Cross fire
Arndt, U. W.  International Tables for Crystallography (2012). Vol. F, Section 6.1.3.5, p. 163 [ doi:10.1107/97809553602060000818 ]
Cross fire 6.1.3.5. Cross fire The cross fire is defined as the angle or the half-angle between extreme rays in the beam incident on a given point of the sample. In the absence of focusing elements, such as specularly reflecting mirrors, the X-ray beam diverges from the source. A ...

Intensity
Arndt, U. W.  International Tables for Crystallography (2012). Vol. F, Section 6.1.3.4, p. 163 [ doi:10.1107/97809553602060000818 ]
Intensity 6.1.3.4. Intensity The intensity of the primary X-ray beam should be such as to allow data collection in a reasonably short time; increased speed is one of the main factors which has led to the popularity of synchrotron-radiation data collection as compared to data collection using conventional sources. ...

Properties of the X-ray beam
Arndt, U. W.  International Tables for Crystallography (2012). Vol. F, Section 6.1.3, pp. 162-164 [ doi:10.1107/97809553602060000818 ]

X-ray wavelength
Arndt, U. W.  International Tables for Crystallography (2012). Vol. F, Section 6.1.3.2, p. 162 [ doi:10.1107/97809553602060000818 ]
X-ray wavelength 6.1.3.2. X-ray wavelength For X-ray tube sources, the main component of the beam is the characteristic radiation of the tube target. The vast majority of macromolecular structure determinations have been carried out with copper K[alpha] X-rays of wavelength 1.54. These are reasonably well ...

Beam size
Arndt, U. W.  International Tables for Crystallography (2012). Vol. F, Section 6.1.3.1, p. 162 [ doi:10.1107/97809553602060000818 ]
Beam size 6.1.3.1. Beam size The best signal-to-noise ratio in the diffraction pattern is secured when the sample crystal is just bathed in the X-ray beam, which is often taken to be about 0.2 to 0.3mm in diameter. Unfortunately, many crystals are plate- or needle-shaped and present ...

Spectral composition
Arndt, U. W.  International Tables for Crystallography (2012). Vol. F, Section 6.1.3.3, pp. 162-163 [ doi:10.1107/97809553602060000818 ]
Spectral composition 6.1.3.3. Spectral composition Any X-rays outside the wavelength band used for generating the desired X-ray pattern contribute to the radiation damage of the sample and to the X-ray background. In the interests of resolving neighbouring diffraction spots in the pattern, one would require the wavelength spread ...
