was started with the goal of producing a cheaper and more efficient 3He polariser. In 1996, a first filling station for polarising 3He gas, nicknamed COW, was built at the ILL which used the metastabi ... filter on the D3 diffractometer. After several years of strong development of both the technique and the special bottle, this is a crucial ...

and H. Humblot (middle) working on the 3He polariser. A series of cells are filled with 0.7 mbar of pure 3He atoms. The discharge applied in the cells put the 3He atoms in a metastable state.

4-circle diffraction with a 3He dilution cryostat In the four-circle mode, the offset C-shaped Eulerian cradle can be equipped with a helium-flow cryostat (1.6 K to 450 K, or 0.1 K to 10 K in dilution

detector This very large banana PSD is of innovative design and works at high gas pressure (5 atm 3He + 1 atm CF4) for high efficiency coupled with high resolution (2.50 mm horizontally and 1.56 mm vertically;

One evening he asked Katie for a needle and some dark thread. He had come to France with only one pair of trousers, and this got a hole when working at the ILL-EDM.
