Monochromator Equipment Analysis of Neutron Triple-Axis Spectrometer(In Chinese)

Monochromator is one of the most important parts of neutron Triple-Axis Spectrometer(TAS),and its performance has an effect on data detecting and analyzing.We have investigated some monochromator parameters of neutron TAS in China,ILL and LLB.Because there is different location and focus on wavelength in experiment,appropriate neutron source and location limit should be taken into account in the design of monochromator.According to the basic principle of the focusing monochromator,investigation and analysis of typical monochromator in the world,including size,crystal,research capability,we can offer references on the type and parameters for the construction of tripleaxis spectrometer monochromator.
