Third dataset on diffraction patterns of electron vortex beams generated by the electrostatic chopstic/MINEON device- CL23

Franhofer diffraction dataset of electron vortex beams (EVBs) generated by the chopstic/MINEON device observed with a Camera Length of 23m 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 https://arxiv.org/abs/2203.00477本数据集为搭载于德国于利希研究中心（Forschungszentrum Jülich, FZ-Julich）恩斯特·鲁斯克中心（Ernst-Ruska Centre）的Titan Holo设备的K2相机上，以23米的相机长度（Camera Length）观测得到的、由chopstic/MINEON装置产生的电子涡旋束（electron vortex beams, EVBs）的夫琅禾费衍射数据集。本数据集可通过Digital Micrograph与STEM_Cell获取，从中可观测到：当改变该装置的两个针尖（主电极）之间的电势差时，电子涡旋束的束半径会随之增大。该数据集的一个显著特征是，束半径几乎随轨道角动量（Orbital Angular Momentum）呈线性增长。针对本数据集的相关分析可参见https://arxiv.org/abs/2203.00477
