MACS –a New High Intensity Cold Neutron Spectrometer at NIST February 17, 2003Timothy D. Pike1 Developing MACS A Third Generation Cold Neutron Spectrometer

MACS –a New High Intensity Cold Neutron Spectrometer at NIST February 17, 2003Timothy D. Pike2 What is MACS? MACS is a Multi Axis Crystal Spectrometer that is under development at the NIST Center for Neutron Research. This third generation cold neutron spectrometer will provide ultra high sensitivity access to dynamic correlations in condensed matter on length scales from 0.1 nm to 50 nm and energy scales from 0.05 meV to 20 meV. The project is funded jointly by the NIST Center for Neutron Research, the National Science Foundation, and the Johns Hopkins University and will be complete in the fall of This talk will discuss the state of the design as a snapshot of the overall instrument development process. Professor Collin Broholm Johns Hopkins University
