Dendritic flux avalanches in a superconducting MgB2 tape

Autor: Qureishy, Thomas, Laliena, Carlos, Martínez, Elena, Qviller, Atle Jorstad, Vestgården, Jørn Inge, Johansen, Tom Henning, Navarro, Rafael, Mikheenko, Pavlo

MgB2 tapes with high critical current have a significant technological potential, but can experience operational breakdown due to thermomagnetic instability. Using magneto-optical imaging the spatial structure of the thermomagnetic avalanches has bee

The submicrosecond dynamics of thermomagnetic avalanches in superconducting films with nonconducting holes (antidots) is considered.When such an avalanche reaches a hole, it is quickly filled with magnetic flux, and often its rim becomes unstable and

It is demonstrated that circular holes in superconducting films of Nb can arrest the propagation of thermomagnetic avalanches. The effect was found over a range of temperatures where the material is susceptible to this instability. For other hole sha
