IµS 2.0 = IµS High Brilliance -

The high-end Incoatec microfocus X-ray source for unique efficiency and brightness

In 2011 - five years after the successful launch of the IμS - we introduced the next generation of Microfocus Sources: the Incoatec Microfocus Source IμS^{High Brilliance}!
Its outstanding performance raised the standard of low-maintenance sealed tube solutions for crystallography, available for Cu, Mo, Ag, Cr and Co radiation. Compared to the original IμS, the IμS^{High Brilliance} shows an increase in intensity of about 30 % for Cu, 50 % for Ag and 60 % for Mo. The IμS^{High Brilliance} perfectly matches the new Bruker AXS D8 crystallography solutions. In 2015, the 500th IμS was sold.

What´s different?
The improved heat-management makes it possible to produce more photons in the same small spot. Tried and trusted, our state-of-the-art Quazar multilayer optics are ideal for 2-dim focusing or collimating. Of course, the IμS^{High Brilliance} includes all familiar advantages of our previous IμS systems: air-cooling, no moving parts, long lifetime without maintenance and 3 years warranty.
Furthermore, memory chips are built into tube, tube mount and optics, recording the real-time status of the components (“DAVINCI” design). These data allow for easier installation and change of components, and can be accessed online, making remote diagnostics faster, better and easier. The result is an absolutely reliable system. The IμS fulfills highest safety standards: radiation safe, vacuum tested and fully compliant with Machinery Directive 2006/42/EC.

The comparison of the intensity of the original IμS and the IμS^{High Brilliance} shows an increase in intensity of about 30 % for Cu, 50 % for Ag and 60 % for Mo.

With a peak flux density of more than 2∙10⁹ photons/(s mm²) the Mo-IμS^{High Brilliance} enables scientists in small molecule and high-resolution crystallography to collect better data sets in shorter time. Measurements in the Incoatec AppLab with a Bruker D8 show an increase of more than 60 % in the diffracted intensity.
The compact design makes the IμS^{High Brilliance} an attractive component for many academic and industrial research organizations to upgrade existing X-ray analytical instruments to cutting-edge performance.
