Temperature dependence of dissociative electron attachment to methylene chloride in the electron energy range of 0{endash}10 eV was studied in a high-temperature electron swarm apparatus. The measurements were made using N{sub 2} and Ar as buffer gases. From the measured electron attachment rate constants, the electron attachment cross sections at 300, 400, and 500 K were determined using an unfolding technique. The maximum electron attachment cross sections at 300, 400, and 500 K were {approx}3.1{times}10{sup {minus}18}, {approx}8.2{times}10{sup {minus}18}, and {approx}1.7{times}10{sup {minus}17} cm{sup 2}, and occurred at electron energies of {approx}0.8, {approx}0.65, and {approx}0.55 eV, respectively. The increase in electron attachment to methylene chloride with temperature is attributed to the increase in the vibrational energy of the molecule. {copyright} {ital 1999 American Institute of Physics.}
