SIMULATION STUDIES OF LASER COOLING FOR THE GAMMA FACTORY PROOF-OF-PRINCIPLE EXPERIMENT AT THE CERN SPS

The Gamma Factory proof-of-principle (GF PoP) experi- ment at the Super Proton Synchrotron (SPS) at CERN aims at demonstrating laser cooling of high energy Li-like Pb79+ in a synchrotron. First, we present laser cooling simula- tions with realistic laser and beam parameters of the GF PoP experiment at the SPS. Furthermore, we investigate the ex- pected cooling performance for a Fourier-limited laser pulse and compute the performance metrics, such as emittance reduction. These metrics are then compared to intra-beam scattering (IBS) growth rates to determine the cooling fea- sibility. Lastly, the angular spread of the outgoing gamma rays is investigated.
