Perfluorocyclobutane (c-C4F8) is one of the most promising gases to be used in gas mixtures, which are the candidates to substitute for SF6 gas as high dielectric strength insulators with a reduced potential for global warming. The set of initial collision cross-sections are assembled and modified. The motion of electrons in c-C4F8 in uniform electric fields is simulated using Monte Carlo method. Also the density-normalized ionization coefficients α/N, attachment coefficients η/N, the effective ionization coefficients (α – η)/N, drift velocity (Ve) and the electron longitudinal diffusion coefficient (NDL) are calculated for the range of density-reduced electric field strength, 300 E/N 1000 Td. The electron swarm parameters of simulation are compared with experimental data and other results of simulation, which obtain a good agreement. However, further calculations and measurements for c-C4F8, such as η/N and NDL are required.
