Neutron Imaging in research and Industry

Yves Bréchet HC Atomic Energy

ILL, CRISP workshop, 17th marsh 2014

SLIDE 2

Assets (1)

Grenoble speciality ( both neutrons and X rays

large instruments)

Direct space

 direct interpretation  direct artefacts

Mesoscale: 10mm and above

 Natural scales Man made structures Scale of damage events

SLIDE 3

SLIDE 4

Asset (2)

Deep penetration

Non destructive analysis Long range interation phenomena ( elastic stresses)

Sensitive to light elements

SLIDE 5

Who may be interested?

Anybody interested in the elements with the

largest cross section such as Li, H2, Cl…

Fuel cells, batteries…

Any body with events at the mesoscale

=>cracks, voids, methanisation…

Anybody interested in fuid motion in situ

=> microfluidics, heat exchangers

SLIDE 6

Fuel Cell

SLIDE 7

Li Batteries

SLIDE 8

Fuel injection in an explosion engine: dynamic neutron imaging

SLIDE 9

C. Gruenzweig et al. (PSI)

Visualizing Soot and Ash in Diesel Particulate Filters

SLIDE 10

Soot sediments in vent pipe of air plane engine (accident investigation)

I. Manke et al. (HZB)

SLIDE 11

Hybrid and architectured materials

X-Rays Neutrons

SLIDE 12

If you could go to a better resolution…around 1mm

Cavity nucleation in creep
Hydrides formation under stress in Zr
Fluid flow and boiling crisis
Cavitation process in diesel
Foamings of polymers and metals
Non destructive testing of glued assemblies
Distribution or organic and inorganic matter in

structural biomaterials
