“…The coil design is based on Kapton insulated flattened SSC Rutherford cable (wound in a traditional saddle configuration) that provides a large current margin, and commercially available fiberglass pre-preg epoxy tape. The superconducting cable has been re-rolled to remove the 0.9 o keystone angle with only an approximate 1% loss of short sample performance after re-rolling [6]. The installation of the coils within the helium vessel and the subsequent vessel closure welds were carefully controlled processes utilizing a multi-step checking procedure to minimize distortions due to welding.…”

Jefferson Laboratory is embarked on an energy upgrade to its flagship continuous electron beam accelerator in order to expand the scope of its research capabilities and probe further into the structure of nuclear particles. The 12 GeV upgrade includes the design, manufacture, integration, installation and commissioning of eight different superconducting magnets in three separate experimental halls. The effort involves other national laboratories, universities and industry spanning three countries. This paper will summarize the key characteristics of these magnets, ranging in size from 0.2 to 23 MJ in stored energy, and featuring many different types and configurations. The paper will also give an overview of the specific technical challenges for each magnet, and a status report on magnet manufacture and expected delivery dates. The 12GeV upgrade at J-Lab represents the largest superconducting magnet fabrication and installation program currently ongoing in the United States and this paper will present the breadth of collaborations supporting it.  Index Terms-12 GeV upgrade, continuous electron beam accelerator, superconducting magnets, Jefferson Lab Manuscript received August 08, 2014.
