Colliders – explore what matter is made of 

The hottest spots in the galaxy 

When the two beams of protons 

collide, they will generate 

temperatures 

1000 million times hotter 

than the heart of the sun, 

but in a minuscule space

“Yesterday” 

LEP Collider, CERN 

SLAC Linear Collider 

“Today” 

VEP-2000 Collider, BINP 

Tevatron collider, Fermilab 


Precision measurements at CERN/LEP and 

SLAC/SLC establish Standard Model – explains 

how particles interact … 

But profound 

question remain 

• Why do the particles all 

have different masses, 

and where does the mass 

come from? 

What causes mass?? 

The mechanism – Higgs or 

alternative appears around 

the corner 


Composition of the universe 

Known and Understood 

Matter 

Unknown Matter ~ 90% 

DARK MATTER & 

DARK ENERGY 

What is Dark Matter ? 

• Perhaps a new form of elementary particle? 


Supersymmetry and Dark Matter 

• Just as with anti-matter, new particles are predicted 

• Supersymmetric particles have just the properties expected of 

Dark Matter 


Large Hadron Collider 

Proton beam stores 700 MegaJoules equivalent to Boeing 

747 energy on take-off – enough to melt 1/2 ton copper 



The Biggest Detectors ever built

LHC and e + e - Collider 

LHC will open the curtain 

of a theatre of new physics 

Proton is a composite object –

Electron and positron are zero-size 

objects

Accelerators can drive next-generation reactors 

that burn non-fissile fuel, such as thorium 

Dominant feature of ADSR – its inherent safety

materials such as graphene) have 

been studies by combination of 

neutron scattering and x-ray

October 5, 2010: 

Andre Geim and Konstantin Novoselov from the University of 

Manchester have been awarded this year's Nobel Prize in Physics 

following their pioneering research on Graphene 


Accelerators and Nobel 

Recent studies by Alexander W. Chao and Enzo F. Haussecker 

(SLAC) have shown that 

The fraction of the Nobel prizes in Physics directly 

connected to accelerators is very close to 30%

SRF Compact Light Sources @ 4K

– Too complex for a University or small institution-based accelerator 

– Cryogenics is a strong cost driver for compact SRF linacs 

• Spoke cavities can operate at lower frequency 

– Lower frequency allows operation at 4K 

– No sub-atmospheric cryogenic system

Crucial source for many advances in biology, medicine, solid state 

physics, future energy production, and various other fields 

Interdisciplinary research on the boundaries of accelerator, laser, 

and plasma physics may revolutionize the entire landscape 

Training of future accelerator scientists is crucial to ensure 

continuing progress in the field 

Research and training in the area of accelerator-laser-plasma give 

variety of science opportunities, possibilities for inter-disciplinary 

research & enhance connection of academic research with industry 

Dynamic research and training programme in accelerator science, at 

the forefront of national and international arena, is the aim of JAI

Modern methods of acceleration and compact light sources
