Diamond-II Webinar: VerSoX Beamline Upgrade Proposal

Nov 05. till Nov 05.

Diamond-II Webinar: VerSoX Beamline Upgrade Proposal

This webinar is your opportunity to gain insight into the Structures and Surfaces Group's flagship beamline upgrade proposal for VerSoX: An undulator source for Ambient Pressure XPS. This proposal forms part of the science case for Diamond-II, a co-ordinated programme of development that includes a major machine upgrade.

A user working group has been convened to prepare a full proposal for presentation at the December SAC/Disco meeting. As part of the proposal preparation, we would like to hear from the user community. Please join us for this webinar which will present the current draft of the proposal produced by the user working group and give opportunities to ask questions and provide further input for the document.

Please find the proposal background and agenda below, along with the link to download the webinar as a calendar appointment with the Zoom details.

Proposal Background

A substantial upgrade to the VerSoX beamline as part of the Diamond-II project is proposed, taking advantage of the potential to create ‘mid-straight’ sections that allow the current bending magnet beamlines to be sourced by insertion devices. The current VerSoX beamline (B07) has two end stations that can operate simultaneously, one for Ambient Pressure X-ray photoelectron spectroscopy (AP-XPS) and the other for high throughput NEXAFS/UHV-XPS. It achieves this by each branch taking a portion of the X-rays from the current bending magnet source. AP-XPS is a flux hungry technique and the proposed upgrade would increase the flux for the measurements by typically a factor of 80x together with a smaller spot size; enabling measurements at higher energies (more penetrating) and therefore at higher pressures or for solid-liquid interfaces. In addition, the undulator source provides tuneable linear and circular polarization enabling new types of experiments on the beamline. These developments will enable studies of materials relevant to catalysis, metal-organic interfaces, biomaterials, oxide growth, battery interfaces, lubrication and nanoparticle studies amongst many others.

This webinar forms part of the second stage of user engagement for the Structure and Surfaces Group's proposals. In 2018, an introductory workshop was held for users to discuss the project's potential benefits for research and to help further develop the science case and direction for the machine upgrade. You can revisit the event page here.
