The new Grenoble 100 microKelvin refrigerator, C. Bäuerle, Y. Bunkov, S.N. Fisher, Chr. Gianese and H. Godfrin, Proc. of the 21st. Int. Conf on Low Temp. Physics, Prague, August 8-14 1996, Czekoslovak J. of Phys. 46, suppl S5, 2791-2792, 1996. This machine was built by H. Godfrin and C. Gianèse. It is very long, because it was designed for NMR on 2D-3He samples. The demagnetization coil is far from the NMR coil, and the NMR field is very homogeneous. A Lancaster stage built by G.R. Pickett and S.N. Fisher was installed first, and used in “Cosmology experiments” (Kibble-Zurek effect), and particle detection (MacHe3 and ULTIMA projects). Later on, the Lancaster stage was replaced by a laminar copper stage made by Y.M. Bunkov and used for 3He/aerogel and 2D/3He studies.
