It measures large angle beamstrahlung in the visible range, providing both polarization and spectral information. The experience with the LABM during both Phase I and Phase II is reviewed. It is shown that large angle beamstrahlung has been observed, and beam parameters are preliminarly extracted from the measured yields. The measurements during beam-beam controlled oscillations are also discussed. PB - JACoW Publishing CP - Geneva, Switzerland ER -
