Book excerpt: At the heart of this thesis is the young field of free electron laser science, whose experimental and theoretical basics are described here in a comprehensible manner. Extremely bright and ultra short pulses from short wavelength free-electron lasers (FELs) have recently opened the path to new fields of research. The x-ray flashes transform all matter into highly excited plasma states within femtoseconds, while their high spatial and temporal resolution allows the study of fast processes in very small structures. Even imaging of single molecules may be within reach if ultrafast radiation damage can be understood and brought under control. Atomic clusters have proven to be ideal model systems for light-matter interaction studies in all wavelength regimes, being size scalable, easy-to-produce gas phase targets with a simple structure. With FELs, "single cluster imaging and simultaneous ion spectroscopy" makes possible experiments under extremely well defined initial conditions, because the size of the cluster and the FEL intensity can be extracted from the scattering images. For the first time large xenon clusters up to micron radius were generated. Their single cluster scattering images were analyzed for cluster morphology and traces of the ultrafast plasma built-up during the femtosecond FEL pulse. The simultaneously measured single cluster ion spectra yield unprecedented insight into the ion dynamics following the interaction. The results will feed both future experimental effort and theoretical modeling.

Download or read book Interaction of Clusters with Ultra Short X-ray Free Electron Laser Pulses written by Nirmala Krishna Kandadai and published by . This book was released on 2012 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomolecular imaging has become one of the most exciting potential applications of the Linear Coherent Light Source (LCLS), which is a source of intense femtosecond X-rays. It has been predicted that a highly intense pulse with pulse lengths on the order of a few femtoseconds should be sufficient to capture the image of a biomolecule before it is destroyed. However, the rate at which a large biomolecule explodes during exposure is a large unknown, and will likely be one of the major factors in determining if such imaging will succeed. Clusters were chosen as a size dependant model system, ideal to study the evolution of complex systems in X-ray fields. From earlier intense near-infrared (IR) experiments, it is known that depending on size and Z constitution, clusters explode by Coulomb or hydrodynamic forces. These two limits have very different cluster explosion times and signatures. Coulomb explosion is too fast to allow imaging, whereas a hydrodynamically expanding cluster is a much slower process. The ionization process leading to cluster explosion is strongly wavelength dependent as one passes from IR through XUV to the X-ray regime because the kinetic energy of the released electrons determines the charge imbalance within the cluster, and therefore, determines the explosion dynamics. Unlike in previous experiments performed with near IR or XUV pulses, irradiation by photons at the LCLS will lead to the ejection of energetic photo- and Auger- electrons which could easily escape from the cluster, leaving behind positive ions. The buildup of this charge during exposure can lead to a Coulomb explosion of the sample. On the other hand, if the charge accumulates, the photoelectrons will be held inside the cluster, where they could contribute to the cluster temperature and form a nanoplasma and expand hydrodynamically. The main goal of the thesis was to study the explosion dynamics of clusters generated due to their interaction with intense X-rays and look at its dependencies on the X-ray energy, photon fluence, absorption cross sections, sample constituency and sample size. This thesis also compares the results from X-rays with the corresponding results obtained using ultrashort XUV and Infrared lasers.

Download or read book High Intensity Femtosecond XUV Pulse Interactions with Atomic Clusters written by and published by . This book was released on 2016 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: We propose to expand our recent studies on the interactions of intense extreme ultraviolet (XUV) femtosecond pulses with atomic and molecular clusters. The work described follows directly from work performed under BES support for the past grant period. During this period we upgraded the THOR laser at UT Austin by replacing the regenerative amplifier with optical parametric amplification (OPA) using BBO crystals. This increased the contrast of the laser, the total laser energy to ~1.2 J, and decreased the pulse width to below 30 fs. We built a new all reflective XUV harmonic beam line into expanded lab space. This enabled an increase influence by a factor of 25 and an increase in the intensity by a factor of 50. The goal of the program proposed in this renewal is to extend this class of experiments to available higher XUV intensity and a greater range of wavelengths. In particular we plan to perform experiments to confirm our hypothesis about the origin of the high charge states in these exploding clusters, an effect which we ascribe to plasma continuum lowering (ionization potential depression) in a cluster nano-plasma. To do this we will perform experiments in which XUV pulses of carefully chosen wavelength irradiate clusters composed of only low-Z atoms and clusters with a mixture of this low-Z atom with higher Z atoms. The latter clusters will exhibit higher electron densities and will serve to lower the ionization potential further than in the clusters composed only of low Z atoms. This should have a significant effect on the charge states produced in the exploding cluster. We will also explore the transition of explosions in these XUV irradiated clusters from hydrodynamic expansion to Coulomb explosion. The work proposed here will explore clusters of a wider range of constituents, including clusters from solids. Experiments on clusters from solids will be enabled by development we performed during the past grant period in which we constructed and tested a cluster generator based on the Laser Ablation of Microparticles (LAM) method.

