<span>The electron swarm parameters in gases are necessary for the simulations of plasma processes. The sulfur hexafluoride (SF6) has enormous applications suitability, because of its excellent dielectric properties, it is a gas used extensively as an insulating gas in various electric devices. Consequently, we must dedicate a significant attention to studying the physical properties of this gas. An investigation has brought into effect on the electron swarms parameters in SF6 gas in time varying electric fields using a Monte Carlo simulation. Swarm parameters as a function of instantaneous E/N (E is the electric field and N the gas number density of background gas molecules) for different dE/dt are determined.</span>
