Quasi-Real Compton Scattering at Dafne for a Continuous Calibration of the Kloe Detector

Key Points

The aim is to explore the application of quasi-real Compton scattering for continuous calibration of the KLOE detector at DAFNE.
Reviewed quasi-real Compton scattering as a calibration technique.
Assessed its performance at DAFNE's energy range.
Evaluated data collection over the full angular range.
Quasi-real Compton scattering can produce very high event rates at DAFNE.
This technique allows continuous, efficient calibration of the KLOE detector.
Full angular coverage enhances calibration accuracy.

Abstract

Quasi-real Compton scattering, previously used in e^+e^- and e p collisions for luminosity measurements and detector calibration at PEP and HERA, is discussed for the energy range available at the construenda ϕ -factory DAFNE. We show that the very high rate expected at DAFNE makes this process particularly convenient for a contiuous calibration of the KLOE detector over the full angular range, directly from the data.
