Book Description
Quantum logic gates are the crucial information-processing operation of quantumcomputers. Two crucial performance metrics for logic gates are their precision andspeed. Quantum processors based on trapped ions have always been the touchstonefor gate precision, but have suffered from slow speed relative to other quantum logicplatforms such as solid state systems. This thesis shows that it is possible to acceleratethe logic "clock speed" from kHz to MHz speeds, whilst maintaining a precision of99.8%. This is almost as high as the world record for conventional trapped-ion gates,but more than 20 times faster. It also demonstrates entanglement generation in atime (480ns) shorter than the natural timescale of the ions' motion in the trap, whichstarts to probe an interesting new regime of ion trap physics. In separate experiments, some of the first "mixed-species" quantum logic gates areperformed, both between two different elements, and between different isotopes.The mixed-isotope gate is used to make the first test of the quantum-mechanical Bellinequality between two different species of isolated atoms.

Book Description
This thesis presents profound insights into the origins and dynamics of beam instabilities using both experimental observations and numerical simulations. When the Recycler Ring, a high-intensity proton beam accelerator at Fermi National Accelerator Laboratory, was commissioned, it became evident that the Recycler beam experiences a very fast instability of unknown nature. This instability was so fast that the existing dampers were ineffective at suppressing it. The nature of this phenomenon, alongside several other poorly understood features of the beam, became one of the biggest puzzles in the accelerator community. The author investigated a hypothesis that the instability arises from an interaction with a dense cloud of electrons accompanying the proton beam. He studied the phenomena experimentally by comparing the dynamics of stable and unstable beams, by numerically simulating the build-up of the electron cloud and its interaction with the beam, and by constructing an analytical model of an electron cloud-driven instability with the electrons trapped in combined-function dipole magnets. He has devised a method to stabilize the beam by a clearing bunch, which conclusively revealed that the instability is caused by the electron cloud, trapped in a strong magnetic field. Finally, he conducted measurements of the microwave propagation through a single dipole magnet. These measurements have confirmed the presence of the electron cloud in combined-function magnets.

Book Description
Byron is safe. Zandria has committed herself to life as a fast-tracker, but she's determined to make the most of it. As a first-generation fast-tracker, Zandria is a designated newbie. Most fast-trackers considered her a temporary interloper, but her recent business acquisitions, and especially her engagement, changed everything. With her recently secured internship, Zandria plans to immerse herself in politics. As high-ranking politician Zandria could improve worker-level conditions and combat fast-tracker corruption. Everything Zandria has learned about fast-trackers isn't enough to prepare her for their politics or marriage. Zandria is in over her head but she fears there's nothing she can do about it. She trapped.

Book Description
The day the blizzard started, no one knew that it was going to keep snowing for a week. That for those in its path, it would become not just a matter of keeping warm, but of staying alive. . . .Scotty and his friends Pete and Jason are among the last seven kids at their high school waiting to get picked up that day, and they soon realize that no one is coming for them. Still, it doesn't seem so bad to spend the night at school, especially when distractingly hot Krista and Julie are sleeping just down the hall. But then the power goes out, then the heat. The pipes freeze, and the roof shudders. As the days add up, the snow piles higher, and the empty halls grow colder and darker, the mounting pressure forces a devastating decision. . . .Michael Northrop is the New York Times bestselling author of TombQuest, an epic book and game adventure series featuring the magic of ancient Egypt. He is also the author of Trapped, an Indie Next List Selection, and Plunked, a New York Public Library best book of the year and an NPR Backseat Book Club selection.

Book Description
"When Floyd Collins became trapped in a cave in southern Kentucky in early 1925, the sensationalism and hysteria of the rescue attempt generated America's first true media spectacle, making Collins's story one of the seminal events of the century. The crowds that gathered outside Sand Cave turned the rescue site into a carnival. Collins's situation was front-page news throughout the country, hourly bulletins interrupted radio programs, and Congress recessed to hear the latest word. Trapped! is both a tense adventure and a brilliant historical recreation of the past. This new edition includes a new epilogue revealing information about the Floyed Collins story that has come to light since the book was first published.

Book Description
Jesse Rigsby hates video games—and for good reason. You see, a video game character is trying to kill him. After getting sucked in the new game Full Blast with his friend Eric, Jesse starts to see the appeal of vaporizing man-size praying mantis while cruising around by jet pack. But pretty soon, a mysterious figure begins following Eric and Jesse, and they discover they can't leave the game. If they don't figure out what's going on fast, they'll be trapped for good! With black-and-white illustrations throughout and a cliff hanger at the end of every chapter, this is a great series for kids who think they don’t like to read!

Book Description
Fundamental physics with trapped particles (ions, atoms or molecules) rep resents one of the most challenging and promising fields of investigation, with impressive results during this last decade. The use of both particle trapping and laser cooling techniques, together with traditional techniques of atomic physics, represents a powerlul tool of investigation for a wide range of fields. Experiments spanning very high resolution spectroscopy to Bose-Einstein condensation, tests of the Standard Model ofelectroweak interactions to precise mass measurements, detailed analysis of ~ decay to QED tests have been presented by leading scientists who reported the most recent results and discussed the perspectives in the different fields. During the ten working days of the School, 39 lecturers, 6 seminars and two poster sessions have been organized by offering to the attendants a.complete pic ture of the present research status about the new frontiers of atomic physics. L. Caneschi gave a general overview of the Standard Model of electroweak interac tions. He pointed out the achievements and the limits of validity of the model.

Book Description
In 2010, the ALPHA collaboration achieved a first for mankind: the stable, long-term storage of atomic antimatter, a project carried out a the Antiproton Decelerator facility at CERN. A crucial element of this observation was a dedicated silicon vertexing detector used to identify and analyze antihydrogen annihilations. This thesis reports the methods used to reconstruct the annihilation location. Specifically, the methods used to identify and extrapolate charged particle tracks and estimate the originating annihilation location are outlined. Finally, the experimental results demonstrating the first-ever magnetic confinement of antihydrogen atoms are presented. These results rely heavily on the silicon detector, and as such, the role of the annihilation vertex reconstruction is emphasized.

Book Description
Trapped by Malays: A Tale of Bayonet and Kris by George Manville Fenn is about incorrigible soldier Archibald Maine and the mischief he gets up to in Malaysia. Excerpt: "Oh, bother!" The utterer of these two impatient words threw down a sheet of notepaper from which he had been reading, carefully smoothed out the folds to make it flat, and then, balanced it upon one finger as he sat back in a cane chair with his heels upon the table, gave the paper a flip with his nail and sent it skimming out of the window of his military quarters at Campong Dang, the station on the Ruah River, far up the west coast of the Malay Peninsula."
