Long citations

  • Dr Lucas Rovige (Institut Polytechnique de Paris, France) for his Thesis “Optimization, stabilization and optical phase control of a high-repetition rate laser-wakefield accelerator“

Through chirped-pulse amplification, a sub-picosecond laser pulse creates in its wake, inside a plasma at atmosphere pressure, a periodic concentration of electrons travelling at close to the velocity of light in vacuum. Laser peak irradiance higher than 10 to the power 18 watts per square cm gives access to 100 GV/m-level axial field and realises the dream of a next generation of accelerators being compactified by a factor of 1000. The PhD work was in one of these few labs which have maintained a constant effort on the concept and the associated optics engineering. It used ultrashort laser pulses, down to 1.3 optical cycles, to generate MeV electrons for irradiation of biological samples. Many outputs from this 3-year experimental and numerical project deserve the “outstanding” label: an impressive stability of million consecutive laser shots during hours, for the first time carrier-envelope phase effects influencing the electron beam pointing, and the first proof-of-principle experiment measuring the survival rate of cancerous cells irradiated with a 1 Gy/s dose rate. Underlying these results is solid work to optimize a helium gas jet through fluid simulations and the laser irradiance via self-focusing through kinetic modelling to achieve eventually a beam divergence as low as 3 mrad and electron energies up to 8 MeV.

High praise recommendations pinpoint a quickly-achieved autonomy, an impressive scientific maturity of the student and an outstanding contribution that opens new perspectives in the wakefield accelerator field. This work is already recognized by 7 highly-cited papers in peer reviewed journals, 5 as first author in high-rated journals such as PRX and by 2 invited presentations at international conferences. With teaching experience at physics department of its institution and a postdoctoral researcher position obtained immediately at the University of California on laboratory astrophysics, showing his ability to work in other research domains, this brilliant and creative student is a worthy recipient of the European Physical Society PhD award.

  • Dr Baptiste Frei (École Polytechnique Fédérale de Lausanne (EPFL)) for his Thesis “A gyrokinetic moment model of the plasma boundary in fusion devices“

Baptise Frei’s PhD thesis has tackled the challenge of modelling meaningfully the plasma edge region of a magnetically confined plasma. The aim of his work was to determine a framework with the correct physics representation and reasonable computational costs, able to reproduce the plasma edge behaviour in a wide range of collisionality regimes. Baptiste “invented” a new approach to the modelling of the plasma edge region, where gyrokinetic (GK) approaches developed for the plasma core are not suitable, and nor is fluid modelling typically used for the modelling of the Scrape-Off Layer (SOL). This new modelling framework is called the “Gyro-Moment” (GM) approach. The derivation of this model from a self-consistent electromagnetic GK boundary model is based on a polynomial expansion of the distribution function. Baptiste’s supervisor highlights in his letter of support that the analytical abilities shown by Baptiste in the model development are outstanding.

Applying the GM approach to the description of plasma dynamics in a wide range of collisionalities led Baptiste to derive a linearisation of the GM hierarchy including the GK Coulomb collisional operator and obtain closed analytical expressions. He then developed from scratch a numerical code implementing the GM approach. This led to the study of collisional effects in key plasma edge regimes (ITG, TEM, GAMs, and zonal flow damping), and comparison of the results with other modelling based on simplified collision operators. His analysis showed that the GM approach can indeed describe the relevant physics, as well as capturing new effects related to the improved collision model. To conclude, the PhD work of Baptiste Frei is of outstanding quality, quantity, and novelty, providing a framework for the modelling and understanding of a crucial but not very well understood plasma region, the edge, that is key to fusion plasma performance.

  • Dr Toby Adkins (University of Oxford) for his Thesis “Electromagnetic instabilities and plasma turbulence driven by the electron-temperature gradient“

An understanding of the heat-transport properties of a magnetically confined plasma is crucial for the design of future power plants. This thesis contributes two key findings concerning this understanding.

One topic concerns magnetized, electrostatic turbulence with wavelengths much shorter than the thermal ion gyroradius. Dr. Adkins concluded that an important parameter, the radial flux of energy induced by these turbulent fluctuations, scales with the size of the domain in the direction parallel (not perpendicular) to the equilibrium magnetic field. The thesis demonstrates, numerically and analytically, that in this short-wavelength limit, it is the weak inhomogeneity along the direction of the magnetic field that determines the turbulence-induced heat flux. This is clearly different from previous widely-used assumptions, and can be important for studies of instabilities limiting the performance of tokamak reactors. The second topic concerns electromagnetic instabilities driven by a gradient in the electron temperature. This subject is directly relevant for fusion physics and is well-known and often studied. Still, Dr. Adkins has identified and described the importance of the novel thermo-Alfvénic (TAI) instability. He found that this instability can be the dominant source of turbulence-induced thermal losses when the electron temperature gradient is steep. Dr. Adkins has investigated the relationship between this instability and others such as the longer wavelength kinetic ballooning mode. The differences between the TAI and the phenomenology of other instabilities can be traced to small differences in the governing equations.

