Accelerators: high energy physics, nuclear physics, healthcare, security,
energy, life science, novel materials, industry, …
Tens of millions of patients receive accelerator-based diagnoses and
treatment each year in hospitals and clinics around the world
All products that are processed, treated, or inspected by particle
beams have a collective annual value of more than $500B
The fraction of the Nobel prizes in Physics directly
connected to accelerators is about 30%

for the theoretical discovery of a mechanism that
contributes to our understanding of the origin of
mass of subatomic particles, and which recently
was confirmed through the discovery of the
predicted fundamental particle, by the ATLAS
and CMS experiments at CERN's Large
Hadron Collider

What is JAI
 The John Adams Institute for
Accelerator Science is a centre of
excellence in the UK for advanced
and novel accelerator technology,
created in 2004 to foster accelerator
R&D in the universities
 JAI is based on 3 universities:
University of Oxford and RHUL
initially, with Imperial College
joining JAI in 2011
 JAI scale: ~25 academic professorial
staff, ~15 research staff, ~10
affiliates, ~35 post-grad students,
~6-10 PhD/year in Acc. science
Sir John Adams (24 May 1920 - 3 March 1984) was the
'father' of the giant particle accelerators which have made
CERN the leader in the field of high energy physics. John
Adams worked at the UK Atomic Energy Research
establishment on design & construction of a 180 MeV
synchro-cyclotron. He then came to CERN in 1953 & was
appointed director of the PS division in 1954. In 1961-66
Adams worked as director of the UK Culham Fusion Lab. In
1971 he returned to CERN and served until 1975 as
Director-General of then called Laboratory II, responsible
for the design & construction of the SPS. From 1976-80 he
was executive DG of CERN and instrumental in approval of
LEP. John Adams was a foreign member of Russian
Academy of Science. On the photo above Adams
announcing that CERN just passed the Dubna’s
Synchrophasotron world record of 10GeV.

Simulation of laser-plasma acceleration
Rapid progress in beam energy achieved with laser-plasma acceleration shows
that the synergy of accelerators, laser and plasma is revolutionizing the field of
accelerator science
→ Compact X-ray light sources based on laser-plasma acceln
→ Aim to develop practical applications
Project developed in collaboration
with science centres in UK and worldwide
Laser Plasma accelerator
Modern synchrotrons (light sources) are big
machines (several 100s meters).
Similar electron energies can
be reached in a much more
compact accelerator using
the “wake” created by a
laser in a gas jet.
This could be used to build an accelerator compact
enough to fit in several tens of meters space but
powerful enough to be used as a light source (Free
Electron Laser).
Advanced light sources

and JAI on conventional and laserplasma based light sources

Laser plasma acceleration
For a student with an interest in synergy
of accelerator, laser and plasma science
To excite plasma oscillations: instead of a
single extremely high intensity laser pulse,
use a train of lower intensity pulses; works
theoretically, let’s try it experimentally!
If it works - tabletop lasers for plasma
accelerators, rather than national scale
facilities.

technology and accelerator science at JAI

Accelerator science is also attractive because…
• You will invent and will learn to do this efficiently, inspired by
history of great inventions in accelerators and by the nature itself

Accelerator science is also attractive because…
• Whether you are more inclined towards theory, or hardware
development, or simulations, there are tasks that will interest you
• Knowledge gained and developed has connections and applicable
