TL;DR: The COSY-11 installation as discussed by the authors is an internal experiment at the cooler synchrotron and storage ring at the Cosy Julich, which is designed for full geometrical acceptance close to threshold for meson production studies, especially in the 1 GeV/c2 mass range.

TL;DR: In this paper, the spin-flip cross-section of a low-energy electron-proton scattering was measured and the measured cross-sections are too small for making spin flip a viable tool in polarizing a stored beam.

TL;DR: The physics program of the SPARC collaboration at the Facility for Antiproton and Ion Research (FAIR) focuses on the study of collision phenomena in strong and even extreme electromagnetic fields and on the fundamental interactions between electrons and heavy nuclei up to bare uranium as discussed by the authors.
