We describe the R&D effort to define the design parameters, method of construction and experimental results of single-electron wire detectors. These detectors will be used for particle identification using Cherenkov ring-imaging techniques in the SLD experiment at SLAC. We present measurements of pulse heights for several gases as a function of gas gain, charge division performance on a single-electron signal using both 7 and 33 μm diameter carbon wires, photon feedback in TMAE-laden gas, average pulse shape, and its comparison with the predicted shape and cross-talk. In addition, we present results of wire aging tests and other tests associated with construction of this unusual type of wire chamber.
