Abstract :
The crab waist collision scheme has been successfully tested at the e+e− Frascati collider during the 2008–2009 runs: the gain in luminosity is consistent with the predictions while the background remains sustainable. Among the various inputs used by the DA Φ NE accelerator team to steer this new machine and improve its performances, key online information, absolute luminosity and background level measurements, has been provided by the LUMI detectors: a Bhabha calorimeter and two gamma bremsstrahlung proportional counters. This paper focuses on the results achieved with this experimental setup, described in details in another article.
