A particular kind of gaseous particle detector, called resistive plate counter, has been built and tested with cosmic rays. It is composed of two parallel highly resistive electrode plates between which circulates an ionizing gas, and of capacitively coupled readout pads. The tests look at the pulse shape, efficiency, charge distribution, time delay, and time resolution of the counter. It is shown that these characteristics are dependent upon the voltage applied to the electrodes, the gas mixture ratio (argon/butane/freon), and the surface irregularities of the electrodes. The counter exhibits a 98% efficiency and a time resolution of approximately 1 ns. These results are consistent with published results for this type of counter.
