Abstract:

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2005.<br>Includes bibliographical references (p. 125-131).<br>We present theoretical and experimental results from a Smith-Purcell radiation experiment using the electron beam from a 17 GHz high gradient accelerator. Smith- Purcell radiation occurs when a charged particle travels above a periodic grating structure. The electron beam consists of a train of 15 MeV, 9 pC bunches of bunch lengths varying from 600 fs to 1 ps. The radiated energy for one electron travelling above a periodic grating is solved.

Abstract:

The dynamics of atomic scale structures during structural change can be studied by Ultrafast Electron Diffraction (UED). The time resolution needed to reveal the fastest dynamics is 100 fs. Sub-angstrom structural resolution becomes possible with 1-1000 pC of charge necessary for diffraction pattern analysis during subtle structural changes. This combination of requirements cannot currently be realized due to the space-charge temporal broadening inherent to bunches of electrons of high fluence and short temporal duration. Simulations show that the incorporation of a specially designed Radio-Fr

Abstract:

The intra-beam repulsions play a significant role in determining the performances of free-electron devices when an high brilliance of the beam is required. The transversal and longitudinal spread of the beam, its energy and density are fundamental parameters in any beam experiment and different beam diagnostics are available to measure such parameters. A diagnostic method based on the Thomson backscattering of a laser beam impinging on the particle beam is proposed in this work for the study of nanosecond electron bunches in high space charge regime.

The free electron laser (PEL) is a source of microwave power which makes use of the interaction between the electron beam and electromagnetic radiation.

Historically, the ebb tidal delta was extremely large, due to the presence of the south channel of Pass-A-Grille Pass. As the tidal prism decreased through the south channel, the sheltering effect produced by the large ebb tidal delta diminished, and large volumes of sand began migrat

Abstract:

At CERN, the European Organization for Nuclear Research, radioactive nuclear beams are produced at the On-Line Isotope Mass Separator facility, ISOLDE. This facility provides a variety of exotic nuclear species for multidisciplinary experiments including nuclear physics. A gas-filled linear Paul trap was integrated at the focal plane of the high resolution separator magnets. Ion beams with reduced transverse emittance and energy spread are now available for all experiments located downstream the separator beam line. This deace is also able to accumulate the ion beam and release the collected s
