  A possible implementation of the Micro Drift Chamber (MDC) technique as a
high resolution vertex detector in the upstream part of the DIRAC spectrometer
was investigated in this paper. Simulations of different MDC layout were
performed with the help of GARFIELD package. Based on the results of simulation
the optimal chamber geometry and the gas mixture were selected.
  One cell prototype was produced and its characteristics were measured at
different particle fluxes, various gas pressures and thresholds of electronics.
  Data observed together with expected coordinate resolution of MDC allow to
employ such detector in different field of application including the DIRAC
experiment.
