DESCRIPTION:Speakers: Mabuti Jacob Radebe Radebe (Necsa)\nDigital thermal 
 neutron imaging (radiography and tomography) is a powerful non-destructive
  analytical tool and has demonstrated its importance in industrial and res
 earch application world-wide.  However\, standards through test samples\, 
 methods and procedures\, which are essential when the technique is to be a
 pplied in the national and international industrial and research environme
 nt\, do not exist yet. Firstly\, characterization of the hardware faciliti
 es is essential in order to determine their capabilities in terms of beam 
 properties\, detection properties and subsequent combinations of the two s
 uch as spatial and temporal resolution\, acquisition period\, L/D\, S/N ra
 tio\, etc.  This can be achieved through the implementation of test sample
 s and test methods which entails the efforts towards achieving the correct
  test specimens\, procedures and practices. \nSecondly\, obtaining accurat
 e quantitative information from digital thermal neutron images is an impor
 tant development of this decade\, and establishment and finalization of st
 andardization in this regard is essential. A properly validated methodolog
 y to standardize quantitative digital thermal neutron imaging is of import
 ance in a number of current research fields of global interest which inclu
 des in-situ investigations of fuel cell dynamics as well as quantification
  in porous media. This presentation provides the layout of the proposal fo
 r the PhD study intended at contributing towards the establishment of nati
 onal and international standards for digital thermal neutron imaging. This
  entails a contribution towards the establishment\, evaluation\, validatio
 n and improvement of special test specimens as well as the creation and re
 finement of measurements\, procedures and practice utilizing digital neutr
 on radiographs and tomograms.\n\nhttps://events.saip.org.za/event/7/contri
