This research is conducted as a R&D work for the PHENIX experiment of the relativistic heavy ion collider (RHIC) at Brookhaven National Laboratory (BNL), in an effort to develop a multi-wire proportional chamber (MWPC) using a new pixel cathode pad readout method. The pads are formed by linking the pixels in a special pattern and the image charge signals on the pads are read by highly integrated CMOS digital electronic chips with chip-on-board (COB) technology. Two prototype pixel pad chambers, PC1 and PC3, were designed and constructed. The chambers were tested with high energy particle beams at BNL. This work demonstrates the feasibility and affordability of constructing and operating the pixel pad chambers with large number of channels, using the technology adopted here. Good spatial resolutions equal to about one-half the cell dimensions both along and perpendicular to the wire direction ($4mm$ for PC1 and $8mm$ for PC3) have been achieved. Charged particle track reconstruction efficiency and other chamber characteristics are also discussed.
