Rumi

changing in energy of particles in a particle accelerator is a process which takes time in the electron time-scale.?
+++++++++++++++++
Dance, as though no one is watching you,
Love, as though you have never been hurt before,
Sing, as though no one can hear you,
Work as though you don't need the money,
Live, as though heaven is on the earth.
++Rumi , Iranian Poet, 13th century.++

Equilibrium

In a vacuun pipe of a particle accelerator, more you focus, more you need to defocuss.. Do particles need any VETO right during their life time?
