Introduction to Modern Chopper Spectrometers for Pulsed Neutron Sources

Abstract

Introduction to the latest modern chopper spectrometers for pulsed neutron sources is shown. After coming up of recent high-performance pulsed neutron sources such as J-PARC, SNS and 2nd target station of ISIS, much progress have been achieved in technology regarding to chopper spectrometers in both hardware and software. A multi-E_i measurement based on repetition rate multiplication technique alters strategy of the measurements. Source pulse shaping provides opportunity precise measurements with high intensity. Current data analysis software enables us to access to the four dimensional space in energy and momentum transfers.
