# Category DIFFRN_RADIATION

Name:
`'diffrn_radiation'`

Description:

            Data items in the DIFFRN_RADIATION category describe
                   the radiation used for measuring diffraction intensities,
                   its collimation and monochromatization before the sample.

                   Post-sample treatment of the beam is described by data
                   items in the DIFFRN_DETECTOR category.

Examples:

Example 1 - based on PDB entry 5HVP and laboratory records for the structure corresponding to PDB entry 5HVP

        _diffrn_radiation.diffrn_id            'set1'

        _diffrn_radiation.collimation          '0.3 mm double pinhole'
        _diffrn_radiation.monochromator        'graphite'
        _diffrn_radiation.type                 'Cu K\a'
        _diffrn_radiation.wavelength_id         1

Example 2 - based on data set TOZ of Willis, Beckwith & Tozer [Acta Cryst. (1991), C47, 2276-2277].

        _diffrn_radiation.wavelength_id    1
        _diffrn_radiation.type             'Cu K\a'
        _diffrn_radiation.monochromator    'graphite'

Category groups:
`inclusive_group`
