Development of Correlated Ion-Electron Sources (FIBback – WP1)
Significant progress has been made in advancing the FIBback system, which enhances ion beam performance through electron feedback control. Computational simulations, confirmed the feasibility of electron collection, a crucial component. As a result, new electrode designs have been finalized. This marks a critical step toward implementation, ensuring that future experiments can benefit from enhanced beam control. Additionally, an upcoming scientific publication will detail the extensive simulations performed to validate key aspects of this system. This work mainly involved PhD Students (Clelia Bastelica, paid by another contract, and soon Thomas Roy) and post-doc (Azer Trimeche)
High-Precision Ion Implantation System (IMPLANTION – WP2)
The project has also laid the groundwork for a universal high-precision ion implantation system. A theoretical study on femtosecond cesium ionization has started. Extensive simulation using Simion program have beed done validating all hypothesis done in the project to reach <10nm implantation. This work is mainly performed by Daniel Morvan as PhD Student.
Advancing High-Resolution Electron Energy Loss Microscopy (HREELM – WP3)
The HREELM setup has undergone a major upgrade to improve electron imaging capabilities. With: Replacement of the optical table to enhance experimental stability, Start of electrode design simulations, particularly for the time-of-flight analysis, Integration of a new electron gun (from Kimball physics) and sample holder (from UHV design) into the main chamber, setting the stage for the first experiments with pulsed electron sources. After all this the expriment is having a new start with the parallel design of the full machine by Kimball Physics and Electron Optica. This work is mainly performed by Florent Vallee as PhD Student and now also by Roba Moussaoui (post-doc paid by another contract especially to work with th Timepix detectors)
