First light detected at CoSAXS

First light detected at CoSAXS

 

On Thursday November 14, the team at the CoSAXS beamline detected the first monochromatic light, a crucial step in the beamline commissioning activities.

The CoSAXS beamline, set to become an advanced multipurpose Small Angle X-ray Scattering (SAXS) instrument, reached an critical landmark last week when the team detected the first monochromatic light. This detection proves that the first optical element, the monochromator, is functional.

The procedure took only five commissioning days from when the shutter was open to when the team saw the first monochromatic beam. “This is a remarkably fast execution” says Ann Terry, scientist at CoSAXS. “The short time needed to accomplish this step shows what a great job all the different support groups have done to allow us to reach this important milestone”.

The CoSAXS beamline team is already moving forward with the commissioning activities of the X-ray optics. This will lead to starting the commissioning in the experimental hutch in February 2020. First general users will be welcomed during Q4 2020.

Once in operation, CoSAXS will be a state-of-the-art beamline for Small Angle X-ray Scattering (SAXS), enabling researchers to use a variety of SAXS techniques and to take advantage of the inherent high coherent properties of MAX IV through X-ray Photon Correlation Spectroscopy (XPCS) experiments.
