Measurement and correction of charged particle beam optics have been a major concern since the advent of strong focusing synchrotron accelerators. Traditionally, particle colliders have led the development of optics control based on turn-by-turn beam centroid measurements, while lepton storage rings have focused on closed-orbit-response matrix techniques. Recently, considerable efforts are bein...

Compared with state-of-the-art radio frequency accelerators, the gradient of laser wakefield accelerators is 3–4 orders magnitude higher. This great significance in development miniaturized particle and radiation sources. Higher requirements have been proposed for quality electron beams, owing to increasing application tabletop sources, specifically rapid free-electron devices. review briefly e...

After the historical background concerning the pressure of light, we derive the quantum field theory force of the laser radiation acting on electron. Numerically, we determine the velocity of an electron accelerated by laser beam, after acceleration time ∆t = 1s. 1 Why laser acceleration ? The problem of acceleration of charged particles by the laser field is, at present time, one of the most p...

081002-1 The interaction between a low-density electron cloud in a circular particle accelerator with a circulating charged particle beam is considered. The particle beam’s space charge attracts the cloud, enhancing the cloud density near the beam axis. It is shown that this enhanced charge and the image charges associated with the cloud charge and the conducting wall of the accelerator may hav...

We estimate that the vacuum electric field associated with a spinning Magnetospheric Eternally Collapsing Object MECO[1, 2, 3, 4, 5, 6, 7, 8, 9] could be higher by a factor of ∼ 10 than the corresponding pulsar value because of extreme relativistic Frame Dragging Effect. Thus isolated spinning MECOs could be source of UHE cosmic ray acceleration and VHE γ-ray production. However because of the ...

In this paper it is shown that temperatures up to 108 ° K and under densities of the order 1 g/cm3 are attainable in liquid tritium-deuterium by the impact shock waves of small solid particles accelerated up to velocities of some 107 cm/s in heavy particle accelerators. The high temperatures occur in a focussed particle beam. It is shown that under feasible conditions, the particle beam will ge...

We present PLATO (Perturbative Lattice Analysis and Tracking tOols), a program library for analysing four-dimensional betatronic motion in circular particle accelerators. The 136 included routines provide both the resonant and the non-resonant perturbative series that approximate nonlinear motion (normal forms); standard numerical tools such as the Lyapunov exponent, frequency analysis and eval...
