Bremsstrahlung from relativistic heavy ions in a fixed target experiment at the LHC

Understand

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 $Ze$ equal $208$ and $18$ respectively, these ions are accelerated to energies of $7$ TeV$\times Z $.
• The bremsstrahlung peaks around $\approx 100$ GeV and the spectrum exposes the nuclear structure of the incoming ion.
• The peak structure is significantly different from the flat power spectrum pertaining to a point charge.
