摘要Bandwidth limiting neutron choppers are indispensable key equipments for the Lime-of-flight neutron scattering spectrometers of China Spoliation Neutron Source (CSNS). The main principle is to chop the neutron beam to limit the neutron wavelength bandwidth at the neutron detector. We have successfully developed a bandwidth limiting neutron chopper for CSNS in the CSNS advance research project II. The transmission rate of the neutron absorbing coating is less than 1 x 10(-4) (for 1 angstrom neutron). The phase control accuracy is +/- 0.084 degrees (+/- 9.4 mu s at 25 Hz). The dynamic balance grade is 01.0. Various experimental technical features have met the design requirements, and it also runs stably and reliably during the long-term tests. (C) 2015 Elsevier B.V.
