Description
Particle loss due to the emission of single energetic beamstrahlung photons is shown to impose a fundamental limit on storage ring luminosities at energies more than 2E~140 GeV for head-on collisions and 2E~40 GeV for crab-waist collisions. Above these thresholds the suppression factor due to beamstrahlung scales as 1/E^4/3 and for a fixed power of synchrotron radiation L \propto R/E^13/3. For 2E>150 GeV both collisions schemes have a similar limits on the luminosity. The attainable luminosities at the Higgs factory energy 2E=240 GeV at storage rings and linear colliders (LC) are comparable and LC is preferable for higher energy.
