Book excerpt: Efficient laser ion acceleration requires high laser intensities, which can only be obtained by tightly focusing laser radiation. In the radiation pressure acceleration regime, where the tightly focused laser driver leads to the appearance of the fundamental limit for the maximum attainable ion energy, this limit corresponds to the laser pulse group velocity as well as to another limit connected with the transverse expansion of the accelerated foil and consequent onset of the foil transparency. These limits can be relaxed by using composite targets, consisting of a thin foil followed by a near critical density slab. Such targets provide guiding of a laser pulse inside a self-generated channel and background electrons, being snowplowed by the pulse, compensate for the transverse expansion. The use of composite targets results in a significant increase in maximum ion energy, compared to a single foil target case.

Book Synopsis Proton Acceleration in Ultra-Relativistic Laser-Plasma Interaction by : Tong-Pu Yu
Download or read book Proton Acceleration in Ultra-Relativistic Laser-Plasma Interaction written by Tong-Pu Yu and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rapid development of laser systems, plasma-based laser-driven ion acceleration has drawn increasing attention these years. In this book, one of the most efficient and promising ion acceleration mechanisms, so-called radiation pressure acceleration or light-sail regime is re-visited and studied in detail by theoretical analysis and multi-dimensional particle-in-cell (PIC) simulations. Based on a simple "flying plasma mirror" model, accurate scaling laws of the final ion energy, velocity, momentum, and energy coupling efficiency in the light-sail regime have been derived. For smooth proton acceleration, a shaped foil target or a density-modulated foil target is suggested to overcome the foil deformation when a transversely Gaussian laser pulse irradiates the foil. GeV proton beams can be generated with a well-defined quasi-monoenergetic feature in the energy spectrum. For stable proton acceleration in the light-sail regime, a two-ion-species shaped foil target is proposed and demonstrated by a series of PIC simulations. Hard X-ray gernation and attosecond electron beams are also stuided and verified in the light-sail regime.
Book Synopsis Experimental Studies of Laser Driven Proton Acceleration from Ultrashort and Highly Intense Laser Pulse Interaction with Overdense Plasma by : Donghoon Kuk
Download or read book Experimental Studies of Laser Driven Proton Acceleration from Ultrashort and Highly Intense Laser Pulse Interaction with Overdense Plasma written by Donghoon Kuk and published by . This book was released on 2014 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: The generation of high current multi-MeV protons and ions by irradiation of short pulse high intense laser on an ultra-thin target has been observed and subjected great interest in recent. When ultra-thin overdense target is irradiated by focused ultraintense laser pulse, hot electrons are generated by various mechanisms and they generate energetic ion beams. In TNSA, a quasi-electrostatic field is produced on the target rear surface when the the laser pulse interacts with overdense target, driving hot electrons go torward the target rear surface. However, this mechanism results in a range of field gradients leading to a broad proton energy distribution typically. To overcome the issue, an alternative accelration mechanism has been presented to achieve the quasi-monoenergetic proton acceleration and the mechanism is called Radiation Pressure Acceleration. In the RPA, the radiation pressure push electrons into the target smoothly and setting up an electrostatic field by the laser pressure. In this thesis, we study two alternative experimental methods for the quasi-monoenergetic proton acceleration and find experimental feasibility of the presented methods from other research groups.

This book was released on 2016 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of our work is to provide theoretical basis and modeling support for the design and experimental setup of compact laser proton accelerator to produce high quality proton beams tunable with energy from 50 to 250 MeV using short pulse sub-petawatt laser. We performed theoretical and computational studies of energy scaling and Raleigh--Taylor instability development in laser radiation pressure acceleration (RPA) and developed novel RPA-based schemes to remedy/suppress instabilities for high-quality quasimonoenergetic proton beam generation as we proposed. During the project period, we published nine peer-reviewed journal papers and made twenty conference presentations including six invited talks on our work. The project supported one graduate student who received his PhD degree in physics in 2013 and supported two post-doctoral associates. We also mentored three high school students and one undergraduate student of physics major by inspiring their interests and having them involved in the project.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on a cutting-edge area of research, which is aligned with CERN's mainstream research, the "AWAKE" project, dedicated to proving the capability of accelerating particles to the energy frontier by the high energy proton beam. The author participated in this project and has advanced the plasma wakefield theory and modelling significantly, especially concerning future plasma acceleration based collider design. The thesis addresses electron beam acceleration to high energy whilst preserving its high quality driven by a single short proton bunch in hollow plasma. It also demonstrates stable deceleration of multiple proton bunches in a nonlinear regime with strong resonant wakefield excitation in hollow plasma, and generation of high energy and high quality electron or positron bunches. Further work includes the assessment of transverse instabilities induced by misaligned beams in hollow plasma and enhancement of the wakefield amplitude driven by a self-modulated long proton bunch with a tapered plasma. This work has major potential to impact the next generation of linear colliders and also in the long-term may help develop compact accelerators for use in industrial and medical facilities.

Book Synopsis Laser Acceleration of Protons Using Multi-ion Plasma Gaseous Targets by :
Download or read book Laser Acceleration of Protons Using Multi-ion Plasma Gaseous Targets written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a theoretical and numerical study of a novel acceleration scheme by applying a combination of laser radiation pressure and shielded Coulomb repulsion in laser acceleration of protons in multi-species gaseous targets. By using a circularly polarized CO2 laser pulse with a wavelength of 10 [mu]m--much greater than that of a Ti: Sapphire laser--the critical density is significantly reduced, and a high-pressure gaseous target can be used to achieve an overdense plasma. This gives us a larger degree of freedom in selecting the target compounds or mixtures, as well as their density and thickness profiles. By impinging such a laser beam on a carbon-hydrogen target, the gaseous target is first compressed and accelerated by radiation pressure until the electron layer disrupts, after which the protons are further accelerated by the electron-shielded carbon ion layer. An 80 MeV quasi-monoenergetic proton beam can be generated using a half-sine shaped laser beam with a peak power of 70 TW and a pulse duration of 150 wave periods.

Download or read book Enhancement of Proton Acceleration from Focusing Targets written by Herbie Lamar Smith and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle acceleration from laser-plasma interactions has been a vibrant area of research since the discovery of electron and proton beams emitted from high intensity laser-plasma interactions in the 1980s. Since then, a large body of work has developed in pursuit of understanding and controlling the mechanisms that generate these particle beams, as well as the beams themselves. In particular, proton beams have a rich set of applications in the fields of medicine, fusion energy, and fundamental physics that motivates their study. In this thesis, we first discuss the laser technology that has enabled this research. We follow this with detailed information on the design and development of a 100 TW power upgrade to the graduate student-run GHOST laser system for the purposes of conducting repetition-rated laser-plasma experiments. We then outline the physics that drives particle acceleration during the interactions of high intensity lasers and solid targets with a particular focus on target normal sheath acceleration, the most widely studied laser-plasma particle acceleration mechanism. Finally, we describe experiments conducted on the Texas Petawatt Laser system to test an approach to enhance the yield, peak energy, and beam characteristics of proton beams generated by laser-plasma interactions with the use of focusing targets
