Project description:
This aim of this project is to develop and implement a completely new microscopy method, magnetic beam imaging, a method which will be capable of imaging the surface of delicate specimens which cannot be studied using existing microscopes. In recent years extensive efforts have been made to develop neutral helium microscopes which can image specimens without causing damage or perturbing the surface[1]. The spatial resolution in existing neutral beam microscopes is severely limited with respect to some other microscopes. In this project an alternative neutral-beam microscopy method will be developed. The new approach is based on magnetic manipulation methods, developed in our group in the last few years [2], which use magnetic fields to control the spin-rotational quantum states of atoms/molecules. These manipulation methods are currently used to study the interaction of molecules with surfaces, but will be modified and adapted to produce spatial resolution images of the specimen the beam interacts with. The imaging method, which will be tested for the first time in this project, is expected to significantly surpass the resolution and measurement time restriction of existing neutral beam microscopes, and potentially provide new contrast mechanisms related to the magnetic properties of the surface.
