Do we really need High energy?
l = h / p (de Broglie, 1924)
where h = Planck’s constant = 6.63 x 10-34 Js
p = momentum of protons
Particle energies are measured in electron-volts (eV).
1 eV is the amount of energy an electron gains when it
moves through an electric field of one volt.
So CERN dug out Million tons of earth just to smash tiny particles
(Angels and demons)

• Equation of state, phase transitions, transport phenomena
• Matter under high pressure
• Interaction of ions and photons with plasma
Dynamic electric fields (upto 1020 V/cm) produced in collisions of
heavy ion beams give access to
• Spectroscopy upto the limits of atomic matter
• QED in non-perturbative regime
• Precision determination of fundamental constants
• Infuence of atomic structure on nuclear decay properties
High intensity beams will be used on bio and material targets to
