Cryogen-free high-temperature superconductor undulator structure and method for manufacturing the same

A superconductor undulator module, comprising:

• an upper magnetic core body having a first half upper magnetic pole array and a second half upper magnetic pole array vertically aligned to the first half upper magnetic pole array;
• a coil structure wound on the upper magnetic core body;
• a metal plate set sandwiched by the first half upper magnetic pole array and the second half upper magnetic pole array, and a portion of the coil structure is sandwiched by two metal plates of the metal plate set;
• and
• a lower magnetic core body in proximity to a bottom of the upper magnetic core body.

A method of manufacturing a superconductor undulator structure, the method comprising:

• forming a plurality of coil units, each of the coil units comprises two first superconductor tapes attached to two edges of a second superconductor tape, respectively;
• sandwiching the plurality of coil units by a metal plate set, wherein each of the first superconductor tapes outwardly extends from a side of the metal plate set;
• receiving a magnetic core body comprising a first half magnetic pole array and a second half magnetic pole array vertically aligned to the first half magnetic pole array;
• disposing the metal plate set between the first half magnetic pole array and the second half magnetic pole array;
• and
• winding the first superconductor tapes on the magnetic core body.
