Multiple scattering in scanning helium microscopy
Description | The purpose of the award was to develop a new form of microscopy towards a commercially-viable instrument. The University of Glasgow contribution was to produce apertures and optical elements to form and focus the microscope's imaging illumination beam (of neutral helium atoms). This was achieved successfully and some results relating to this specific task are being written-up for publication. Development of the instrument itself has also been successful and has now been passed to an external company by my project partners at the University of Cambridge. Further details of the commercialisation can be found in their separate ResearchFish submission. |
Exploitation Route | The funding led to the development of a prototype instrument that is now available for use by external users and is actively being developed for commercial sale. The microscope technology may be employed in a wide variety of imaging applications, and particularly for sub-micron imaging of samples that have large-scale topographic features or that damage or electrostatically charge easily under examination by other microscopies. |

Title | Dataset supporting "Multiple scattering in scanning helium microscopy" |
Description | The data pack provides helium atom microscope image data for a test sample of FIB-ed trenches in silicon and of an Alvetex scaffold along with simulated ray tracing images for the same test sample. Optical profiler and SEM images are also provided that were used to measure the depth of the trenches. Text description files are included within the archive. The research was supported by EPSRC grants EP/R008272/1 and EP/R008051/1, as well as a Mathworks Ltd. studentship and a Leverhulm visiting professorship. |

Results and Impact | Invited talk at the biennial Microscopy and Microanalysis Congress (MMC), held online in July 2021. The congress typically attracts over 1000 delegates and the session in which I delivered my talk reached > 200 delegates. The talk, entitled "Improved thermoelectric design through multi-lengthscale structural analysis" was in the general area of energy materials and disseminated results of funded research, including the development of new nanoanalytical methodologies that have now been adopted by researchers elsewhere. |
