摘要:
The present invention relates to an apparatus and method for measuring the critical current of a superconducting tape. A continuous critical current measurement apparatus for measuring critical current of a superconducting tape while feeding a superconducting tape in a liquid nitrogen container includes wheel-type current terminals and wheel-type voltage terminals. The superconducting tape is continuously supplied and fed by a reel-to-reel device, and the critical current of the superconducting tape is measured in real time using the wheel-type current terminals and the wheel-type voltage terminals while the superconducting tape is fed at constant linear velocity in contact with the wheel-type current terminals and the wheel-type voltage terminals. Accordingly, current is applied using wheel-type current terminals and voltage is measured using wheel-type voltage terminals while a superconducting tape is continuously supplied by a reel-to-reel device, thus continuously measuring critical current without burning out the superconducting tape.

The present invention is directed to a lamination method. The lamination method includes making the interior of a process chamber a vacuum, the process chamber including a first and a second metal sheet, supplying the first and the second metal sheets, injecting a bonding material between the first and the second metal sheets supplied, bonding the first and the second metal sheets with each other, and heating the bonded metal sheets. The first metal sheet is a superconductive tape, and the second metal sheet is stabilization metal tape.

The present invention is directed to a lamination apparatus and a lamination method using the same. The lamination apparatus includes a process chamber and a pump connected with one side of the process chamber for making the interior of the process chamber a vacuum. Inside the process chamber, a first and a second supply unit, an injection unit, and a bonding unit are provided. The first and the second supply units supply a first and a second metal sheet, respectively. The injection unit injects a bonding material between the first and the second metal sheets supplied, and the bonding unit bonds the first and the second metal sheets with each other. According to the present invention, a bonding force of the bonding material may be enhanced and various kinds of bonding materials may be used.

Provided is a method of forming a ceramic wire. In the method, a ceramic precursor film is deposited on a wire substrate. Then, the wire substrate on which the ceramic precursor film is deposited is treated by heating. For treating the wire substrate by heating, a temperature of the wire substrate and/or an oxygen partial pressure of the wire substrate are controlled such that the ceramic precursor film is in a liquid state and an epitaxy ceramic film is formed from the liquid ceramic precursor film on the wire substrate.
