I04 is one of five macromolecular crystallography beamlines at Diamond. The typical working wavelength is 0.9795 Å (12.658 keV) but it is tuneable over the wavelength range 0.69 - 2.066 Å.

The beamsize can be focussed from 10 x 5 to 110 x 100 microns across the available energy range.

All MX beamlines use SPINE standard pins and Unipucks from cryocooled samples. The beamline can be accessed remotely.
