Advanced Neutron Sources 1988, Proceedings of the 10th Meeting of the INT Collaboration on Advanced Neutron Sources (ICANS X), Held at Los Alamos, October 1988Revolving around the interaction between spectrometer and target-station design and performance, this volume emphasises the need for feedback that must exist between scientific requirements and source design. It achieves a forum for the sharing of information on the development of spallation neutron sources. Of great value to researchers in condensed matter physics, instrumentation and data processing involved in neutron scattering at pulsed and steady sources. |
