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,
Heike Hanada have to be made concerning what is to be demolished and how one can or should adapt oneself when building. It is a tricky balancing act in which conservative conclusions come easily. When a new building stands next to an old one, the difference in periods is made articulate, the new enriches the old and vice versa, resulting in a powerful wholeness. The extension has officially been put on hold in autumn 2009 after a change in local government and a massive campaign about what critics saw as an unacceptable impact on the original, Asplund approved complex.
