Abstract
We present here the stress evolution under thermal neutrons irradiation of NiC/Ti multilayers used in supermirror neutron guides. After irradiation, titanium undergoes a change of structure.
Stresses in nickel layers have been determined: it is shown that the evolution under irradiation depends on the deposition process.
6180H - Neutron effects.
6865 - Low dimensional structures: growth, structure and nonelectronic properties.
6112 - Neutron determination of structures.
