Abstract Details

2012, Doctor of Philosophy, Ohio State University, Physics.
With the commissioning of the Linac Coherent Light Source (LCLS), the first x-ray free electron laser (XFEL) was realized at the Stanford Linear Accelerator Center. This novel device brings an unprecedented parameter set to a diverse community of scientists. The short wavelengths and short pulse durations enable an entire new class of time resolved structural analysis. The imaging capabilities enabled by the machine will lead to many breakthroughs in the fields of biophysics and nano technology. With the new capabilities of the LCLS come many challenges. The understanding re- quired to effectively utilize the XFEL on complex molecular or biological systems goes back to the basic atomic physics of the interaction of light and matter. The parameter set of this machine is as unprecedented as it will be untested. To make informed measurements with the LCLS beam, a set of novel diagnostic techniques will be required. This report outlines major contributions made to the early experimental atomic physics and diagnostic efforts at LCLS. Building on a rich history of techniques used for ultra short optical lasers and atomic physics experimentation, a diagnostic instrument and experimental techniques are developed to make spectral, energy and temporal measurements of the LCLS pulses possible. Expanding on earlier studies of ionization performed on optical lasers and synchrotron sources, new ionization mechanisms such as multiphoton ionization in the x-ray regime are are observed. Leveraging the unique combination of hard x-ray photon energy, extremely short pulse duration and high pulse energy, a technique for the time resolved study of ultrafast inner shell electronic relaxation processes is developed and studied for feasibility. The common theme to the efforts described here is the advancement of proven techniques and interesting atomic physics phenomena to the next generation of ultra short pulsed x-ray laser systems. The atomic physics explored here lay the groundwork for the next level of understanding the new experiments to be performed on molecular, biological and condensed phase systems using XFEL light pulses. The application of basic atomic physics established over the past 40 years with optical laser systems to diagnostic techniques suitable for the new properties of XFELs will lend crucial insight into the orchestration of future XFEL experiments.
