摘要：

The IN500 projects lakes advantage of three novel techniques to achieve a more than an order of magnitude gain in beam intensity delivered onto the sample at equal resolution compared to the best existing cold neutron TOF spectrometers: ta) the newly installed high intensity, long pulse coupled moderator at the Lujan center short pulse spallation source facility, (bl the recently proposed repetition rate multiplication trick to improve data collection efficiency and (c) the reduction of beam losses in long neutron guides by using a novel, "ballistic" design.
