Characterization of the Xenon-10 Dark Matter Detector with regard to electric field and light response

Electrostatic and Monte Carlo Simulations of the Xenon-10 Dark Matter Detector were carried out. Electrostatic simulations led to optimization of the charge sensitive region through proper determination of resistor chain values for the field shaping wires and through maximization of the charge sensitive region by reducing areas of charge loss. These simulations also led to identification of problem regions which would otherwise hindered detector calibration and data analysis. Monte Carlo simulations of the light response for both primary and secondary scintillation light were instrumental in position reconstruction in the gas phase of the detector and in the identification of events occurring inside the problem regions found in the electrostatic simulations. Data comparison with Activated Xenon (131Xe) with its gamma ray feature at 164 keV and isotropic event distribution showed good agreement with simulated data.
