Second dataset on diffraction patterns of electron vortex beams generated by the electrostatic chopstic/MINEON device- CL340

Franhofer diffraction dataset of electron vortex beams (EVBs) generated by the chopstic/MINEON device observed with a Camera Length of 340m on the K2 camera of the Titan Holo present in the Ernst-Ruska Centre at FZ-Julich. In this dataset, which can be accessed through Digital Micrograph and STEM_Cell it is possible to observe how by changing the potential difference between the two tips (main electrodes of the device) the radius of the EVB increases. A striking feature is that the radius increases almost linearly with the Orbital Angular Momentum. The analisys of this dataset can be found.at <strong>https://arxiv2203.00477.org/abs/</strong>