Available in PDF, EPUB and Kindle. Book excerpt: Hardly any other discovery of the nineteenth century did have such an impact on science and technology as Wilhelm Conrad Röntgen’s seminal find of the X-rays. X-ray tubes soon made their way as excellent instruments for numerous applications in medicine, biology, materials science and testing, chemistry and public security. Developing new radiation sources with higher brilliance and much extended spectral range resulted in stunning developments like the electron synchrotron and electron storage ring and the freeelectron laser. This handbook highlights these developments in fifty chapters. The reader is given not only an inside view of exciting science areas but also of design concepts for the most advanced light sources. The theory of synchrotron radiation and of the freeelectron laser, design examples and the technology basis are presented. The handbook presents advanced concepts like seeding and harmonic generation, the booming field of Terahertz radiation sources and upcoming brilliant light sources driven by laser-plasma accelerators. The applications of the most advanced light sources and the advent of nanobeams and fully coherent x-rays allow experiments from which scientists in the past could not even dream. Examples are the diffraction with nanometer resolution, imaging with a full 3D reconstruction of the object from a diffraction pattern, measuring the disorder in liquids with high spatial and temporal resolution. The 20th century was dedicated to the development and improvement of synchrotron light sources with an ever ongoing increase of brilliance. With ultrahigh brilliance sources, the 21st century will be the century of x-ray lasers and their applications. Thus, we are already close to the dream of condensed matter and biophysics: imaging single (macro)molecules and measuring their dynamics on the femtosecond timescale to produce movies with atomic resolution.

Download or read book Explosion Dynamics of Van Der Waals Clusters Using 38 Nm XUV Laser Pulses written by Ahmed Mohammed Helal and published by . This book was released on 2016 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of intense XUV laser pulses with matter and rare gas cluster has been the focus of the scientific community for decades. This focus has been sparked by the ongoing efforts to reach microscopy with atomic resolution, leading to a time resolved image on the scale of the atomic motion. The interest in van der Waals clusters appears due to it is similarity with the small bio-molecules, studying the behavior of these cluster will shed some light on how the biomolecules behavior under intense laser pulse. We have conducted a major upgrade to the UT THOR laser system, that enables us to achieve 17.7 nJ of XUV energy, produced by high harmonic generation, which is used to conduct multiple cluster experiments. We investigated the dynamics of rare-gas clusters produced by Ar and Xe gases, the ion time of flight, kinetic energy and electron energy have been measured, the generation of ion kinetic energy of two different temperatures (6 and 55 eV) due to hydrodynamic expansion was observed. For Xe clusters, we observed the generation of unexplained high charge states up to Xe9+, that could be due to the effect of continuum lowering and inner ionization of the giant resonance 4d-level. We also investigated the dynamics of small molecule clusters. Stating with nitrogen clusters, we noticed a dependence of the ionization ratio between N + 2 and N +on the cluster size has been noticed. In addition to that nitrogen clusters shows the highest ion kinetic energy generated between all the clusters investigated in this dissertation. The interaction of XUV laser pulses with Methane cluster is studied, we could not detect any high charges of methane fragments such as (CH2+ 4). However, we noticed that we generated multiple fragments by breaking C-H bonds (CH+ 3, CH+ 2, CH+) in addition to bare carbon with high cluster sizes. The generation of CH+ 5, H+ and H + 2 was also observed. Studying the partial yield of each of these reveals that the correlation between CH+ 5 and H+ is opposite to what is expected, which might be due to the change of the cluster properties or the expansion dynamic itself (towards more hydrodynamics).
