The feasibility of building an in situ high field polariser of 3He using the Metastability Exchange Optical Pumping (MEOP) technique is studying here. The first results obtained with different closed cells of 3He show the possibility to produce hyperpolarised gas up to 30% at 267 mbar and 67% at 32 mbar with a volume nagnetization production never obtained yet.
