Magnetic Field Saturation in the Riga Dynamo Experiment
Agris Gailitis, Olgerts Lielausis, Ernests Platacis +7
After the dynamo experiment in November 1999 had shown magnetic field self-excitation in a spiraling liquid metal flow, in a second series of experiments emphasis was placed on the…
Detection of a flow induced magnetic field eigenmode in the Riga dynamo facility
Agris Gailitis, Olgerts Lielausis, Sergej Dement'ev +8
In an experiment at the Riga sodium dynamo facility, a slowly growing magnetic field eigenmode has been detected over a period of about 15 seconds. For a slightly decreased propell…
Magnetic field dynamos and magnetically triggered flow instabilities
Frank Stefani, Thomas Albrecht, Rainer Arlt +13
The project A2 of the LIMTECH Alliance aimed at a better understanding of those magnetohydrodynamic instabilities that are relevant for the generation and the action of cosmic magn…
History and results of the Riga dynamo experiments
Agris Gailitis, Gunter Gerbeth, Thomas Gundrum +3
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…
Magnetohydrodynamic experiments on cosmic magnetic fields
Frank Stefani, Agris Gailitis, Gunter Gerbeth
It is widely known that cosmic magnetic fields, i.e. the fields of planets, stars, and galaxies, are produced by the hydromagnetic dynamo effect in moving electrically conducting f…
Energy oscillations and a possible route to chaos in a modified Riga dynamo
Frank Stefani, Agris Gailitis, Gunter Gerbeth
Starting from the present version of the Riga dynamo experiment with its rotating magnetic eigenfield dominated by a single frequency we ask for those modifications of this set-up…
