HERCULES EUROPEAN SCHOOL is a five weeks course coordinated by the Université Grenoble Alpes (UGA). The school provides training for students, postdoctoral and senior scientists from European and non-European universities and laboratories, in the field of Neutrons, X-ray Synchrotron Radiation, and Free Electron Laser for condensed matter studies (Biology, Chemistry, Physics, Materials Science, Geosciences, Industrial applications). Neutron and X-ray science is integrated with complementary techniques like (but not only) optical and electron microscopy, NMR, optical and THz spectroscopy.
