Sir Steven Charles Cowley FRS FREng FInstP (born 1959) is a British theoretical physicist and international authority on nuclear fusion and astrophysical plasmas. He has served as director of the United States Department of Energy (DOE) Princeton Plasma Physics Laboratory (PPPL) since 1 July 2018. [5] Previously he served as president of Corpus Christi College, Oxford, since October 2016. [6] and head of the EURATOM / CCFE Fusion Association and chief executive officer of the United Kingdom Atomic Energy Authority (UKAEA). [6]

Contents

Education

Cowley won a scholarship to Corpus Christi College, Oxford and graduated with a Bachelor of Arts degree in Physics in 1981. [6] He went on to study at Princeton University as a Harkness Fellow and was awarded a PhD in 1985 for research into tokamaks supervised by Russell Kulsrud. [4] [7] [8] [9]

Career and research

Following his PhD, Cowley completed postdoctoral research at the Culham Centre for Fusion Energy (CCFE). He returned to Princeton in 1987 and joined the faculty at University of California, Los Angeles (UCLA), in 1993, becoming full professor in 2000. At Imperial College, London, Cowley led the plasma physics group from 2001 to 2003, while also serving as a part-time professor. [10] [11] He was appointed as the head of the EURATOM / CCFE Fusion Association in September 2008 and as CEO of UKAEA in November 2009.

On 18 March 2015, he was elected the 31st President of Corpus Christi College, Oxford, his alma mater: he took up the post on 1 October 2016. He is the first scientist to hold the post. [12]

On 1 July 2018, he was appointed director of the Princeton Plasma Physics Laboratory (PPPL). [13]

Cowley's research interests are in plasmas and nuclear fusion, in astrophysical plasmas and the laboratory, such as the Joint European Torus (JET) and the International Thermonuclear Experimental Reactor (ITER). [3] [14] [15] [16] [17] [18] [19] [20] [21] His research has been funded by Science and Technology Facilities Council (STFC) and the Engineering and Physical Sciences Research Council (EPSRC). [22] [23] Cowley co-chaired the National Academy of Sciences assessment of plasma science in the United States. [24] [25] [26]

Awards and honours

Cowley was elected a Fellow of the Royal Society (FRS) in 2014. His biography reads;

Steven Cowley is a leading plasma theorist and currently chief executive officer at the UK Atomic Energy Authority. Much of his research career has been devoted to modelling and understanding plasma turbulence in nuclear fusion, a phenomenon that must be controlled to achieve stable fusion.

Nuclear fusion will offer future generations a cleaner and safer source of energy and has the potential to meet the majority of the world's energy demands. At present, however, more energy is required to feed the process than can be produced. Steven is leading the UK's participation in ITER, an experimental reactor that is set to make nuclear fusion commercially viable.

Steven's interest in plasmas extends to those found on a large scale throughout the Universe. He showed that these astrophysical plasmas also invariably exhibit turbulence, which amplifies and shapes their magnetic fields. Steven presented a 2009 TED talk entitled Fusion is Energy's Future and received the 2012 Glazebrook Medal from the Institute of Physics, which rewards leadership in a physics context. [27]

His certificate of election reads:

Professor Cowley is currently chief executive officer at the UK Atomic Energy Authority and Professor at Imperial College. Over the last twenty years he has played a leading role in developing the multi-scale approach to computing the plasma turbulence in fusion experiments. Now such computations routinely reproduce experimental results. Multi-scale computational tools will be central to the successful development of fusion power. He discovered a key mechanism for the observed explosive eruptions from confined plasmas. Using analysis and computations Cowley and collaborators have shown that astrophysical plasmas are invariably turbulent. They have described the multi-scale spectra and structure of this turbulence and how it amplifies and shapes the magnetic field in the large scale plasmas of the universe. [28]

Cowley was also elected a Fellow of the American Physical Society (APS) in 1998, [29] the Institute of Physics (FInstP) in 2004 [30] and the Royal Academy of Engineering (FREng) in 2014. [31] He was awarded and honorary fellowship of the Institute of Engineering and Technology in 2015. In 2011, he was appointed to the UK Government's Council for Science and Technology. [32]

In the 2018 Birthday Honours, Cowley was appointed a Knight Bachelor for services to science and to the development of nuclear fusion. [33] In July 2019, Cowley was awarded the honorary degree of Doctor of Science (honoris causa) by the University of Lancaster for his standing as the international authority on fusion energy. [34]

Princeton Plasma Physics Laboratory (PPPL) is a United States Department of Energy national laboratory for plasma physics and nuclear fusion science. Its primary mission is research into and development of fusion as an energy source. It is known for the development of the stellarator and tokamak designs, along with numerous fundamental advances in plasma physics and the exploration of many other plasma confinement concepts.

<span class="mw-page-title-main">Plasma stability</span> Degree to which disturbing a plasma system at equilibrium will destabilize it

In plasma physics, plasma stability concerns the stability properties of a plasma in equilibrium and its behavior under small perturbations. The stability of the system determines if the perturbations will grow, oscillate, or be damped out. It is an important consideration in topics such as nuclear fusion and astrophysical plasma.

Magnetic confinement fusion (MCF) is an approach to generate thermonuclear fusion power that uses magnetic fields to confine fusion fuel in the form of a plasma. Magnetic confinement is one of two major branches of controlled fusion research, along with inertial confinement fusion.

<span class="mw-page-title-main">Mega Ampere Spherical Tokamak</span> UK experimental fusion power reactor

Mega Ampere Spherical Tokamak (MAST) was a nuclear fusion experiment, testing a spherical tokamak nuclear fusion reactor, and commissioned by EURATOM/UKAEA. The original MAST experiment took place at the Culham Centre for Fusion Energy, Oxfordshire, England from December 1999 to September 2013. A successor experiment called MAST Upgrade began operation in 2020.

Rendel Sebastian "Bas" Pease FRS was a British physicist who strongly opposed nuclear weapons while advocating the use of nuclear fusion as a clean source of power.

An edge-localized mode (ELM) is a plasma instability occurring in the edge region of a tokamak plasma due to periodic relaxations of the edge transport barrier in high-confinement mode. Each ELM burst is associated with expulsion of particles and energy from the confined plasma into the scrape-off layer. This phenomenon was first observed in the ASDEX tokamak in 1981. Diamagnetic effects in the model equations expand the size of the parameter space in which solutions of repeated sawteeth can be recovered compared to a resistive MHD model. An ELM can expel up to 20 percent of the reactor's energy.

The ballooning instability is a type of internal pressure-driven plasma instability usually seen in tokamak fusion power reactors or in space plasmas. It is important in fusion research as it determines a set of criteria for the maximum achievable plasma beta. The name refers to the shape and action of the instability, which acts like the elongations formed in a long balloon when it is squeezed. In literature, the structure of these elongations are commonly referred to as 'fingers'.
