A model-independent approach to mixing in prompt $D^{0} \rightarrow K_S^0 \pi^+ \pi^-$ decays at LHCb / Torr, Nicholas
This thesis presents a measurement of the charm mixing parameters $x_D$ and $y_D$ in prompt $D^{0} \rightarrow K_S^0 \pi^+ \pi^-$ decays using 1 fb$^{-1}$ of data collected by the LHCb experiment during 2011 [...]

Simulation Studies of Diffraction Radiation / Aumeyr, Thomas (Royal Holloway, U. of London) ; Ainsworth, Robert (Royal Holloway, U. of London) ; Karataev, Pavel (Royal Holloway, U. of London) ; Billing, Michael (Cornell U., CLASSE) ; Bobb, Lorraine (CERN) ; Bolzon, Benoit (CERN) ; Lefèvre, Thibaut (CERN) ; Mazzoni, Stefano (CERN)
Transition Radiation (TR) and Diffraction Radiation (DR) are produced when a relativistic charged particle moves through a medium or in the vicinity of a medium respectively. The target atoms are polarised by the electric field of the charged particle, which then oscillate thus emitting radiation with a very broad spectrum. [...]

A Space-charge Compatible "Tomography" of Beam Phase-space Distributions / Pichoff, Nicolas (IRFU, Saclay ; CEA, DSM, Saclay) ; Lasheen, Alexandre (CERN)
The well-known 3-gradient method allows accessing to a beam RMS emittance and Twiss parameters at a position A by measuring its rms size at a downstream position B with at least 3 different transport conditions from A to B. We suggest extending this method to access to a beam phase-space distribution model at A from beam profiles measured at B. [...]

Designs of High-intensity Proton Linacs with Non-equipartitioning / Meng, Cai (Beijing, Inst. High Energy Phys.) ; Li, Zhihui (Beijing, Inst. High Energy Phys.) ; Pei, Shilun (Beijing, Inst. High Energy Phys.) ; Sun, Biao (Beijing, Inst. High Energy Phys.) ; Tang, Jingyu (Beijing, Inst. High Energy Phys.) ; Yan, Fang (Beijing, Inst. High Energy Phys.) ; Garoby, Roland (CERN) ; Gerigk, Frank (CERN) ; Lombardi, Alessandra (CERN)
Superconducting technology is playing more and more important roles in high-power proton linacs. Periodic phase advance less than 90 degrees and equipartitioning design are considered very important principles in linac design. [...]
