SWIFT: proposal for a new, fast-scanning XAS beamline for operando studies on Diamond-II – Webinar

When: 17th of September and 4th of November
Where: Virtual

Following consultation with the User community in 2018, Diamond Light Source (Diamond) are proposing to build a new Flagship beamline dedicated to X-ray Absorption Spectroscopy as part of the Diamond-II upgrade program.  The new beamline, called SWIFT (Spectroscopy WithIn Fast Timescales), will be a high flux beamline optimized for the study of samples under operando conditions, and with the added potential to investigate sample heterogeneities at the 20 μm scale. The beamline will exceed the capabilities of the other XAS beamlines at Diamond for experiments that require an element of time resolution in dilute samples, and will bridge the existing spatial resolution gap between I18 and B18. It is expected that SWIFT will serve a very broad scientific community and that it will also significantly enhance Diamond’s capabilities for industrially relevant X-ray spectroscopy. Diamond firmly believe that this beamline proposal thus offers an exciting and transformational change for our community.

Diamond are proposing to build the new beamline on one of the newly available insertion device ports, using a multi-pole wiggler as the source. This new source will provide a significant improvement in flux over B18, and will consequently allow the investigation of faster processes in more dilute samples (fluorescence detection mode on the millisecond time regime), while keeping the efficiency of the continuous energy scans which have been proven very successful.  An additional end-station providing a smaller focal spot is also proposed for the beamline, to allow SWIFT to perform spatially resolved studies of heterogeneous systems. It is anticipated that the scope of this project will also include, from day one, appropriate experimental infrastructure, to support complex environments and experimental conditions. 

SWIFT will offer these new capabilities and will also provide much-needed extra capacity to our community, easing the demand on B18, systematically oversubscribed by more than a factor of 3 and amongst the three most productive physical sciences beamlines at Diamond.

The outline proposal was presented to a joint SAC/DISCo meeting last May, and they recommended that a full case should be put together for the instrument. A User Working Group has been set up with representatives of the User Community and will be responsible for developing the case to be considered for prioritisation by SAC/DISCo at the meeting that will take place on the 10th and 11th of December. 

This will be one of the few chances in the coming years to influence the construction of a new beamline at Diamond and therefore Diamond need to make the strongest case possible from the broad UK scientific community. To develop the proposal in an effective manner they now need your input on the exciting science and engineering that you would like to do using such an instrument, and also about the facilities that you believe will be required to deliver its programme.  

In order for Diamond to get the input they need, they have organised two Webinars (17th of September and 4th of November) with the aim of collecting your views and suggestions in an open discussion. Please sign up for the SWIFT Flagship Interest Group (registration form here) and attend the Webinar on the 17th of September at 9:30 am, where they will go through the beamline capabilities in detail and get your initial input.
