Hyperpolarisation of 3He at low/moderate magnetic field
M2 internship (2021/2022): Probing nuclear spin self-orientation in 3He gas discharges (Position is closed)
M2 internship (2021/2022) / Opening for PhD: Come and join the team for various investigations of polarisation dynamics in He gas discharges at low and moderate magnetic fields. Type of work: Experimental, numerical, theoretical.
More about context and topic
Low field MRI - Polarised helium-3
Please have a look at this poster (top part).
M2 position : Open
Skilled and motivated students are welcome to join our investigations on low field MRI with laser-polarised ³He gas or thermally-polarised water samples. Work may focus on the impact of concomitant field gradients on image quality. Another objective may be to investigate the short-pulse limit and revisit the Bloch-Siegert effect in pulsed NMR. (This topic is open for PhD.). Please contact us for more information.
Polarised helium - Liquid NMR
Skilled and motivated students are welcome to join the team for follow-up of our investigations on liquid NMR in laser polarised ³He-⁴He dilute solutions. Work will deal with the latest observations of non linear NMR dynamics and will focus on the comparison between experimental and numerical data. This topic is not open for PhD this year.
We are always looking for brillant motivated scientists to join our group.
Check the open positions (see above) or send us your CV for application.
