Second prize winner of the 1^st ´Illustrating NMI3´ Picture Competition :

Sergey Klimko from Laboratoire Léon Brillouin for his photograph of a new spin –flipper for neutron resonance spin-echo (NRSE) spectrometer MUSES at LLB, CEA-Saclay.

New spin-flipper for neutron resonance spin-echo (NRSE) spectrometer MUSES at LLB, CEA-Saclay.

Spin-echo measurements with NRSE require a set of different values of static magnetic field and corresponding radio-frequency fields in spin-flipper. The present spin-flipper can provide a wide range of magnetic fields (from 0 to 300 G) and frequency range from 50kHz to 1 MHz. The high resolution of the MUSES spectrometer results from the homogeneity of the magnetic fields in the flippers.
