Chapman went to school at Elizabeth College, Guernsey. He graduated from Durham University (Hild Bede College) with an M.Sci. in Mathematics and Physics in 2004. [5]
Chapman then joined UKAEA's Culham laboratory as a plasma physics PhD student with Imperial College London. His research focused on understanding and controlling instabilities in the plasma fuel within tokamak fusion devices. He received his PhD in 2008. [6]
Chapman continued his plasma physics research at Culham and progressed through a number of positions in the UK fusion programme, including Head of Tokamak Science in 2014 and Fusion Programme Manager in 2015. In October 2016 he became UKAEA's Chief Executive Officer, succeeding Sir Steven Cowley. [7]
He has published over 110 journal papers and given 30 invited lead-author presentations at international conferences. In 2015, he became a visiting professor at Durham University. [8]
Chapman has held a number of international roles in fusion research. He was a Task Force Leader for the Joint European Torus fusion device from 2012 to 2014. He was appointed a member of the programme advisory committee for US experiment NSTX-U in 2013. He has chaired international working groups for the international fusion project ITER and led work packages within the EU fusion programme.
In April 2024, Chapman was appointed as non-executive director of the UK research funding agency, UKRI. [9]
Chapman's research has been recognised with a number of notable awards, including:
Chapman was knighted in the 2023 New Year Honours for services to global fusion energy. [16]
A tokamak is a device which uses a powerful magnetic field generated by external magnets to confine plasma in the shape of an axially-symmetrical torus. The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power. The tokamak concept is currently one of the leading candidates for a practical fusion reactor.
This timeline of nuclear fusion is an incomplete chronological summary of significant events in the study and use of nuclear fusion.
The Joint European Torus (JET) was a magnetically confined plasma physics experiment, located at Culham Centre for Fusion Energy in Oxfordshire, UK. Based on a tokamak design, the fusion research facility was a joint European project with the main purpose of opening the way to future nuclear fusion grid energy. At the time of its design JET was larger than any comparable machine.
The United Kingdom Atomic Energy Authority is a UK government research organisation responsible for the development of fusion energy. It is an executive non-departmental public body of the Department for Energy Security and Net Zero (DESNZ).
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.
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.
DEMO, or a demonstration power plant, refers to a proposed class of nuclear fusion experimental reactors that are intended to demonstrate the net production of electric power from nuclear fusion. Most of the ITER partners have plans for their own DEMO-class reactors. With the possible exception of the EU and Japan, there are no plans for international collaboration as there was with ITER.
ZETA, short for Zero Energy Thermonuclear Assembly, was a major experiment in the early history of fusion power research. Based on the pinch plasma confinement technique, and built at the Atomic Energy Research Establishment in the United Kingdom, ZETA was larger and more powerful than any fusion machine in the world at that time. Its goal was to produce large numbers of fusion reactions, although it was not large enough to produce net energy.
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.
EFDA has been followed by EUROfusion, which is a consortium of national fusion research institutes located in the European Union and Switzerland.
The Tokamak de Fontenay-aux-Roses, TFR for short, was the first French tokamak, built in a research centre of the French Atomic Energy Commission (CEA) in Fontenay-aux-Roses, a commune in the southwestern suburbs of Paris. The project was spearheaded by Paul-Henri Rebut, and is sometimes jokingly referred to as the "Tokamak façon Rebut".
Derek Charles Robinson FRS was a physicist who worked in the UK fusion power program for most of his professional career. Studying turbulence in the UK's ZETA reactor, he helped develop the reversed field pinch concept, an area of study to this day. He is best known for his role in taking a critical measurement on the T-3 device in the USSR in 1969 that established the tokamak as the primary magnetic fusion energy device to this day. He was also instrumental in the development of the spherical tokamak design though the construction of the START device, and its follow-on, MAST. Robinson was in charge of portions of the UK Atomic Energy Authority's fusion program from 1979 until he took over the entire program in 1996 before his death in 2002.
The Culham Centre for Fusion Energy (CCFE) is the UK's national laboratory for fusion research. It is located at the Culham Science Centre, near Culham, Oxfordshire, and is the site of the Joint European Torus (JET), Mega Ampere Spherical Tokamak (MAST) and the now closed Small Tight Aspect Ratio Tokamak (START).
COMPASS, short for Compact Assembly, is a compact tokamak fusion energy device originally completed at the Culham Science Centre in 1989, upgraded in 1992, and operated until 2002. It was designed as a flexible research facility dedicated mostly to plasma physics studies in circular and D-shaped plasmas.
Sir Steven Charles Cowley 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. Previously he served as president of Corpus Christi College, Oxford, since October 2016. and head of the EURATOM / CCFE Fusion Association and chief executive officer of the United Kingdom Atomic Energy Authority (UKAEA).
Ksenia Aleksandrovna Razumova is a Russian physicist. She graduated from the Physical Faculty of Moscow University in 1955 and took a position at the then called Kurchatov Institute of Atomic Energy in Moscow, then USSR. She defended her Ph.D. in 1966, was Candidate in Physical and Mathematical sciences in 1967, and became Doctor of Sciences in 1984. She is laboratory head at the Institute of Nuclear Fusion, Russian Research Centre Kurchatov Institute. Since the beginning she is actively involved plasma physics in research on the tokamak line of Magnetic confinement fusion.
Howard Wilson is a British professor of plasma physics at the University of York. He served as research programme director at the United Kingdom Atomic Energy Authority during 2017-2019, and then as interim Director of the STEP fusion reactor programme 2019-2020.
Tokamak Energy is a fusion power company based near Oxford in the United Kingdom, established in 2009. The company is pursuing the global deployment of commercial fusion energy in the 2030s through the combined development of spherical tokamaks with high temperature superconducting (HTS) magnets. It is also developing HTS magnet technology for other applications.
Spherical Tokamak for Energy Production (STEP) is a spherical tokamak fusion plant concept proposed by the United Kingdom Atomic Energy Authority (UKAEA) and funded by the UK government. The project is a proposed DEMO-class successor device to the ITER tokamak proof-of-concept of a fusion plant, the most advanced tokamak fusion reactor to date, which is scheduled to achieve a 'burning plasma' in 2035. STEP aims to produce net electricity from fusion on a timescale of 2040. Jacob Rees-Mogg, the UK Secretary of State for Business, Energy and Industrial Strategy, announced West Burton A power station in Nottinghamshire as its site on 3 October 2022 during the Conservative Party Conference. A coal-fired power station at the site ceased production a few days earlier. The reactor is planned to have a 100 MW electrical output and be tritium self-sufficient via fuel breeding.
