Ion irradiation with Xe+ has been utilized to produce electrical condu
ctivity in PMMA, as measured using a four-point in-line probe. Inciden
t ion beam energy and current density have been varied to investigate
their effect on electrical conductivity and optical absorbance of the
samples after irradiation. Results support the premise that selection
of beam parameters that maximize the ratio of energy transfer-producin
g displacements to energy transfer-producing ionization maximizes the
ratio of induced conductivity to induced absorbance in the irradiated
samples. Conductivity versus ion dose has also been shown to be well e
stimated using a damage trail model. (C) 1994 John Wiley and Sons, Inc
