Using the pulsed Townsend method the electron swarm parameters have been measured for \furan~ in buffer gases Ar, N2 or CO2 with mixing ratios <1.2%. The measurements were performed in a novel Pulsed Townsend experiment that can operate with a high degree of automation. The evaluated parameters presented here are the effective ionization rate, the critical field strength, and the electron attachment parameters of c-C4F8O. A linear dependence between mixing ratio and the swarm parameters was found. This linear response has been used to derive a preliminary set of attachment cross sections for c-C4F8O.
