摘要： A method for depositing film on a substrate (16) through pulsed laser deposition, which includes: generating at least two pulsed laser beams (4, 5, 6) with at least one laser (1), and directing the at least two laser beams (4, 5, 6) to different target spots (9, 10, 11) of a target (12), whereby the target (12) is ablated and at least two plasma plumes (13) are created. The plasma plumes (13) create a flow of target material towards the substrate (16) and the target material is deposited onto the substrate (16) at a deposition area (24). The plasma plumes (13) created by the at least two laser beams (4, 5, 6) are spatially and temporally superimposed, and the target spots (9, 10, 11) are separated from each other at a distance that allows a gas-dynamical interaction of the created plasma plumes (13).

摘要： A method for operating a superconducting device (1; 1a, 1b), having a coated conductor (2) with a substrate (3) and a quenchable superconducting film (4), wherein the coated conductor (2) has a width W and a length L, is characterized in that 0.5≦L/W≦10, in particular 0.5≦L/W≦8, and that the coated conductor (2) has an engineering resistivity ρeng shunting the superconducting film (4) in a quenched state, with ρeng>2.5 Ω, wherein RIntShunt=ρeng*L/W, with RIntShunt: internal shunt resistance of the coated conductor (2). The risk of a burnout of a superconducting device in case of a quench in its superconducting film is thereby further reduced to such an extent that the device can be operated without use of an additional external shunt.

摘要： A superconducting structure (1) has a plurality of linked band-segments (2), with each linked band-segment (2) having a substrate (3) and a superconducting layer deposited onto it (4). The linked band-segments (2) are joined to one another by superconducting layers (4) that face each other. Each linked band-segment (2) is joined to two additional band-segments (7a, 7b) in such a way that the superconducting layers (4) of the two additional band-segments (7a, 7b) and of the linked band-segment (2) face each other. The additional band-segments (7a, 7b) together substantially overlap the total length (L) of the linked band-segment (2). This provides for a superconducting structure, which exhibits high superconductivity and which is very suitable for long distances.
