Abstract
A magnet coil system (1) has a first end section (19a) of an HTSL-tape conductor (4) located ahead of a first end (19) of an HTSL-tape conductor (4) and a first end section (20a) of an LTS wire (7) located prior to a first end (20) of the LTS wire (7) which are connected electrically but not in a superconducting way in a connecting section (17) along the length of the connecting section. The LTS wire (7) has a flat shape at least within the connecting section (17) and one side of the flat LTS wire (7) abutting the HTSL-tape conductor (4) and the connecting section (17) has a length of at least 5 m. The magnet coil system has an acceptably small residual ohmic resistance which is achieved by simple means.
Claims19
A magnet coil system, comprising:
- a first coil section, wound with a high temperature superconducting (=HTSL) tape conductor;
- a second coil section comprising a low temperature superconducting (=LTS) wire, wherein said HTSL-tape conductor and said LTS wire are electrically connected in series;
- and
- a wound up connecting section forming a joint between said HTSL-tape conductor and said LTS wire, wherein a first end section of said HTSL-tape conductor located ahead of a first end of said HTSL-tape conductor and a second end section of said LTS wire located prior to a second end of said LTS wire are connected electrically via an ohmic contact in said connecting section and along a length of said connecting section, said LTS wire having a flat shape within said connecting section, which abuts said HTSL-tape conductor, said connecting section thereby having a length of at least 5 m;
- the magnet coil system further comprising a further LTS wire, wherein said HTSL tape conductor forms a further joint to said further LTS wire at a third end section ahead of a third end of said HTSL tape conductor.
