  • Goal of todays MeetingInform about current status and layouts of the analysis modules.(the focus will be on common modules)

    Look specifically into the needs for O2 and H2O analyzers in order to prepare a tender for the instruments.

    and alsoStart the discussion for the other analysis modules.

  • Content of TalkIntroductionAnalysis Module Overview and needs for O2 and H2O analysisATLASCMSLHCbALICEAnalyzer Choices / TenderNext Steps

  • InformationWhat is presented here are (mostly) proposals, they dont represent approved designs.

    The resources (components and manpower) required to make these modules are (mostly) not in the scope of the current work packages.

    In the beginning analysis instruments can be used manually. Fully equipped and automatic analysis modules can be ready for 2nd year of LHC operation.

  • OverviewTwo Types of Analysis Modules Common Analysis Modules for O2, H2O, IR analysis. Receive gas from several sub-detectors, the control is done in the PLC for Auxiliary GasDetector Specific Analysis Modules for O2, H2O, or Monitor chambers. Receive gas from one single sub-detectors. The control is done in the PLC of that sub-detector.

    Note: Analysers that are driven or controlled through the gas system plc,should be defined now so that there existence can be foreseen in the program.Stand alone analysers (e.g. GCs) can be added later provided space and hardware connections have been foreseen.

  • O2 Analyzers TechnologiesElectro-chemical:Can be compatible with all mixtures, but may be not all companies have the same degree of savoir faire.Fuel cells have limited lifetime (~ 1 year)Can be sensitive to pollution in the gasSpecial cells for CO2 (not all suppliers have them)Cheap (5kCHF) transmitter type sensors exist (not really appropriate for remote scanning systems)Sophisticated Instruments (> 8 kCHF) have:automatic ranging (usually required for multi channel systems)automatic calibration (required for high precision measurements)Zirconium oxide:They cannot measure O2 in gas mixtures containing hydrocarbons.Longer lifetime than fuel cellsMore reliable measurementUsually more expensive than fuel cell technology

    Other technologies, e.g. paramagnetic, etc. exist, but they are not so universally useable.

  • H2O Analysers TechnologiesCapacitive:Relatively inexpensive transmitter type sensorsCan be Atex certifiedGood in low range, not so reliable > 1000 ppmCan be destroyed by acids present in the gas

    Wet mirror:Much more reliable Longer lifetime

    Higher priceNot all instruments can measure low range Usually not ATEX certified

  • Next Steps

  • Summary Analyser Needs

  • Tender for O2 and H2O AnalysersExperiments should confirm quantity and provide specs for each analyser.

    The Tender can take into account for each individual analyser.

    We will keep the option to split the contract into several smaller orders.

  • Calendar for TenderPartial or full Approval of layouts and funds for analysis modules by the experiments.Draft technical specification (with individual requirements for each sensor).Approval of technical spec. 30th of June 2006

    Sent out tender (Target date 7th of July 2006)

    Place analyser order September 2006.
