Low emittance machines require lattices with many magnets of short length. Furthermore, successful lattices require strong gradients with strong dipole fields. These lattices are popular today, as MAX IV has demonstrated that a diffraction limited synchrotron light source can be based on such a lattice. This paper gives an overview of the various magnets used by the various diffraction limited lig...Show More
Nuclotron-Type Cables: From Fast Ramped Sc. Magnets to Multipurpose Application
Egbert Fischer;Kei Sugita;Pierre Schnizer;Hamlet Khodzhibagiyan
In the 1990s, for Nuclotron, the pioneer accelerator using fast ramped superconducting magnets, a novel cable with superconducting strands wrapped around a cooling tube was developed. Such cable fabrication technology was advanced and adopted for the SIS100 or NICA project. In parallel with major application for fast ramped superferric magnets, application for high field magnets with a cosine-thet...Show More
