The L3 experiment at the Large Electron-Positron collider at CERN was one of
the largest in the high energy physics. PNPI made a significant contribution to the L3 experimental complex. A half of the electromagnetic calorimeter crystals were fabricated by joint efforts using the material supplied by PNPI, the muon spectrometer high-voltage monitor was designed, produced and installed by the PNPI group. All the L3 data taking and experimental control electronics (about 1000 CAMAC and FASTBUS crates) were installed in the water-cooled racks (250 racks) designed (jointly with CERN) and fabricated at PNPI. Finally, the forward-backward FTC detectors, together with the electronics, have been designed and produced at PNPI. The PNPI physicists performed the FTC exploitation, including its calibration and alignment. The PNPI group participated in the data taking and the analysis of the data collected. More than 100 papers were published by the L3 collaboration. One of the main results of the L3 experiment was the high precision confirmation of the validity of the Standard
Model.
