Very Intense Polarized (VIP) neutron diffractometer at the ORPHEE reactor in Saclay

A new polarized neutron diffractometer has been commissioned at the ORPHEE reactor in Saclay. Hot neutron beam of 0.8 angstrom is obtained by Heussler monochromator. 64 position sensitive detectors cover angular range of 25 degrees x80 degrees in vertical and hoiizontal directions, which allows performing measurements of flipping ratios for dozens of reflections simultaneously. Data acquisition and data treatment programs have been developed. Possibilities of multi-crystal experiments and studies of powder samples have been tested. Ensemble of these measures should boost the data acquisition rate of magnetization densities by a factor of 5-20 depending on the crystal cell parameters. (C) 2013 The Authors.
