caverns. The collaborations also invested enormous effort in testing representative
samples of the detectors in test beams at CERN and other accelerator laboratories
around the world. These test-beam campaigns not only verified that performance
criteria were met over the several years of production of detector components, but
also were used to prepare the calibration and alignment data for LHC operation. The
so-called large combined test-beam setups, which represented whole ‘slices’ of the
different detector layers of the final detectors, proved to be very important.
