The construction of a three-coordinate proportional chamber with a 256 x 256 mm working region and with 1.0 and 2.0 mm spacing of the signal wires is described and its characteristics are presented. A charged-particle recording efficiency of 99% was achieved with the gas mixture Ar + 20% C4H10 + 2% C3H8O2 + 0.3% CF3Br. The plateau on the efficiency curve equaled 750 and greater than 1000 V and the spatial resolution equaled 0.318 and 0.67 mm for planes with spacings of 1 and 2 mm respectively. The effect of proportional chambers on the accuracy with which the coordinates of the vertices of the multitrack events were determined with a BIS-2 spectrometer was studied.
