The next generation driving innovation in plasma accelerator science and technology
At the core of PACRI is a strong commitment to supporting and developing the next generation of scientists and engineers working in advanced accelerator technologies. Bringing together researchers from across Europe, the project provides an interdisciplinary environment where early career researchers (ECRs) can contribute to cutting-edge developments in plasma accelerators, RF systems, laser technologies, diagnostics, and related applications.
During the last PACRI Annual Meeting (March 2026) in Lisbon, young researchers had the opportunity to present their work, exchange ideas with experts across multiple disciplines, and strengthen collaborations within the wider European accelerator community. Their experiences highlight not only the scientific ambitions of PACRI, but also the importance of international collaboration, knowledge exchange, and training in shaping future research infrastructures.
Plasma-based acceleration technologies for medical applications
Working at the intersection of plasma physics, accelerator science, and biomedical applications, Diogo focuses on the development of plasma sources for compact electron acceleration. These plasma targets are essential components of wakefield acceleration schemes, which aim to provide more compact and cost-effective alternatives to conventional RF accelerators.
Particularly motivated by the medical potential of these technologies, his work explores how next-generation accelerators could contribute to applications such as advanced imaging techniques and radiotherapy.
Coming from a multidisciplinary background bridging biomedical sciences and physics, Diogo values the opportunity PACRI provides to connect fundamental research with real-world healthcare challenges.
“Being part of PACRI has reinforced my motivation to work at the intersection of physics and medicine, where fundamental research can directly contribute to transformative healthcare technologies.”
Reflecting on the wider PACRI community, he also emphasised the collaborative atmosphere of the project:
“My experience within the PACRI community has been both inspiring and formative. PACRI brings together highly motivated researchers who are eager to exchange ideas, challenge assumptions, and support one another’s work.”

Development of high-gradient X-band RF systems
Having entered the field of particle accelerators only a few years ago, Leo is now contributing to the development of high-efficiency X-band RF technologies and accelerating structures within PACRI.
His work involves the conditioning and characterisation of RF structures, integrating multiple high-performance systems including modulators, klystrons, low-level RF controls, diagnostics, and measurement setups. He enjoys the fact that the work is never limited to a single component; for example, he reckons understanding the behaviour of the full system is just as important as understanding each individual part. The research combines physics, engineering, and hands-on experimental problem solving in highly collaborative environments.
For Leo, one of the most valuable aspects of PACRI is the opportunity to work across disciplines and institutions while developing both technical and professional skills.
“What struck me most was the openness of the community and the chance to interact directly with researchers and experts from very different institutes and backgrounds.”
He added:
“For me, PACRI is not only a research project, but also an environment where I can grow quickly both professionally and personally. Working in such an international collaboration exposes me every day to new ideas, different approaches, and different ways of tackling complex problems.”
Beyond the technical work, PACRI has also provided experience in coordination, organisation, and large-scale international collaboration. Leo found out that- for someone at the beginning of their career, the combination of high-level research and a supportive environment is incredibly motivating.

Laser-plasma diagnostics and precision engineering
Supported through PACRI Work Package-14 activities, Slava is pursuing research at the interface of laser-plasma physics and precision engineering, contributing to developments for the future EuPRAXIA laser driver systems.
His work focuses on achieving extreme focal spot stability through the development of a novel diagnostic device capable of single-shot, real-time, spectrally resolved phase retrieval at high repetition rates. This technology represents a critical step toward implementing closed-loop wavefront correction in advanced laser systems.
The research directly supports the stability and precision requirements needed for next-generation laser-plasma accelerators and future compact research infrastructures.
“I am pursuing my passion for the intersection of laser plasma physics and precision engineering.”
Slava’s work highlights how PACRI enables young researchers to contribute directly to frontier technologies while developing specialised expertise in emerging accelerator concepts.
Building the Future of Sustainable Accelerator Science
Through projects such as PACRI, early career researchers gain access to international collaborations, advanced research infrastructures, and interdisciplinary training opportunities that extend far beyond a single field or institution.
By combining scientific excellence with collaboration across physics, engineering, computing, and industry, PACRI continues to support the development of the next generation of researchers who will help shape the future of sustainable, high-impact accelerator science in Europe and beyond.
Stay tuned for the next article in this meet-the-ECR series of ours.
