Method for manufacturing a HTS coated tape with laser beam cutting

摘要

A method for manufacturing a high temperature superconductor (=HTS) coated tape (20), with the following steps: preparation of a substrate tape (1), deposition of at least one buffer layer (2), deposition of an HTS film (3), deposition of a metallic protection layer (35) on the HTS film (3) and deposition of a metallic shunt layer (36) is characterized in that, prior to deposition of the metallic shunt layer (36), the partially prepared coated tape (10) undergoes a laser beam cutting in order to provide a desired tape form, wherein the laser beam cutting is applied together with a gas flow and/or a liquid flow (23). The method reduces the loss of critical current and reduces or avoids a deterioration of the critical temperature in a HTS coated tape due to tape cutting.

1. A method for manufacturing a high temperature superconductor (=HTS) coated tape, the method comprising the steps of:
a) preparing a substrate tape; b) depositing at least one buffer layer onto the substrate tape; c) depositing an HTS film onto the at least one buffer layer; d) depositing a metallic protection layer onto the HTS film; e) depositing a metallic shunt layer; and f) cutting, prior to step e), a partially prepared coated tape using laser beam cutting to provide a desired tape form, wherein the laser beam cutting is applied together with a gas or liquid flow.
