Bremsstrahlung from relativistic heavy ions in a fixed target experiment at the LHC
Rune E. Mikkelsen, Allan H. Sørensen, Ulrik I. Uggerhøj
We calculate the emission of bremsstrahlung from lead and argon ions in A Fixed Target ExpeRiment (AFTER) that uses the LHC beams. With nuclear charges of equal and …
