Dynamics of cold and controlled molecules |
Speaker: | Melanie Schnell (Max Planck Advanced Study Group at the Center for Free Electron Laser Science, Hamburg & Max Planck Institut für Kernphysik, Heidelberg) |
Abstract: | During the last decade, many techniques have been developed to cool and manipulate molecules. Using optical, magnetic and electric fields, it had become possible to gain complete control over molecules in the gas phase and produce unique samples with a well-defined computer‐controlled velocity and velocity distribution, well-determined positions and quantum states. On the one hand, these samples are used to reach the ultracold regime and to study collective phenomena. On the other hand, they are ideally suited for applications such as studying cold collisions, performing precision studies to determine the time variation of fundamental constants and the effect due to parity violation in chiral molecules, and to study the intra- and intermolecular dynamics of such samples. In my talk, I will introduce the recent techniques to manipulate the motion of polar molecules with particular emphasis on Stark deceleration and trapping, and I discuss their applications in the above-mentioned fields. |

Time resolved measurement of automotive exhaust mass flow |
Speaker: | Dipl.-Ing. Katharina Doblhoff-Dier (Technische Universität Wien, Institut für Angewandte Physik) |
Abstract: | Exhaust gas regulations for automotive engines become increasingly strict. New ecological legislations have already set high demands to measurement technology. Time-resolved measurements of exhaust emission - including the mass flow rate - would provide a better basis for an optimization of the engine and allow even stricter laws.
This talk gives an overview on the issues connected with the time-resolved measurement of automotive exhaust mass flow. The focus is directed on measurement techniques using differential pressure devices. Encountered problems, such as flow and temperature pulsations, are discussed and possible solutions are explained. Results are presented from measurements performed on a flow bench and on an engine in a test bed.
