Electric field and drift characteristics studies for the multiwire chambers of the third plane of HADES

The aim of this report is a brief presentation of the physics motivation that lies behind the HADES project, and in more detail, the description of the main features of the spectrometer. More explicitly, it will deal with the operational features of the drift chambers which are incorporated in the experimental setup. The studies of the working characteristics and the simulations aimed to optimize the performance of the drift chambers are also described. Finally mentioned are the conclusions of these simulations and the proposals that will indeed lead to the optimization of the operation of the drift chambers.
