Summary of Fermilab's Recycler Electron Cooler Operation and Studies
Fermilab's Recycler ring was used as a storage ring for accumulation and
subsequent manipulations of 8-GeV antiprotons destined for the Tevatron
collider. To satisfy these missions, a unique electron cooling system was
designed, developed and successfully implemented. The most important features
that distinguish the Recycler cooler from other existing electron coolers are
its relativistic energy (it employs a 4.3 MeV, 0.1 A DC electron beam), a weak
continuous longitudinal magnetic field in the cooling section (~100 G), and
lumped focusing elsewhere. With the termination of the collider operation at
Fermilab, the cooler operation was also terminated. In this article, we will
summarize the experience of commissioning, optimizing and running this unique
machine over the 6 years of its existence.Comment: 3 pp. 3rd International Particle Accelerator Conference (IPAC 2012)
