Data-collection considerations
Schoenborn, B. P. and Knott, R.  International Tables for Crystallography (2012). Vol. F, Section 6.2.2.5, p. 174 [ doi:10.1107/97809553602060000819 ]
Data-collection considerations 6.2.2.5. Data-collection considerations Single-event-counting multiwire chambers with centroid-finding electronics (introduced in Section 6.2.1.4) are well suited for the type of time-sliced data collection that is mandatory for spallation neutron instruments. For large, high-resolution, multi-segmented detectors collecting about 100 time slices per ...

Time-of-flight techniques
Schoenborn, B. P. and Knott, R.  International Tables for Crystallography (2012). Vol. F, Section 6.2.2.4, p. 174 [ doi:10.1107/97809553602060000819 ]
Time-of-flight techniques 6.2.2.4. Time-of-flight techniques Because of the time structure inherent at a spallation source, diffraction experiments are carried out as a function of time and use a large part of the neutron energy spectrum. For protein crystallography, this wavelength range might cover from 1 to 5 ...

Beamline optics
Schoenborn, B. P. and Knott, R.  International Tables for Crystallography (2012). Vol. F, Section 6.2.2.3, pp. 173-174 [ doi:10.1107/97809553602060000819 ]
Beamline optics 6.2.2.3. Beamline optics A chosen wavelength band (say, 1 to 6) is selected by the use of rotating disks (called choppers) composed of neutron absorbing and transparent material. These choppers are synchronized to the proton pulse. The T0 chopper can open the beam a short time after the impact ...

Moderators
Schoenborn, B. P. and Knott, R.  International Tables for Crystallography (2012). Vol. F, Section 6.2.2.2, p. 173 [ doi:10.1107/97809553602060000819 ]
Moderators 6.2.2.2. Moderators Moderators for pulsed spallation neutron sources are nearly always composed of hydrogenous material of about 1l in volume. Either a thermal or fast reflector surrounds the moderator. Reflectors composed of materials with strong neutron slowing-down properties, such as Be or D2O, are called thermal reflectors; fast reflectors ...

Spallation neutron production
Schoenborn, B. P. and Knott, R.  International Tables for Crystallography (2012). Vol. F, Section 6.2.2.1, p. 173 [ doi:10.1107/97809553602060000819 ]
Spallation neutron production 6.2.2.1. Spallation neutron production Pulsed spallation neutrons are produced by protons generated by a particle accelerator (linac) with a frequency typically in the range 10 to 120Hz. The proton pulses are often shaped in compressor rings to shorten the pulses from the millisecond range to less than a ...

Spallation neutron sources
Schoenborn, B. P. and Knott, R.  International Tables for Crystallography (2012). Vol. F, Section 6.2.2, pp. 172-174 [ doi:10.1107/97809553602060000819 ]
