Phases and texture via X-ray diffraction in neutron optics multilayers

(Ref. SON_1)

 

This internship will take place within the Multilayers group of the ILL’s Neutron Optics Service. The group produces neutron optical devices based on metal multilayer super-mirrors, in particular Ni/Ti and Fe/Si, deposited by magnetron sputtering (PVD). Although the optical performance of these mirrors has been accurately assessed, their microstructure is not always well known: phases distribution, texture, micro-strains, etc. The aim of the internship is to start to analyse these aspects by using X-ray diffraction, in order to estimate their dependence on the coating parameters. A first approach will be possible using the X-ray instruments available at the ILL, then the access to more dedicated instruments outside the ILL will be considered.

 

Activities of the trainee:

- Preparation of an experimental plan from the many samples available.

- First measurements and analyses with the diffractometers accessible at the ILL.

- More precise determination of the instrumental requirements, and contacting of external teams in order to perform measurements (X-ray characterisation platforms).

- Analysis and interpretation of the results ("MAUD" software).

 

Level required:

5th year university studies in physics of materials

 

Language skills:

As an international research centre, we are particularly keen to ensure that we also attract applicants from outside France. You must be able to communicate in English or in French.

 

Notes:

This post is an internship with a duration of a minimum of 5 months

 

 

Benefits:

You will receive a monthly allowance of between 750 € and 900 €, depending on the duration of your internship and your profile.
