A small, 10 x 10 cm/sup 2/, parallel plate avalanche counter has been tested paying special attention to those features which can be important in the Time Projection Chamber. The structure of the test chamber is shown. It has a conversion and drift volume, 11 mm thick, delimited by two stainless steel cross wire grids, of 100 ..mu..m wire diameter and 500 ..mu..mm pitch, identified by HV1 and HV2. The anode is made of thick wires, 100 ..mu..m in diameter spaced every 500 ..mu..m. The amplification gap is 4 mm thick. Below the anode, 1 mm apart, we have paced an identical wire plane, HV4, with wires perpendicular to the anode wires. Both electrodes are equipped with electronics and read out. All measurements were performed with a mixture of argon and methane (83% - 17%), a typical gas for Time Projection Chambers. A multiplication factor up to 10/sup 5/ was attained.
