848 17/03/2010 EN/CV/DC
