Understanding and predicting complex dynamics in accelerators is necessary for their successful operation. A grand challenge in accelerator physics is to develop predictive virtual accelerators that mitigate design cost and schedule risk. Data-driven

Terawatt x-ray free-electron lasers (XFELs) represent the frontier in further development of x-ray sources and require high current densities with strong transverse focusing. In this paper, we investigate the implications/potentialities of TW XFELs o

High peak and average power free-electron lasers (FELs) in the terahertz region (THz) require small diameter, low-emittance, and high voltage electron beams. This paper presents two 1.5-2 MV, 100-200 A, thermionic cathode electron source approaches f

Prior work in the transformational leadership realm has focused primarily on relations among leader behaviors and various criteria such as subordinate satisfaction and effectiveness. This restrictive focus has limited the degree to which one of Bass'

Students at Colorado College and cadets at the US Air Force Academy have conducted an experimental test of gravitational time dilation. This relativistic effect, highlighted in the movie Interstellar, causes clocks to tick more slowly near massive ob

General relativity predicts that clocks run more slowly near massive objects. The effect is small---a clock at sea level lags behind one 1000 m above sea level by only 9.4 ns/day. Here, we demonstrate that a measurement of this effect can be done by

Los que se quedan : non-migrant experiences of emigration, absence and diaspora in contemporary Cuba
Autor:
O'Shea, Patrick
Fundamentally, this thesis explores emigration, exile and diaspora as central experiences of contemporary Cuban society and culture but, crucially, understands the processes of experience as lived mutually and simultaneously by both those who emigrat
