Possible Accurate Time/Frequency Sources for Maserless VLBI? Seticon04
Possible accurate time/frequency sources for maserless VLBI? SETICon04 Marko Cebokli S57UUU ABSTRACT - The SETI League's project ARGUS currently works as a set of independent antennas/receivers, distributed in direction to maximize solid angle coverage. In some cases like wanting to do a follow-up observation with increased sensitivity, it would be desirable to coherently combine signals from several antennas. Since project ARGUS antennas are geographically dispersed, VLBI techniques will have to be used. This paper gives a quick overview of possible synchronization sources available to stations lacking atomic standards or masers. 1. REQUIREMENTS When combining two coherent signals of equal amplitude, to keep combining losses below 1dB, the phase error must be less than 54 degrees. This is similar to the common optical criterion of 1/8 wavelength or 45 degrees wavefront error. In terms of delay, for example on 1.4GHz, that is cca 100ps or 3cm of path length difference. For a 100 sec integration time, for example, the required accuracy is therefore 1E- 12. On lower frequencies, the requirement gets relaxed proportionally to wavelength, but VLBI gets difficult because of the random delays in the ionosphere, which quickly increase below a few hundred Mhz. Maybe some equivalent of adaptive optics as used by optical astronomers to mitigate atmospheric turbulence ('seeing') could be used here to take the twinkle out of the ionosphere on the lower bands? Apart from the RF frequency/phase synchronization, there is also the need to synchronize the recording start time, to reduce the amount of searching needed at the central correlating station. -

Dynamics and Control of Resistive Wall Modes with Magnetic Feedback Control Coils: Experiment and Theory

Katsuro-Hopkins, A. Klein, Y. Liu, D. A. Maurer, D. Maslovsky, G. A. Navratil, T. S. Pedersen, M. Shilov, and N. Stillits Department of Applied Physics and Applied Mathematics Columbia University, New York, NY 10027, USA e-mail contact of main author: [email protected] Abstract. Fundamental theory, experimental observations, and modeling of resistive wall mode (RWM) dynamics and active feedback control are reported. In the RWM, the plasma responds to and interacts with external current-carrying conductors. Although this response is complex, it is still possible to construct simple but accurate models for kink dynamics by combining separate determinations for the external currents, using the VALEN code, and for the plasma’s inductance matrix, using an MHD code such as DCON. These computations have been performed for wall-stabilized kink modes in the HBT-EP device, and they illustrate a remarkable feature of the theory: when the plasma’s inductance matrix is dominated by a single eigenmode and when the surrounding current-carrying structures are properly characterized, then the resonant kink response is represented by a small number of parameters. In HBT-EP, RWM dynamics are studied by programming quasi-static and rapid “phase-flip” changes of the external magnetic perturbation and directly measuring the plasma response as a function of kink stability and plasma rotation. The response evolves in time, is easily measured, and involves excitation of both the wall-stabilized kink and the RWM. -
Overview Release
Chicago Architecture Biennial’s Fourth Edition, The Available City Opens to the Public on Friday, September 17 CHICAGO (August 25, 2021) – The fourth edition of the Chicago Architecture Biennial (CAB) will open to the public on September 17, responding to an urban design framework that proposes connecting community residents, architects, and designers to develop and create spaces that reflect the needs of communities and neighborhoods. Over 80 contributors from more than 18 countries will respond to this framework through site-specific architectural projects, exhibitions, and programs across eight neighborhoods in Chicago and in the digital sphere. Curated by the Biennial’s 2021 Artistic Director—designer, researcher, and educator David Brown—The Available City will present projects and programs that ask and respond to the question of who gets to participate in the design of the city by exploring new perspectives and approaches to policies. The Available City illuminates the potential for immediate new possibilities, highlights improvisational organizers of the city, and underscores the exponential impact of small elements in aggregate. The Biennial is free and open to the public beginning on Friday, September 17. It will be on view at sites and in locations throughout the city, activated through in-person and online programming through December 18, 2021. Mayor Lori E. Lightfoot commented, “The Biennial always represents a remarkable time for our city, when residents, visitors, cultural organizations, and businesses come together to explore new ideas and potential for Chicago and cities worldwide. It is inspiring to see the projects and ideas developed by Chicago residents and the contributors highlighting the potential for vacant spaces. -