A common idea is that the largest scales are the most important in determining the saturated amplitudes to which fluctuations and the related turbulent transport grow, regardless of the particular regime being considered (electrostatic, electromagnetic etc). This thesis shows a clear and deep insight into plasma physics, using a firm command of both analytical and numerical tools. Dr. Adkins is a worthy recipient of the European Physical Society PhD award.

  • Dr Mathias Hoppe (Chalmers University of Technology, Sweden) for his Thesis “Runaway-electron model development and validation in tokamaks”

Modelling physical phenomena is often a difficult problem because various features appearing in experiments must be synthesized using a mathematical formulation which can be used also to predict new scenarios. The work described in the thesis by M Hoppe reflects this path; the implementation of two codes, SOFT (Synchrotron detecting Orbit Following Toolkit) and DREAM (Disruption Runaway Electron Analysis Model), which are useful for the interpretation of the dynamics of electron runaway generation and development in tokamaks. These codes have been made available to the scientific community for interpreting experimental data in various devices in Europe and the USA. The generation of runaway electrons is one of the origins of disruptions in tokamaks and can lead to uncontrolled loss of plasma confinement and damage to the fusion device. The thesis describes accurately the concrete set-up of measurements used for the characterization of the runaway electrons, involving detection of synchrotron radiation (in the visible to infrared spectral range) and bremsstrahlung (in the gamma-ray range). The important directional characteristic of the radiation emitted by relativistic electrons is that it is essentially directed along the velocity direction, and this results in a great simplification of the runaway electron signature. Synthetic diagnostics derived using simplifying assumptions (in particular in the SOFT code) have been developed, and reconstructed images of runaways generated in a tokamak plasma have been compared with images recorded in the Alcator C-Mod tokamak showing a certain level of accuracy in the comparison, and a strong dependence on the assumptions in the model, in particular the parametrisation of the electron distribution function. The work described in the thesis represents a realization of original conceptual tools that are expected to help the scientific community to improve its understanding of runaway electron physics, a very important topic for the development of fusion energy.

2024 Hannes Alfvén Prize

The 2024 EPS Hannes Alfvén Prize is jointly awarded to professor Tünde Fülöp (Chalmers University of Technology, Sweden) and professor Per Helander (Max Planck Institute for Plasma Physics, Greifswald, Germany) for outstanding contributions to theoretical plasma physics, yielding groundbreaking results that significantly impact the understanding and optimization of magnetically confined fusion plasmas.

Professors Tünde Fülöp and Per Helander have significantly advanced plasma theory through a number of fundamental contributions. Their research spans many topics including runaway electrons, kinetic instabilities and transport processes in magnetized plasmas. By pinpointing key physical mechanisms, they have catalyzed innovative developments in experimental devices for nuclear fusion applications.

Professor Tünde Fülöp has been a leader in the field of disruptions and relativistic “runaway” electrons associated with these events. She has systematically explored the physics of runaway electrons in tokamaks and beyond, and conducted unprecedented modelling efforts applicable to both existing experiments and future devices. As part of this endeavour, Professor Fülöp has investigated various facets of the problem, including runaway-electron-driven electromagnetic instabilities, the impact of different collision types, radiation reaction effects, and the role of partially ionized impurities on runaway electron dynamics. Additionally, she has evaluated and optimized disruption mitigation strategies involving external magnetic perturbations and massive material injection. Furthermore, Professor Fülöp has played a crucial role in overseeing the development of several open-source, state-of-the-art runaway modelling tools and synthetic diagnostics. These tools have gained widespread use in the scientific community, reflecting her commitment to advancing collective knowledge in the field.

Professor Per Helander has obtained seminal results in the theory of stellarator plasmas by systematically exploring the question of how the properties of magnetically confined plasmas depend on the geometry of the magnetic field. In most such plasmas, turbulent transport caused by micro-instabilities arising from plasma density and temperature gradients poses a significant challenge. Professor Helander foresaw a crucial development, the absence of the most important density-gradient-driven instability in certain types of magnetic fields. This prediction is believed to underpin the remarkable record plasma performance achieved in the Wendelstein 7-X stellarator. In addressing long-standing concerns about neoclassical impurity accumulation in stellarators, professor Helander demonstrated a possible route to avoiding it in collisionality regimes relevant to reactors. Furthermore, he identified important differences between stellarators and tokamaks concerning plasma rotation. On large scales, it is relatively slow in stellarators and governed by neoclassical processes even in the presence of turbulent transport, and on small scales zonal flows behave differently. These and other revelations have shaped the general understanding of stellarator plasmas and the burgeoning field of stellarator optimization.
