Compact LWFA-Based Extreme Ultraviolet Free Electron Laser: Design Constraints
Compact LWFA-Based Extreme Ultraviolet Free Electron Laser: design constraints Alexander Molodozhentsev∗, Konstantin O. Kruchinin Institute of Physics ASCR, v.v.i. (FZU), ELI-Beamlines, Za Radnici 835 Dolni Brezany 25241, Czech Republic Abstract Combination of advanced high power laser technology, new acceleration methods and achievements in undulator development opens a way to build compact, high brilliance Free Electron Laser (FEL) driven by a laser wakefield accelerator (LWFA). Here we present a study outlining main requirements on the LWFA based Extreme Ultra Violet (EUV) FEL setup with the aim to reach saturation of photon pulse energy in a single unit commercially available undulator with the deflection parameter K0 in a range of (1÷1.5). A dedicated electron beam transport which allows to control the electron beam slice parameters, including collective effects, required by the self-amplified spontaneous emission (SASE) FEL regime is proposed. Finally, a set of coherent photon radiation parameters achievable in the undulator section utilizing best experimentally demonstrated electron beam parameters are analyzed. As a result we demonstrate that the ultra-short (few fs level) pulse of the photon radiation with the wavelength in the EUV range can be obtained with the peak brilliance of ∼2×1030 photons/s/mm2/mrad2/0.1%bw if the driver laser operates at the repetition rate of 25 Hz. Keywords: laser wake field acceleration, free electron laser, electron beam transport 1. Introduction transport design for a compact laser based EUV-FEL. We demonstrate that proposed setup is capable to generate high In recent years linac-based FELs as a deliverer of coherent brightness coherent photon radiation reaching energy saturation X-ray pulses changed the science landscape. -

A Brief Review of Plasma Wakefield Acceleration Arxiv:1908.07207V4
A Brief Review of Plasma Wakefield Acceleration Altan Cakir∗ and Oguz Guzel Department of Physics Eng., Istanbul Technical University, 34469, Istanbul, Turkey February 18, 2020 Abstract Plasma Wakefield Accelerators could provide huge acceleration gradients that are 10 - 1000 times greater than conventional radio frequency metallic cavities available in current accelerators and at the same time the size of plasma wakefield accelerators could be much smaller than today's most succesful colliders. This review gives brief explanations of the working principle of Plasma Wakefield Accelerators and shows the recent development of the field. The current challenges are given and the potential future use of Plasma Wakefield Accelerators are discussed. Keywords: plasma wakefield accelerator; laser wakefield acceleration, beam-driven plasma wakefield acceleration 1 Introduction Since the rise of the particle physics in the 20th century, the particle accelerators became crucial to further grasp the fundamental theories of the particle physics. Today, the particle accelerators are state-of-the-art technology and are able to test the governing forces and the interactions be- tween very tiny fractures of the visible matter. The current milestone, with a circumference of 27 kilometers is the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN), situated in the Franco-Swiss border. The LHC accelerates proton beams to nearly the speed of light gaining them an energy of 6.5 TeV. Today, the LHC is the biggest particle accelerator in the world and is financed by numerous countries across the Europe. A bigger accelerator, Future Circular Collider (FCC), is being designed. A conceptual design report for the FCC was submitted arXiv:1908.07207v4 [physics.acc-ph] 14 Feb 2020 in December 2018 stating that the FCC is planned to be hosted in a 100 kilometers-long tunnel [1]. -

A new type of accelerator that uses plasma wakefields promises gradients as high as some tens of billions of electron volts per meter. This would allow much smaller accelerators that could be used for a wide range of fundamental and applied research applications. One of the target applications is a plasma-driven free-electron laser (FEL), aiming at producing tunable coherent light using electrons traveling in the periodic magnetic field of an undulator. -

Laser-Plasma Acceleration Beyond Wave Breaking
PLASMA AND ULTRAFAST PHYSICS Laser-Plasma Acceleration Beyond Wave Breaking J. P. Palastro,1 B. Malaca,2 J. Vieira,2 D. Ramsey,1 T. T. Simpson,1 P. Fran ke,1 J. L. Shaw,1 and D. H. Froula1 1Laboratory for Laser Energetics, University of Rochester 2Instituto de Plasmas e Fusão Nuclear, Instituto Superior Técnico, Universidade de Lisboa Laser wakefield accelerators rely on the extremely high electric fields of nonlinear plasma waves to trap and accelerate electrons to relativistic energies over short distances. When driven strongly enough, plasma waves break, trapping a large population of the background electrons that support their motion. This limits the maximum electric field. We have discovered a novel regime of plasma wave excitation and wakefield acceleration that removes this limit, allowing for arbitrarily high electric fields. The regime, enabled by spatiotemporal shaping of laser pulses, exploits the property that nonlinear plasma waves with superluminal phase velocities cannot trap charged particles and are therefore immune to wave breaking. A laser wakefield accelerator operat- ing in this regime provides energy tunability independent of the plasma density and can accommodate the large laser amplitudes delivered by modern and planned high-power, short-pulse laser systems. Armed with a vision of smaller-scale, less-expensive accelerators and empowered by advances in laser technology, the field of “advanced accelerators” has achieved rapid breakthroughs in both electron and ion acceleration.1 In laser wakefield acceleration (LWFA), in particular, a high-intensity laser pulse drives a plasma wave that can trap and accelerate electrons with a field nearly 1000# larger than the damage-limited field of a conventional radio-frequency accelerator.2 Progress in the field of LWFA exploded with the advent of high-power, broadband amplifiers, which delivered ultrashort pulses with durations less than the plasma period. -
Introduction to Plasma Accelerators: the Basics
Published by CERN in the Proceedings of the CAS-CERN Accelerator School: Plasma Wake Acceleration, Geneva, Switzerland, 23–29 November 2014, edited by B. Holzer, CERN-2016-001 (CERN, Geneva, 2016) Introduction to Plasma Accelerators: the Basics R.Bingham1,2 and R. Trines1 1Central Laser Facility, Rutherford Appleton Laboratory, Chilton, Didcot, Oxfordshire, UK 2Physics Department, University of Strathclyde, Glasgow, UK Abstract In this article, we concentrate on the basic physics of relativistic plasma wave accelerators. The generation of relativistic plasma waves by intense lasers or electron beams in low-density plasmas is important in the quest for producing ultra-high acceleration gradients for accelerators. A number of methods are being pursued vigorously to achieve ultra-high acceleration gradients using various plasma wave drivers; these include wakefield accelerators driven by photon, electron, and ion beams. We describe the basic equations and show how intense beams can generate a large-amplitude relativistic plasma wave capable of accelerating particles to high energies. We also demonstrate how these same relativistic electron waves can accelerate photons in plasmas. Keywords Laser; accelerators; wakefields; nonlinear theory; photon acceleration. 1 Introduction Particle accelerators have led to remarkable discoveries about the nature of fundamental particles, pro- viding the information that enabled scientists to develop and test the Standard Model of particle physics. The most recent milestone is the discovery of the Higgs boson using the Large Hadron Collider—the 27 km circumference 7 TeV proton accelerator at CERN. On a different scale, accelerators have many applications in science and technology, material science, biology, medicine, including cancer therapy, fusion research, and industry. -
