DESCRIPTION:Speakers: CALLIGARO\, Thomas (C2RMF - AGLAE Laboratory\, Paris
 \, France)\nHeritage samples specificities (e.g. uniqueness\, fragility\, 
 complexity\, sensitivity to beam-induced modification)\nLarge artefacts\, 
 complex shape (positioning)\nOften cannot stand vacuum\nArtefact safety (h
 andling and damage risk reduction\, AIEA TM)\nMain addressed questions (e.
 g. provenancing\, manufacture\, preservation)\nWhich IBA techniques is sui
 table for each question\nPhoton-based: PIXE/PIGE/IBIL\nParticle-based: RBS
 /NRA/ERDA/SIMS\nIon imaging added value compared to classical imaging tech
 niques \nLimiting factors in external IBA imaging (SRIM simulations)\nProt
 ons and helium ions: probe size\nEnergy straggling\nReview of exit window 
 material and size\, and practically achieved resolution\nGas atmosphere (i
 mpact zone cooling)\nCharge monitoring\nMechanical scan\nLowering beam int
 ensity\nCurrent challenges\nIBA imaging of non-flat (3D) surfaces\nStereos
 copic view using multiple detectors\nGamma-ray and particle detectors acce
 ptance improvement\nUse of heavy ion beams (e.g. 19F and 15N beams for NRA
 )\n\n//indico.ictp.it/event/7638/session/0/contribution/2
