摘要：

The choice of pulse repetition rates and pulse lengths provided by a pulsed neutron source cannot ideally fit the requirements of all of the various neutron scattering experiments. Novel multiplexing chopper systems we propose can help to enhance instrument performance by tailoring the effective pulse parameters to better meet experimental needs. In particular schemes to multiply pulse repetition rates and wavelength bands and to enhance wavelength resolution will be discussed, together with an efficient chopper system design tool based on the new concept of wavelength filtering.
