Postdoctoral Research Assistant in Electrodynamic manipulation of micron-sized particles
Department of Physics, Clarendon Laboratory, Oxford
A post is available at the Department of Physics, University of Oxford for a Post-Doctoral Research Associate (PDRA) to undertake experimental work in electrodynamic manipulation of micron-sized objects, managed by Prof. Foot. This project aims to develop methods to control both the orientation of non- spherical objects and their position in space, using a new electrodynamic apparatus to be designed and constructed. The workplan set out in the research proposal selected by the Leverhulme Trust covers a range of applications for this technique. Specific objectives include: (i) trapping metal foils a few microns thick by tens of microns wide for use as targets for high-repetition rate high-power laser systems, (ii) the electrostatic manipulation of graphene, carbon nanoribbons and other two-dimensional materials in a clean ultra-high vacuum environment for fabrication of novel devices as well as investigation of these materials at high temperatures via laser heating, (iii) measurement of the viscous drag of non-spherical particles, such as volcanic ash, held at different orientations, and (iv) biological samples may also be investigated, e.g., using an electrospray to create highly charged non-spherical objects. Developing methods to charge particles and capture them in an electrodynamic trap will be one of the main experimental tasks, especially in vacuum where there is no damping of the motion so that the electric fields need to be switched with precise timing.
The postholder will be expected to carry out practical work in the laboratory to investigate and develop these methodologies (taking measurements and analysing data), as well as collaborating with other PDRAs on technical aspects of the apparatus such as designing and constructing mechanical and electronic components. Prior experience with developing experimental control systems is not required since the primary role of the postholder to carry out experimental work in the laboratory and other members of the team are expert in the electronics etc. This project combines and extends ideas drawn from Physics, (Physical) Chemistry and (Electronic) Engineering and it is suitable for someone with a background in these, or related fields, who is open minded and willing to explore this new research direction. The Leverhulme Trust supports individual research projects with the vision to go beyond the fields traditionally supported by other funding bodies and with potential high rewards. It would also be desirable for the postholder to engage with potential end-users.
