AGOR status report

Abstract

The AGOR-facility is now operating reliably with an availability approaching 90%. Past problems with beam transmission for high energy protons have been cured by repositioning the main coils. In conjunction with a fundamental physics programme requiring high intensity beams of heavy ions up to lead several development activities have been started.

Ultraperipheral Collisions at RHIC and the LHC

“…This was interpreted by STAR as being analogous to vacuum birefringence, only observed until now in astrophysical measurements. Similar polarization-driven effects are also observed in coherent ρ production, which is possibly sensitive to generalized TMD distributions in the nucleus [35].…”
