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.
New monochromator for I04. Big improvements, more to learn and deliver to users over coming months.
New remote access connection available
New BART robot installed on I04 - 37 pucks, 592 samples, 2.5x faster exchange times!
New focus options on I04. Variable beam size from 5 - 100 microns between 6 - 14 keV.

A new compound refractive lens focussing system has been implemented on the beamline since January 2015. This provides a variable focus beam size across the available energy range. The chart below shows fluxes for beam sizes at selected energies for the current beamline configuration:
From January 2013 until December 2014 repolished mirrors delivered a focussed beam of 90 x 40 µm across all available energies. When coupled with beam shaping apertures the photon fluxes obtained at the sample during this period are shown below:
