Lawrence Berkeley National Laboratory is involved in a number of scientific programs that benefit significantly from developments in superconducting magnet technology. Here we will discuss two very active areas of research. First, we will describe the motivation for the development of superconducting undulators (SCU’s) for free-electron lasers, and outline our ongoing research program to develop a robust SCU technology, addressing field performance, field quality and correction, and field-measurement issues. Second, we will describe the Superconducting Magnet Program (SMP) within the Accelerator and Fusion Research Division of LBNL. The SMP is a flagship program within the US DOE complex, devoted to superconducting accelerator magnet research and development for High Energy Physics needs. We will describe ongoing contributions to the US LARP program and to high-field dipole technology development.
