Superconducting magnet issues "shaken" out of them, until they are eventually able to operate reliably at their full planned current without experiencing quenches. Although the idea of making electromagnets with superconducting wire was proposed by Heike Kamerlingh Onnes shortly after he discovered superconductivity in 1911, a practical superconducting electromagnet had to await the discovery of superconducting materials that could support large critical supercurrent densities in high magnetic fields. The first successful superconducting magnet was built by G.B. Yntema in 1955 using niobium wire and achieved a field of 0.7 T at 4.2 K. Then, in 1961, J.E. Kunzler, E. Buehler, F.S.L. Hsu,
What We Did What We Did What We Did is a collaborative studio album by Swans frontman Michael Gira and Windsor for the Derby member Dan Matz. It was released on November 13, 2001 through Gira's Young God Records label. "What We Did" has a considerably more pop-oriented and accessible sound, compared to Gira's other solo works. The majority of the lyrics on the album was written by Matz. Allmusic critic Thom Jurek described the album as "a finely wrought album of relayed styles and layered textures enfolding one another into a music that could have only been made by these two men,
