A detailed model of the Cornell Electron Storage Ring (CESR) guide field. including beam-beam interaction computed in the weak-strong regime. is the basis for a multiturn simulation of luminosity. The simulation reproduces the dependence of luminosity on bunch current that is measured in the storage ring. https://www.markbroyard.com/save-big-quest-mv40-gas-floor-fryer-40-lb-casters-natural-gas-discount-best-mega/
