Nine coaxial cables which have been proposed or are presently being used for carrying the currents generated in ionization chambers have been critically studied with reference to their suitability to this application. Included in this study are four low-noise triaxial cables, three low-noise two-conductor cables, and two of other types of cables. For each cable the following characteristics were determined: inherent noise currents, currents produced by cable movements, polarization currents, the degree of electrostatic shielding of the central signal-carrying conductor, and radiation induced cable currents. This study indicates that two low-noise triaxial cables, both employing Teflon dielectric surrounding the central conductor, offer the best overall performance for use with ionization chambers.
