Instructor(s): | W. Hillert | |
Prerequisites: | Mechanics, Electrodynamics | |
Contents: | Die neuere experimentelle Physik basiert zum Teil auf dem Einsatz von Teilchenbeschleunigern, insbesondere im Bereich der Hochenergiephysik, der Materialforschung und der Erforschung der Substruktur der Atomkerne und der Hadronen. Durch die aktuellen wissenschaftlichen Fragestellungen wurden und werden auch weiterhin ständig gesteigerte Herausforderungen an den Betrieb und die Entwicklung von Teilchenbeschleunigern gestellt, was zum Einsatz modernster Technologien aus einer Vielzahl von physikalischen Bereichen führte. Als Beispiele mögen hier der Aufbau des ca. 27 km langen, fast vollständig supraleitenden Large Hadron Colliders (LHC) am CERN / Genf oder des 1 Angström Röntgenlasers (XFEL) am DESY / Hamburg dienen. Im Zuge dieser Entwicklungen und systematischen Untersuchungen der physikalischen Vorgänge in Beschleunigern entstand die Beschleunigerphysik als eigenständiger Fachbereich der angewandten Physik. Die vorliegende Vorlesung ist eine Einführung in die Beschleunigerphysik. Sie gibt einen Überblick über die verschiedenen Funktionsweisen unterschiedlicher Beschleunigertypen und führt, neben einer physikalischen Behandlung der wichtigsten Subsysteme (Teilchenquellen, Magnete, Hochfrequenzresonatoren), in die transversale und longitudinale Strahldynamik ein. More recent experimental physics is partly based on the use of particle accelerators, especially in high energy physics, materials research and exploration of the substructure of atomic nuclei and hadrons. Due to the current scientific questions, more and more demanding challenges have been and still are posed to the operation and development of particle accelerators, thus leading to the use of state-of-the-art high technology taken from a multitude of fields in physics. As examples may be cited the construction of the 27 km, almost entirely superconducting Large Hadron Collider (LHC) at CERN / Geneva or the Angström X-ray laser (XFEL) at DESY / Hamburg. In the course of these developments and systematic investigation of the physical processes in particle accelerators, particle accelerator physics emerged as a stand-alone field of applied physics. The present lecture is meant as an introduction into particle accelerator physics. It provides an overview of the various functional principles of different accelerator types and provides, alongside a physical treatment of the most important subsystems (particle sources, magnets, resonant cavities), an introduction into transversal and longitudinal orbit dynamics.

Instructor(s): | E. von Törne | |
Prerequisites: | ||
Contents: | BCGS Intensive Week, Statistical and Computational Methods for Experimental Particle Physics at LHC 22-26. September, Conference room-II, Physikalisches Institut Bonn This course will of interest both for students starting their master studies, students who start their master project soon, Ph.D. students from other fields of physics who wish to broaden their horizon. The BCGS intensive week aims at providing a detailed insight of an LHC detector and the experiments that are done with them to address important questions of fundamental physics today. About half of the course is devoted to hand-on projects. We will offer two topics in parallel:
What does one need to know to analyse LHC data? While following these lines, particular emphasis is given to - the scientific and technical requirements of LHC detectors - the physics of tracking and energy detectors - the theoretical background of LHC physics (Standard Model + Higgs physics) - the experimental methods to address these physics questions Of course, not all topics can be addressed to depth within one week. Thus an effort is made that students will receive an overview and understand the most important mechanisms. | |

physics742 | Ultracold Atomic Gases: Experiment and Theory Tu 14-16, Th 12-14, HS, IAP |
|
Instructor(s): | M. Köhl, C. Kollath | |
Prerequisites: | Atomic physics (e.g. phys411); Quantum mechanics (e.g. phys420) | |
Contents: | Almost hundred years ago, in 1924, A. Einstein and S.N. Bose predicted the existence of a new state of matter, the so-called Bose-Einstein condensate. It took 70 years to successfully realize this macroscopic quantum state in the lab using ultracold atomic gases (Nobel prize 2001). The main challenge was to achieve cooling to Nanokelvin temperatures, the coolest temperatures ever reached by mankind. Nowadays, ultracold gases are exciting systems to study a broad range of quantum phenomena. These phenomena range from the direct observation of quantum matter waves and superfluidity over the creation of artificial crystal structures as analogous to solids, to the realization of complex quantum phase transitions of interacting atoms, e.g. the formation of a bosonic Mott-insulator or the BCS superconducting state for Fermions. In this lecture we will discuss both the experimental and theoretical concepts of ultra-cold atomic gases. Outline: Introduction and revision of basic concepts, Fundamentals of atom- laser interaction Laser cooling & trapping, Bose-Einstein condensation of atomic gases. Dynamics of Bose-Einstein condensates Optical lattices: strongly interacting atomic gases and quantum phase transitions The crossover of Fermi-gases between a BCS superconducting state and a Bose- Einstein condensate of molecules. | |

