Emittance growth from luminosity burn-off in future hadron colliders

Future hadron colliders aim at producing larger integrated luminosities by burning-off an increased fraction of the bunch particles. This burn-off removes particles unevenly in the bunch distribution generating an emittance growth. Analytical equations are derived describing the bunch distribution s...

description Future hadron colliders aim at producing larger integrated luminosities by burning-off an increased fraction of the bunch particles. This burn-off removes particles unevenly in the bunch distribution generating an emittance growth. Analytical equations are derived describing the bunch distribution suffering luminosity burn-off and cooling from synchrotron radiation damping, far from the equilibrium emittance, and possibly including transverse collision offsets. This effect is evaluated for HL-LHC [G. Apollinari , Report No. CERN-2017-007-M, 2017], HE-LHC [A. Abada , Eur. Phys. J. Spec. Top. 228, 1109 (2019)EPJSAC1951-635510.1140/epjst/e2019-900088-6], and FCC-hh [A. Abada , Eur. Phys. J. Spec. Top. 228, 755 (2019)EPJSAC1951-635510.1140/epjst/e2019-900087-0.] and included into a step-by-step simulation of the physics fill, together with intrabeam scattering, to evaluate impact on performance.
