Presentations

The development of high gradient acceleration and tight phase-space control of high power beams is a key element for future lepton and hadron colliders since the increasing demands for higher energy and luminosity significantly raise costs of modern HEP facilities. Atomic channels in crystals are known to consist of 10 – 100 V/Å potential barriers capable of guiding and collimating a high...

10. Propagation of ultra-intense laser pulses in near-critical plasmas: depletion mechanisms

Arkady Gonoskov (Chalmers University of Technology)

Presentations

Although the weakly nonlinear regime of LWFA is known to be the optimal for reaching the highest possible energy of electrons for a laser pulse of given energy, the capabilities of upcoming grand laser systems will provide the possibility of running highly nonlinear regimes of laser pulse propagation in underdense or near-critical plasmas. These regimes could open new routes towards various...

65. Generation of an ultrashort monoenergetic proton bunch in an instability-free regime by a single-cycle laser pulse

Presentations

Prompted by the possibility1 to produce high energy single cycle laser pulse in the tens of PW intensity (1024W=cm2), we have investigated laser-matter interaction in the few optical cycle and ultra relativistic intensity regime. A particularly interesting instability-free regime for ion production was revealed leading to the efficient production of short(fs) monoenergetic ions with a peak...

63. Vacuum laser acceleration of relativistic electrons using plasma mirror injectors

Fabien Quere (CEA)

Presentations

Vacuum Laser Acceleration (VLA) [1] is a promising method for accelerating electrons to very high energy in very short distances. The method is appealing because of its conceptual simplicity and most fundamental nature: electrons interact with an intense laser field in vacuum and exchange energy with the field. With intensities exceeding $10^{19} W/cm^{2}$, the laser electric field reaches >10...

68. Plasma structures for coherent acceleration

Alexander Pukhov (University of Dusseldorf)

Presentations

By using our full electromagnetic relativistic particle-in-cell (PIC) simulation code equipped with ionisation module, we simulate the laser fields dynamics in the periodic structures of different materials. We study how the dynamic ionization influences the field structure.

78. Dielectric Laser Acceleration of Sub-relativistic Electrons – Towards Realization of an Accelerator on a Chip

Dr Kozak Martin (Department of Physics, Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), Staudtstr. 1, D-91058 Erlangen, Germany)

Presentations

We report on recent experimental progress in the field of dielectric laser acceleration (DLA) of electrons, with a focus on our recent results at sub-relativistic energies. This novel concept utilizes principles established in RF technology but scales down the size of the analogous accelerator components by several orders of magnitude, driven by the high achievable acceleration gradients of...
