Coulomb Interactions in Particle Beams

Guus Jansen earned both his MSc (1983) and PhD (1988) in Physics from Delft University of Technology, graduating Cum Laude for both degrees. His PhD thesis on "Coulomb Interactions in Particle Beams" won the prestigious Shell Award for the best research project at Delft in 1988. This work was first published by Academic Press in 1990 in the series Advances in Electronics and Electron Physics and is being republished in 2024 in Advances in Electronics and Imaging Physics. From 1983 to 1985, his first role after earning his MSc was as a postdoctoral researcher at IBM's General Technology Division in New York, focusing on variable-shaped beam electron lithography. After his PhD, he served as a research physicist at the Royal Dutch/Shell Laboratories in Amsterdam (1989-1992), where he led the development and modeling of refinery equipment and chemical processes. In 1992, he transitioned into strategic consulting as a Senior Management Consultant at Monitor Company (1992-1996), advising top-tier corporations across a range of industries. In 1996, he joined Telfort, a joint venture between British Telecom and Dutch Railways (NS), as Director of Marketing & Business Development. As a member of the board, he oversaw corporate strategy, business planning and development, product development, and management. Since 2000, Guus has operated as a serial entrepreneur through Caneval Ventures, his business development and investment company. Caneval Ventures has initiated, supported, and led multiple startups and scale-ups in the ICT and renewable energy sectors, with Guus serving as CEO, CCO, and CFO of various companies. In 2002, Caneval Ventures acquired the IP rights for MonTec and Interac software, both of which were initially developed as part of Guus' PhD research. These software packages have been adopted by leading companies like IBM, Toshiba, Philips, and several universities and research institutions globally. Over the years, Caneval Ventures has provided consultancy to various institutions and companies, specializing in quantifying and mitigating the effects of Coulomb interactions in charged particle systems.
