The multisphere spectrometer at Lawrence Berkeley Laboratory (LBL) is widely used for the determination of neutron spectra and other related quantities from various radiation sources. It has been employed to take measurements at different LBL accelerator facilities, i.e., near the SuperHILAC, the BEVALAC, and the 88-in. CYCLOTRON. It has also been used in the tunnel of the TEVATRON at Fermilab. This paper summarizes the procedures, methods, and results of these experiments with the multisphere spectrometer and shows the diversity of its applications and significance. The spectra are unfolded with a LOUHI code using Sanna's response function, which provides satisfactory results comparable to those obtained with other codes. The neutron scattering effect is important for the Bonner detectors. This scattering effect is also discussed briefly.
