The charge deposition dependence and energy loss in the transmission of electrons through insulating polyethylene terephthalate (PET) were studied for incident energies of 500 and 800 eV. Charge evolution at the sample tilt angles 蠄 = 0.0掳 and 鈭?.7掳 was investigated. After an initial quiescent period transmission was observed and found to reach equilibrium rather quickly. Inelastic behavior of the transmitted electrons was observed during the initial transmission as well as after reaching equilibrium for 蠄 = 鈭?.7掳 for both incident energies.