physics774 | Electronics for Physicists Tu 14-16, Th 12, HS, HISKP |
|
Instructor(s): | P.-D. Eversheim | |
Prerequisites: | Practical course in electronics | |
Contents: | One of the "classic" abilities of an experimentalist is to build those instruments himself he needs but can not get otherwise. In this context the knowledge of electronics - in view of the growing electronics aided acquisition and control of experiments - becomes a key skill of an experimentalist. The intention of this lecture is to enable the students by means of exemplary experiments to work out concepts to solutions for given problems. A focus of this lecture is to show that many of these solutions or concepts to solutions, respectively, are used in other fields of physics too (quantum mechanics, optics, mechanics, acoustics, . . .). At the end of this lecture, the student should: i) have an overview over the most common parts in electronics. ii) be concious about the problems of handling electronic parts and assemblies. iii) understand the concepts that allow an analysis and synthesis of the dynamic properties of systems. | |

Prerequisites: | Required: Introductory particle physics course Physik511 (Physik V). Useful: Physics611 (Particle Physics) can be attended in parallel. | |
Contents: | In 2012, the ATLAS and CMS experiments at CERN announced the discovery of a new particle consistent with a Higgs boson. However, several further studies are still needed to determine whether all properties of the observed boson are exactly as predicted in the Standard Model. Will these studies turn out to be a window to new physics? And is there only one or maybe several Higgs bosons? In this seminar, we will discuss a variety of analyses (incl. experimental techniques) that will help pin down the exact nature of the observed boson as well as ongoing and future searches for new physics at the LHC and future colliders. Some possible topics for the seminar are: Higgs phenomenology at hadron colliders Higgs discovery in various decay channels Measurements of the Higgs properties (QNs, width, Yukawa couplings, ...) Searches for Higgs bosons beyond the Standard Model Higgs as a window to new physics (invisible decays, differential distributions, ...) Precision Higgs physics at future colliders (e+e- linear collider, ...) Does the Higgs unitarize the Standard Model (vector boson scattering, ...)? Non-Higgs searches for new physics at the LHC (top sector, SUSY, ...) | |

Contents: | n the field of physics, computational tools are widely employed as for the analysis of experimental data as well for the description and simulation of physical systems. The motivation to use computational tools is to explore the complex physical world better than otherwise possible with analytical tools. The seminar will cover some of the most commonly used computational methods to simulate physical phenomena. Each student is suppose to understand an algorithm, to apply it to a physical situation mostly from quantum physics and to present the results in a presentation. The subjects will reach from: * Time-evolution of Schrödinger equations (e.g. Runge-Kutta and Crank-Nicolson, split step methods). Physical examples are two-level atoms excited by a light field, a single particle moving in a time-dependent external potential, or the evolution of a Bose-Einstein condensate after an excitation. * Variational methods and exact solutions for quantum many body systems The solution of eigenvalue problems lies at the heart of the description of quantum mechanical systems. We will introduce the variational principle and show how this can be applied to describe, e.g., the hydrogen atom. More complicated variational ansaetze as the Gutzwiller ansatz, for bosonic atoms in a periodic potential can be introduced and the quantum phase transition between a superfluid and a Mott-insulator demonstrated. This is an example of the attractive field of ultracold quantum gases. * Quantum Monte-Carlo methods Stochastic methods as the quantum Monte-Carlo method are indispensable to treat systems with a large number of coupled degrees of freedom. Examples are the simulation of quantum gases or classical spin systems. Thereby we focus the discussion on critical phenomena and the calculation of statistical averages. | |
