Title: Introduction to ISIS pulsed Neutron and Muon facility and simple science examples

Abstract：

The ISIS pulsed neutron and muon source at the Rutherford Appleton Laboratory in Oxfordshire UK is a world-leading centre for research in the physical and life sciences. ISIS produces beams of neutrons and muons that allow scientists to study materials at the atomic level using a suite of instruments, often described as ‘super-microscopes’. It supports a national and international community of more than 2000 scientists who use neutrons and muons for research in physics, chemistry, materials science, geology, engineering and biology. From the original vision over 30 years ago, ISIS has become one of the UK’s major scientific achievements. As the world’s leading pulsed neutron and muon source. ISIS has changed the way the world views neutron scattering and muon spin rotation and relaxation, which provide microscopic and fundamental information on the complex many body systems. I will briefly introduce the neutron and muon techniques and discussed the production of neutrons and muons at ISIS facility. I will discussed neutron and muon instruments, data analysis software and present some recent science examples. The science examples will be focussed on the investigations of spin excitations in Fe-based superconductors and heavy fermion superconductors, spin wave investigation in mutliferroics materials, spin gap and spin wave investigation in Kondo insulators and magnetic excitations in molecular magnets. Further, I will discuss investigations of novel crystal structure using the high resolution neutron powder diffraction and magnetic structures using a cold neutron diffractometer and diffuse scattering investigations using a single crystal diffractometer. I will also show how muon technique is used to investigate elemental analysis. I will also present upgrade plan for excitations instruments. Further I will show new funding mechanism for Chinese user community to use ISIS Facility.
