Abstract

An improved calibration technique based on a radio-frequency-quadrupole (RFQ) accelerator is presented. A high-intensity flux of 17.6MeV photons, produced by radiative capture of 1.85MeV protons from the RFQ in a lithium target, is used to calibrate in situ 11000 crystals of the L3 BGO calorimeter. We present results obtained for the calibration of 1997-1999 L3 data samples. For the first time a calibration precision better than 0.5% is reached for the entire BGO calorimeter. The importance of such a technique is also outlined in view of extensive use of crystal calorimetry at the LHC.
