[en] The heart of each time-of-flight neutron scattering instrument is its complement of detectors and the associated encoding and counting electronics. Currently there are ten fully-scheduled neutron scattering instruments in operation at IPNS, with three more instruments under development. Six of these instruments use position-sensitive neutron detectors (PSDs) of various types. These PSDs include a 30 cm x 30 cm, ∼3 mm resolution, neutron Anger camera area PSD with ⁶Li-glass scintillator; a 2.5 cm dia, ∼0.7 mm resolution, microchannel-plate area PSD with ⁶Li-glass scintillator; a 20 cm x 20 cm, ∼5 mm resolution, ³He proportional counter area PSD; a 40 cm x 40 cm, ∼4 mm resolution, ³He proportional counter area PSD; a flat 25 cm long, ∼1.6 mm resolution, ³He proportional counter linear PSD; and 160 cylindrical ³He proportional counter linear PSDs, each of which is 1.27 cm in dia and 60 cm long and has ∼14 mm resolution. In addition to these PSDs, ∼750 standard cylindrical ³He proportional counters of various sizes are utilized on IPNS instruments, and ∼20 BF₃ pulsed ion chambers are in use as beam monitors. This paper discusses these various detectors and associated electronics, with emphasis on the instrumental specifications and the reasons for the selection of the different types of detectors. Observed performance of these detectors is also discussed. 19 refs., 5 figs., 2 tabs
