Book Description
Updated and expanded from the original Japanese edition, Laser-Aided Diagnostics of Gases and Plasmas takes a unique approach in treating laser-aided diagnostics. The book unifies the subject by joining applications instead of describing each application as a totally separate system. In taking this approach, it highlights the relative strengths of

Book Description
Currently particle accelerators such as the Large Hadron Collider use RF cavities with a maximum field gradient of 50-100 MV/m to accelerate particles over long distances. A new type of plasma based accelerator called a Laser Plasma Accelerator (LPA) is being investigated at the LOASIS group at Lawrence Berkeley National Laboratory which can sustain field gradients of 10-100 GV/m. This new type of accelerator offers the potential to create compact high energy accelerators and light sources. In order to investigate the feasibility of producing a compact light source an undulator-based electron beam diagnostic for use on the LOASIS LPA has been built and calibrated. This diagnostic relies on the principal that the spectral analysis of synchrotron radiation from an undulator can reveal properties of the electron beam such as emittance, energy and energy spread. The effects of electron beam energy spread upon the harmonics of undulator produced synchrotron radiation were derived from the equations of motion of the beam and numerically simulated. The diagnostic consists of quadrupole focusing magnets to collimate the electron beam, a 1.5 m long undulator to produce the synchrotron radiation, and a high resolution high gain XUV spectrometer to analyze the radiation. The undulator was aligned and tuned in order to maximize the flux of synchrotron radiation produced. The spectrometer was calibrated at the Advanced Light Source, with the results showing the ability to measure electron beam energy spreads at resolutions as low as 0.1% rms, a major improvement over conventional magnetic spectrometers. Numerical simulations show the ability to measure energy spreads on realistic LPA produced electron beams as well as the improvements in measurements made with the quadrupole magnets. Experimentally the quadrupoles were shown to stabilize and focus the electron beams at specific energies for their insertion into the undulator, with the eventual hope of producing an all optical Free Electron Laser operating in the XUV and soft x-ray regimes.

Book Description
We demonstrated single shot diagnostics of laser-plasma accelerators (LPAs). We observed the structure and the evolving process of the blow-out region, the nonlinear waves (plasma bubble) induced by the driving beam using the Faraday rotation diagnostic. We obtained the evolution of the plasma bubble in single shot using Faraday rotation diagnostic with multiple probe beams. The diameter of the bubble changed from 300 [micrometer] to 50 [micrometer] in 2 cm, which revealed the transition of the acceleration stages from ”bubble expanding mode” to ”bubble stabilizing mode”. Moreover, we demonstrated the broad bandwidth frequency domain streak camera (B-FDSC), which can resolve the dynamics of LPAs in single shot. We improved the temporal resolution of B-FDSC to 10 fs by broadening the bandwidth of the probe beam to 100 nm using supercontinuum generation, and we performed a prototype experiment to show that B-FDSC was capable of resolving the evolution of pulse self-steepening and temporal splitting in a single shot.
