The Centre for Inertial Fusion Studies (CIFS)

Centre Directors: Professor Jeremy ChittendenProfessor Steve Rose

The Centre aims to provide a focus around which to develop the contributions of Imperial College and AWE scientists to Inertial Confinement Fusion and related High Energy Density Physics as well as exploring the use of Inertial Fusion for energy production.Since its inauguration in 2009, the CIFS has provided a mechanism for close collaboration between staff at Imperial College and their counterparts in AWE. The CIFS enables UK academia to benefit from the wide range of expertise in laser-plasma physics, computational modelling and high energy density physics available at AWE whilst also encouraging AWE staff to publicise their work and to participate in a broad range of international collaborations. The CIFS is also engaged in promoting the use of the Orion laser as a world class facility for fundamental scientific research through the Orion academic access programme

The Centre for Inertial Fusion Studies is jointly funded by AWE and Imperial College London.‌

Inertial Confinement Fusion and High Energy Density Physics facilities

As part of our research we collaborate with groups working on some of the largest experimental physics facilities in the world.
These include;

the National Ignition Facility,
a 2MJ laser based at Lawrence Livermore Laboratory, used for indirect drive ICF and fundamental HEDP research

the ZR generator,
a 24MA pulsed power generator laser based at Sandia National Laboratory, used for magnetic drive ICF and fundamental HEDP research

the Omega laser,
a 40KJ laser based at the University of Rochester, Laboratory for Laser Energetics, used for direct drive ICF and fundamental HEDP research

and the Orion laser facility,
a combined system of 10 long pulse and 2 peta-watt short pulse lasers used for defence science as well as academic research.

Academic Access on High Energy Density Physics facilities

Up to 15% of system time on the Orion laser is available to academic groups for fundamental scientific research. Details of the application procedure are on the Orion website.
The academic community has recently been invited to submit proposals for experiments to be performed on the LMJ/PETAL laser facility starting in 2017. Details of see the application process are available on the Intitut de Laser et Plasma website.
The SGII laser facility in Shanghai, also invites applications for fundamental science research from universities and institutes all over the world. Details of see the application process are available on the SIOM website. 

Recent News in ICF research

New Fusion Output Landmark at the National Ignition Facility

In 2017 the National Ignition Facility achieved its highest performance experiment, yielding 1.9x1016 neutrons (corresponding to 54kJ of fusion energy). This sees the fusion energy exceed the kinetic energy of the imploding shell for the first time. Nonetheless, large gains are still required for the fusion energy to exceed the energy put into the experiment by the 1.8MJ laser. The fuel self-heating is now thought to be larger than the heating from external sources, suggesting that the experiments are close to the 'ignition cliff', where small improvements in implosion quality can give large increases in performance. 

The recent improvements are largely down to a change in ablator material from plastic to high-density carbon, which allows more energy to be coupled from the laser to the capsule without increasing the damaging drive asymmetry. More information can be found in Sebastien Le Pape's June 2018 paper published in Physical Review Letters.

CIFS' Royal Society Summer Science exhibit 2014

Set the controls for the heart of the Sun

The SunScientists from the Centre for Inertial Fusion Studies exhibited their research at the Royal Society's Summer Science Exhibition 2014 in London. The exhibit was called Set the controls for the heart of the Sunand explained our work on recreating the conditions inside stars in the laboratory. The event provided the opportunity to meet, and informally chat with, scientists from CIFS, as well as from other cutting edge research projects around the UK.

What was the exhibit about?
Using one of the world’s newest and most powerful lasers, the Orion laser at AWE Aldermaston, researchers are close to being able to recreate the conditions inside the core of the Sun. A combination of laser pulses, lasting for just a fraction of a second, is fired at an area 10,000 times smaller than a pin-head, producing temperatures of millions of degrees at more than ten times the density of water. These conditions are getting closer to the conditions in the centre of the Sun, and many other stars in the Universe. The experiments help us understand how energy is transported around the Sun.
