We show here a few examples of the use of polarised 3 He cells on neutron spectrometers. Benoit Mestrallet placing a freshly polarised 3 He cell on D3, the Spin Polarised Hot Neutron Beam Facility. For ... transport from Tyrex-2 to the instrument, the cell is placed in a special transport container with the suitable magnetic field to maintain the ...

The cell membrane is a complex system, consisting of a semipermeable phospholipid bilayer embedded with various types of proteins, that controls the movement of substances in and out of a cell. Understanding ... their hydrogenous and deuterated form, were then used to make advanced, more biologically relevant cell membrane models. The ...

depolarisation time T1. The main relaxation contributions typically arise from the material of the NSF cells and magnetic field gradients. Relaxation times are currently of the order of 100-300 hours, which ... exchange optical pumping for polarising the 3 He gas at about 1 mbar pressure in ten optical pumping cells. The gas is then compressed up ...

absorption (polarized 3 He). In the latter case, 3 He has to be polarised first and then placed in cells called "spin filters", hence Tyrex-2 . This approach provides very interesting properties: simple
