Dynamo and Hydromagnetic LiquidMetal Experiments
Magnetic dynamo experiments are being performed in many laboratories throughout the world. The most successful have been at Kalsruhe and Riga where liquid sodium has been forced in constrained flows and produced predicted postive dynamo gain. The unconstrained flows are being investigated at Wisconsin, Cadarache , and Maryland. These experiments have not reached the critical values of the magne...
متن کاملThe α Dynamo Effects in Laboratory Plasmas
A concise review of observations of the α dynamo effect in laboratory plasmas is given. Unlike many astrophysical systems, the laboratory pinch plasmas are driven magnetically. When the system is overdriven, the resultant instabilities cause magnetic and flow fields to fluctuate, and their correlation induces electromotive forces along the mean magnetic field. This α-effect drives mean parallel...
متن کاملThermal-Blooming Laboratory Experiments
• We conducted a multiphase series of laboratory experiments to explore the adaptive optics compensation of a laser beam distorted by strong thermal blooming. Our experimental approach was to create on a small, low-power beam the same phase distortion that would be experienced by a large, high-power beam propagating through the atmosphere and to apply phase compensation via deformable mirrors. ...
متن کاملHistory and results of the Riga dynamo experiments
On 11 November 1999, a self-exciting magnetic eigenfield was detected for the first time in the Riga liquid sodium dynamo experiment. We report on the long history leading to this event, and on the subsequent experimental campaigns which provided a wealth of data on the kinematic and the saturated regime of this dynamo. The present state of the theoretical understanding of both regimes is delin...
متن کاملDynamo: real-time experiments with multiple mobile robots
In the Dynamo project at UBC, we have developed an extensible facility for experimental mobile robotics. It currently consists of nine radio-controlled mobile robots, two CCD colour video cameras, a video transmitter and tuner, radio controllers, Datacube image processing hardware, and a network of transputers. Software for tracking, control, and simulation has also been developed. Ongoing proj...
