POLI: Polarised hot neutron diffractometer

Abstract

POLI, which is operated by the Institute of Crystallography, RWTH Aachen University in cooperation with JCNS, Forschungszentrum Jülich, is a versatile two axes single crystal diffractometer with broad field of applications. Mostly dedicated to the investigation of magnetic structures in single crystals using neutron spin polarisation, POLI is also used for classical structural investigations under extreme conditions. High intensity hot neutrons flux makes it attractive also for the other applications like study of parity violations phenomena in nuclear physics or BNCT (boron neutron-capture therapy) in medicine.
