Texte intégralFor an X-ray free electron laser (FEL), a high-quality electron bunch with low emittance, high peak current and energy is needed. During the phases of acceleration, bunch compression and transportation, the electron beam is subject to radio frequency curvature and to wakefields effects. Thus, the energy profile of the electron beam can present a parabolic profile, which has important electromagnetic effects on the FEL process. The quality of the electron beam is also degraded by the interaction with the low-gap undulator vacuum chamber. In our work we first analyze this interaction, deriving a formula to evaluate the longitudinal and the transversal wakefields for an elliptical cross section vacuum chamber, obtaining accurate results in the short range. Subsequently within the Vlasov-Maxwell one-dimensional model, we derive the Green functions necessary to evaluate the radiation envelope, having as initial conditions both an energy chirp and curvature on the electrons and eventually an initial bunching, which is useful to treat the harmonic generation FEL cascade configuration. This allows to study the impact of the elecron beam energy profile on the FEL performance. Using the derived Green functions we discuss FEL radiation properties such as bandwidth, frequency shift, frequency chirp and velocity of propagation. Finally, we propose a method to achieve ultra-short FEL pulses using a frequency chirp on the seed laser and a suitable electron energy profile.

Natile, Michele. « High-repetition rate CEP-stable Yb-doped fiber amplifier for high harmonic generation ». Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLS149.
Texte intégralIn the last two decades, attosecond physics, based on the high harmonic generation (HHG) phenomenon, has allowed a better understanding of ultrafast dynamics in the microcosm. High-energy few-cycles carrier-envelope phase (CEP) stabilized sources are the main enabling tools for this physics. Recently, temporally compressed Ytterbium-doped fiber amplifiers have been successfully used as high XUV photon flux HHG drivers. CEP stabilization of these sources would ensure their full compatibility with attoscience. The thesis is devoted to the CEP stabilization of a high repetition rate Yb-doped fiber femtosecond source, for high XUV photon flux beamline applications. In the first part, we present the architecture of such a source at 100 kHz repetition rate delivering 30 microjoules 96 fs CEP-stable pulses. It constitutes a test bench for future energy-scaled few-cycle sources. The CEP stabilization is ensured in a hybrid architecture including a passively stabilized frontend followed by an actively stabilized power amplifier. A residual CEP noise <400 mrad is measured using various setups, including a shot-to-shot measurement over 1 s and a long-term stability over 1 h. In the second part, we discuss the design of a high flux HHG beamline optimized for a future generation of fiber-based driver at 13 nm for applications to coherent diffraction imaging
Pierce, Seth J. « Reducing stator current harmonics for a doubly-fed induction generator connected to a distorted grid ». Thesis, Monterey, California : Naval Postgraduate School, 2013. http://hdl.handle.net/10945/37693.
Texte intégralThe Department of Defense (DoD) is increasing its demand for reliable renewable energy sources. The doubly-fed induction generator (DFIG) is widely used to extract electrical energy from wind and is a useful means for the DoD to achieve its renewable energy goals. The DFIG is susceptible to electric grid voltage harmonics, which is a potential obstacle for implementing stable wind-energy systems. Two existing rotor voltage controllers are modeled in this thesis for eventual implementation in a laboratory DFIG wind energy system. The first controller uses multiple proportional-integral (PI) controllers to filter out the fifth and seventh stator current harmonics. Each PI controller operates in a reference frame that rotates in synchronicity with the harmonic that is being filtered. The second controller operates in the synchronous reference frame and simultaneously filters both the fifth and seventh stator current harmonics using a double integrator called a proportional-resonant controller (PR). The PI controller is shown to be more effective at eliminating the stator current than the PR controller but has a slower reaction time. The PR controller requires fewer computations but has more stability concerns. Both controllers reduce torque oscillations resulting from the grid distortion by approximately the same amount.

Texte intégralThis work presents a vector controller with the objective of reducing the electromagnetic torque and the active and reactive powers of the stator by means of control of the harmonics of the stator current in harmonic conditions of fifth, seventh, eleventh and thirteenth order of the stator voltage. The objective of the work is to propose a controller that uses two techniques already consolidated in the literature, proportional-integrative and discrete Fourier transform, besides being robust the main disadvantages of the existing harmonic controllers in the literature that are dependencies of the parameters of the machine and the Frequency of the network beyond the influence of the stator current delays on the harmonic controller. First, the influence of the fifth, seventh, eleventh, eleventh and thirteenth order harmonics of the stator voltage on the harmonics of the stator current and on the undulations of the electromagnetic torque and the active and reactive powers of the stator are studied. Next, simulation results evaluate the proposed controller under adverse conditions: parametric variations and the frequency of the network, besides the influence of stator current delays. Finally, experimental results validate the controller under conditions that the controller reference is nonzero.
