Abstract
A simple and reliable method for determining the concentration of SF6 in an accelerator gas mixture with N-2 and CO2 is described. The techn ique makes use of the low velocity of sound in SF6 (approximately 1/3 that of air). The sound velocity of the mixture is determined by measu ring the spacing of acoustic resonances in a tube filled with the gas. Data from standard gas mixtures containing 0-10% SF6 are presented, s howing that the technique is accurate to approximately 0.5% absolute.
