(Instituto Superior Técnico\, Li sbon\, Portugal)\nIon beam analysis is a quantitative analytical group of techniques\, and the purpose of this lecture is to show how to avoid many pitfalls that often prevent IBA techniques from determining elemental dept h profiles accurately. In fact\, IBA is fraught with pitfalls. There are v ery many things that can be done wrong or simply go wrong unless great car e is taken. We will first address pitfalls coming from experimental issues \, namely: lost beam and events\, calibration of fixed parameters\, unwant ed target-beam interactions\, and other effects. These are not only releva nt\, but in fact essential to data analysis\, because problematic data tha t are not what the analyst thinks it is\, will lead to wrong conclusions\, and it is often possible to identify issues in the data during data ana lysis. Then we will address pitfalls related to data analysis itself. With codes such as NDF (DataFurnace)\, that include a great deal of advanced p hysics and effects\, and allow the user to fit parameters such as beam ene rgy\, angles of scattering and of incidence\, or even the stopping powers and cross sections\, the scope for error increased enormously. At the same time\, many new IBA users no longer have a heavy background in nuclear or ion beam physics\, and reliance on computer programs is a given. We will use real life examples to illustrate some of the most common pitfalls in I BA data analysis\, along with steps that can be taken to prevent or remedy such problems.\n\n//indico.ictp.it/event/7638/session/2/contribution/12 LOCATION:ICTP LB (Euler Lecture Hall) URL://indico.ictp.it/event/7638/session/2/contribution/12 END:VEVENT BEGIN:VEVENT SUMMARY:Pitfalls in IBA data analysis (II) - Calculation of uncertainty bu dget DTSTART;VALUE=DATE-TIME:20160928T073000Z DTEND;VALUE=DATE-TIME:20160928T083000Z DTSTAMP;VALUE=DATE-TIME:20260419T043854Z UID:indico-contribution-2-0-13@ictp.it DESCRIPTION:Speakers: BARRADAS\, Nuno P. (Instituto Superior Técnico\, Li sbon\, Portugal)\nOne of the advantages of IBA techniques over many other competitive techniques is that quantification can often be made from first principles\, leading to claims of high traceable accuracy. However\, many published works do not quote uncertainties on the values reported\, and w hen they do\, it is very common that the uncertainties quoted reflect only the statistics of the experiment. In fact\, statistics is just one source of uncertainty in IBA experiments\, and almost always not the most import ant. The uncertainty budget is specified as a formal approach to the syste matic evaluation of the uncertainty of a measurement. It is the statement of a measurement uncertainty\, of the components of that measurement uncer tainty and of their calculation and combination. The concepts involved wil l be described with special reference to IBA\, and practical examples will be developed\, explaining the practical steps of how to calculate realist ic uncertainties in IBA.\n\n//indico.ictp.it/event/7638/session/2/contribu tion/13 LOCATION:ICTP LB (Euler Lecture Hall) URL://indico.ictp.it/event/7638/session/2/contribution/13 END:VEVENT BEGIN:VEVENT SUMMARY:Secondary Ion Mass Spectroscopy - SIMS\, Cluster-SIMS and MeV-SIMS DTSTART;VALUE=DATE-TIME:20160928T090000Z DTEND;VALUE=DATE-TIME:20160928T100000Z DTSTAMP;VALUE=DATE-TIME:20260419T043854Z UID:indico-contribution-2-0-14@ictp.it DESCRIPTION:Speakers: WEBB\, Roger (University of Surrey\, Guildford\, UK) \nThe basic concepts behind SIMS will be provided. The underlying models o f the molecular and ion ejection process will be given. The similarities a nd differences between MeV-SIMS and the more conventional cluster keV-SIMS will be given. Simulations of molecular ejection from molecular material due to deposited energy spikes will be used to demonstrate the underlying physical mechanisms behind the MeV and cluster keV-SIMS process. A descrip tion of what can be expected to be achieved from MeV-SIMS and cluster SIMS and their position in the great collection of materials analysis techniqu es in existence today. Comparison is made with other molecular concentrati on mapping techniques.\n\n//indico.ictp.it/event/7638/session/2/contributi on/14 LOCATION:ICTP LB (Euler Lecture Hall) URL://indico.ictp.it/event/7638/session/2/contribution/14 END:VEVENT BEGIN:VEVENT SUMMARY:Bus transfer to Synchrotron Elettra DTSTART;VALUE=DATE-TIME:20160928T110000Z DTEND;VALUE=DATE-TIME:20160928T120000Z DTSTAMP;VALUE=DATE-TIME:20260419T043854Z UID:indico-contribution-2-2-15@ictp.it DESCRIPTION:Speakers: \nPick up from LB parking lot at 13:15\n\n//indico.i ctp.it/event/7638/session/2/contribution/15 LOCATION:Elettra Sincrotrone Trieste URL://indico.ictp.it/event/7638/session/2/contribution/15 END:VEVENT BEGIN:VEVENT SUMMARY:Welcome and overview of Synchrotron-based analytical techniques an d Elettra DTSTART;VALUE=DATE-TIME:20160928T120000Z DTEND;VALUE=DATE-TIME:20160928T130000Z DTSTAMP;VALUE=DATE-TIME:20260419T043854Z UID:indico-contribution-2-2-27@ictp.it DESCRIPTION:Speakers: GREGORATTI\, Luca (Elettra Sincrotrone Trieste)\n//i ndico.ictp.it/event/7638/session/2/contribution/27 LOCATION:Elettra Sincrotrone Trieste URL://indico.ictp.it/event/7638/session/2/contribution/27 END:VEVENT BEGIN:VEVENT SUMMARY:Laboratory visit DTSTART;VALUE=DATE-TIME:20160928T130000Z DTEND;VALUE=DATE-TIME:20160928T140000Z DTSTAMP;VALUE=DATE-TIME:20260419T043854Z UID:indico-contribution-2-2-28@ictp.it DESCRIPTION:Speakers: GREGORATTI\, Luca (Elettra Sincrotrone Trieste)\n//i ndico.ictp.it/event/7638/session/2/contribution/28 LOCATION:Elettra Sincrotrone Trieste URL://indico.ictp.it/event/7638/session/2/contribution/28 END:VEVENT BEGIN:VEVENT SUMMARY:The SYRMEP X-ray imaging beamline at Elettra: recent achievements and future perspectives DTSTART;VALUE=DATE-TIME:20160928T140000Z DTEND;VALUE=DATE-TIME:20160928T143000Z DTSTAMP;VALUE=DATE-TIME:20260419T043854Z UID:indico-contribution-2-2-29@ictp.it DESCRIPTION:Speakers: TROMBA\, Giuliana (Elettra Sincrotrone Trieste)\n//i ndico.ictp.it/event/7638/session/2/contribution/29 LOCATION:Elettra Sincrotrone Trieste URL://indico.ictp.it/event/7638/session/2/contribution/29 END:VEVENT BEGIN:VEVENT SUMMARY:Presentation of the TwinMic beamline DTSTART;VALUE=DATE-TIME:20160928T143000Z DTEND;VALUE=DATE-TIME:20160928T153000Z DTSTAMP;VALUE=DATE-TIME:20260419T043854Z UID:indico-contribution-2-2-30@ictp.it DESCRIPTION:Speakers: GIANONCELLI\, Alessandra (Elettra Sincrotrone Triest e)\n//indico.ictp.it/event/7638/session/2/contribution/30 LOCATION:Elettra Sincrotrone Trieste URL://indico.ictp.it/event/7638/session/2/contribution/30 END:VEVENT END:VCALENDAR
