Detection of a flow induced magnetic field eigenmode in the Riga dynamo facility

Phys. Rev. Lett. 84, 4365-4368, 2000 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 propeller rotation rate, additional measurements showed a slow decay of this mode. The mea...

Beschreibung
Zusammenfassung:	Phys. Rev. Lett. 84, 4365-4368, 2000 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 propeller rotation rate, additional measurements showed a slow decay of this mode. The measured results correspond satisfactory with numerical predictions for the growth rates and frequencies.
