Abstract: At neutron energies below about 3 meV, a disk chopper can produce shorter pulses than spallation-source cold moderators. The development of mica crystal-analyzer spectrometers at spallation sources has led to the use of energies well below 1 meV, where the shorter pulse of the disk chopper at a reactor cold-source can be exploited to build an instrument almost ten times shorter than its spallation-source counterpart. A short flight-path instrument has advantages for energy-range, total count-rate, and cost.
