Abstract:
1. A method comprising: feeding an uncoated substrate from a payout spool into a multi-chambered vacuum apparatus, the vacuum apparatus comprising plurality of deposition chambers defining an extended deposition zone, a multi-zone substrate heater located within the extended deposition zone, multiple high-temperature superconductor (HTS) targets located within and being arranged linearly along the extended deposition zone, the multiple HTS targets including a first HTS target and a second HTS target, the first HTS target comprising a HTS material and the second HTS target comprising said HTS material; translating the uncoated substrate along a translation path through the plurality of deposition chambers; impinging multiple laser beams simultaneously upon the multiple HTS targets and forming multiple overlapping plumes of HTS material within the extended deposition zone while imparting rotary and oscillatory motion to the multiple targets, wherein the multiple HTS targets oscillate in a direction parallel to the translation path; depositing HTS material on a first major surface of the uncoated substrate from the multiple overlapping plumes to provide a coated substrate; and winding the coated substrate onto a take-up spool.
