The 27th JCNS Laboratory Course on Neutron Scattering is a two-week program organized by the Jülich Centre for Neutron Science (JCNS) at Forschungszentrum Jülich, Germany, in collaboration with RWTH Aachen University. The course offers a unique opportunity for students and early-career researchers to gain theoretical knowledge and practical experience in neutron scattering. Week 1 focuses on lectures and exercises at Forschungszentrum Jülich, while Week 2 provides hands-on training at the Institut Laue-Langevin (ILL) in Grenoble, France. The course covers various neutron scattering techniques and includes free participation, accommodation, half-board meals, and travel reimbursement (up to 500€).
