  5. XTDs - X-rayopticsandtransport Thomas Tschentscher, European XFEL, 17 Apr 2012 • offsetmirrors surpressionofbremsstrahlung & higherharmonics • deflectionmirrors distributionto 3 instruments in XHEXP • Monochromators & focusingoptics • X-ray beam diagnostics • Others (pulse picker, split&delay, …)

  6. XHEXP – Scientific Instruments & Optical lasers SPB instrument Eachinstrument will haveitsdevicestobeinterfaced • Severaloptics (mirrors, CRL, monochromators, …) • X-ray beam delivery (slits, attenuators, …) • X-raydiagnostics (Iomonitor, time-diagnostics, …) • Optical laser beam delivery & diagnostics • Sample manipulation & sample environment • Detector(s) andspectrometers • Vacuumsystem & devices Thomas Tschentscher, European XFEL, 17 Apr 2012

  7. Differentiation Users are … • 6 uniquescienceinstruments • Instrument staff • Externalusers • Specificteamswithneedtocontrolandreadouttheirsystems • Beam transport • Optical lasers • Detectors • … The different ‚systems‘ will likelyrequirespecificandsomewhat different implementationbased on platform KARABO. Thomas Tschentscher, European XFEL, 24 Apr 2013

  8. Expert users Some ‚access‘ restrictionmaybeneeded • Complexinstrumentationandcompletedalignment/adjustment • Dangerofdamaginginstrumentation Access limitation • Only ‚experts‘ areallowedtooperatethesedevices (tobeidentified) • Instrument/facilitystaff • Specificstaff, trained in useofspecificdevices • ‚General users‘ mayinitiateactionifneeded for experiment • Bufferedrequest: undulatorgapchange, … • 24/7 or on-callpeopletoexecute • However: thisclassificationis not uniqueandadaption/configurationneeded However, most ‘access’ with the aim of manipulating the experiment will happen from one, maybe two specific working places in the ctrl hutch (surrounded by screens, phone, tools, ...). • Unique control application • Access limitation cannot be achieved by login or similar fundamental ways • SR: limit access to critical devices by passwd or similar Thomas Tschentscher, European XFEL, 24 Apr 2013

  9. Outline • shortdescriptionofelementsof European XFEL userfacility • a ‚prototypical‘ experiment • requirementsto DAQ/Control/Scientific Computing Thomas Tschentscher, European XFEL, 24 Apr 2013

  10. A prototypicalexperiment Preparation phase Setup phase Data taking phase Data analysis phase • Detailedproposal defineparameters, check feasibility • Pre-experiments; preparationof experimental setup • Setup at European XFEL instrument (without beam) • Set & verify x-rayparametersaccordingtorequirements • Alignmentof sample and additional/secondarydiagnostics • Verifyopticallaser beam settingsandperformance • Verifydetectionsystemssettingsandperformance • Search for signal • Time fraction : significant (days) for non-standard exps. • Time fraction : moderate (hrs) for standardexps. • Collectdataaccordingtoexperimentprotocol • Modificationof variables andswitchingofsamples • Apply on-line dataanalysis & reduction • Pre-analysis on-site uptopreliminaryresults • Fullanalysis off-site upto final results Thomas Tschentscher, European XFEL, 24 Apr 2013

  11. Operation modesofinstruments Preparationphase • Beforeexperimentperiod • Clarify setup,requiredinstrumentation, ctrltools, dataanalysistools • Integrate & testnewcomponents • Expectthatsomething (10-20%) comesuponlyatstartofexperiment • This phaseismostly off-line. • Experiment coordinatorwith DAQ/Ctrl/SciCompgroup(s) Thomas Tschentscher, European XFEL, 24 Apr 2013

  12. Operation modesofinstruments Setting upandadjustment • Setup & adjusthardware • Setup & trimsoftware & initialdataanalysistools • Examplesof such tools • Data selection/restriction/reduction • Time orparametersortingmethods • ‚Hit‘ finding • Correlationanalysis • FFT transformations • Fully on-line (occupiesinstrumentto large percentage) • Primary user: • Instrument/facilitystaff • Secondaryuser: • Scientist performingexperiment (external/internal) • Need touseCtrl/DAQ fromseveralcomp‘s (hutch, tunnel, external, ...) Thomas Tschentscher, European XFEL, 24 Apr 2013

  13. Operation modesofinstruments Data taking • Collectdataaccordingtoexperimentprotocol • Modificationof variables andswitchingofsamples • Apply on-line dataanalysis & reduction • Absolute crucialcomponent for experiments ! Needs tobeconsideredpartofexperiment. This taskis different to SR experiments. • ‚Semi-continuously‘ verificationofinstrumentperformance • Facilitystaff • Fully on-line • Primary user: • Scientist performingexperiment (external/internal) • Secondaryuser: • Instrument/facilitystaff Thomas Tschentscher, European XFEL, 24 Apr 2013

  14. Operation modesofinstruments Data analysis • On-line (duringdatataking). See above • Off-line (duringdatataking): Preliminarydatachecks • In ordertoensureweget not swampedwithdataandtoensure high dataqualitystandardsthismaybecome a requirementtotheusers, but will needresourcestobeestablished • Duringthisphaseproximitytoinstrumentisveryhelpful • Off-line (after experiment): Completepreliminaryanalysis • Directly after experiment a preliminarydataanalysisshouldoccur. • Probablyat xfel.eu, but shouldbe remote frominstrument • Off-line (after experiment): Fullanalysis • Occurs after experimentand will require time • Access todatafromhomeinstituteorshortvisitsto xfel.eu Thomas Tschentscher, European XFEL, 24 Apr 2013
