The scattering of fast neutrons by lead. Construction of an ion source and accelerating tube
… the Rice Institute Cockcroft-Walton high voltage particle accelerator. In previous experiments with the Cockcroft-Walton set, the voltage obtained was limited by breakdown across the single accelerating gap. The second purpose of the work was to eliminate this limitation by substitution of a set …

The ruins of science : whatever happened to the Tevatron?
The Tevatron was the world's highest energy particle accelerator for more than two decades. Built at Fermi National Accelerator Laboratory in Batavia, Illinois in the early 1980s, the machine accelerated protons and antiprotons through its 4.26-mile ring of magnets and smashed them together in one …

Microwave accelerating structures: an innovative parallel coupled electron LINAC
Particle accelerators are employed in many fields of the physics, engineering and medicine science. Although the idea of acceleration of charged particles by means of time varying electromagnetic field is an almost century old, the research and development in this field is active more than ever. An …

Flavourful beyond the Standard Model physics at current and future colliders
The Standard Model of particle physics successfully explains nearly all non-gravitational phenomena observed in nature. Yet, both theoretical considerations and experimental data suggest that the model is incomplete and must be extended. This thesis investigates "flavourful" beyond the Standard …
