Collimation of High Energy Electron Beams

The kinetic energy is then given by This is essentially defining the kinetic energy of a particle as the excess of the particle energy over its rest mass energy. lighter particle and a photon. A portion m 0 of its mass is used to create a photon having energy E = m 0c2 and momentum p = E =c= m 0c. We guessed that energy and momentum are still conserved in relativistic problems, so that by conservation of momentum the particle produced in the decay has energy E f = (M 0 m 0)c2 and momentum p f = +m 0c. During a molecular, atomic or nuclear transition to a lower energy level, photons of various energy will be emitted, ranging from radio waves to gamma rays. Photons can also be emitted when a particle and its corresponding antiparticle are annihilated (for example, electron–positron annihilation).: 572,1114,1172. Relativistic energy and momentum However the total energy of the particle E and its relativistic momentum p are frame-dependent; relative motion between two frames causes the observers in those frames to measure different values of the particle's energy and momentum; one frame measures E and p, while the other frame measures E ′ and p′, where E ′ ≠ E and p′ ≠ p, unless there is no relative motion between observers, in which case each observer measures the same energy and momenta.

Beam Energy and Centrality Dependence of Direct-Photon
