2018年2月2日 · Abstract: Double disordered (DD) HTS layers processed via high-fluence PLD with modulated pressure and barium zirconate precipitation yield very high engineering current densities, above 900 and 600 A/mm 2 at 18 and 31 T, respectively, measured at 4.2 K and B||c.

2019年2月25日 · A multi-plume multi-turn pulsed laser deposition (PLD) system combined with the so-called 'radiation assisted conductive heater' has been proposed and further developed for REBCO layer deposition. Our effort was focused on minimizing the temperature variations in the deposition region by modifying the heating shield that assists the conductive ...

To overcome these problems we have designed and constructed an automated multitarget excimer pulsed laser deposition (PLD) system. We identify key elements of the system that can be utilised to address many of the problems currently encountered in HTS film growth.

Each divided 4 mm-wide HTS tapes by laser slitting have shown equivalent tensile properties. In the high field magnet, 2G HTS tapes are repeatedly subjected to tensile load by electromagnetic force. It is necessary to evaluate the fatigue characteristics of …

The development of High-Temperature Superconducting (HTS) thin-film technology has been significantly enhanced by the introduction of Pulsed-Laser Deposition (PLD). This technique excels in the deposition of multi-element compounds such as the high temperature...

2012年1月1日 · High temperature superconductor (HTS) wires and tapes have been an area of intense research, development and scaling up for manufacturing.
