ACORDE (Altitude COsmic Ray DEtector) is a low-cost and lightweight particle detector. It will detect traces of cosmic rays with a cloud chamber, which will maintain a layer of supersaturated isopropyl alcohol vapour inside a pressurized container. A hot and cold spots, on its top and bottom, will make use of electronic heaters and dry ice, respectively. Particles crossing the
vapour layer will ionize the alcohol and the vapour will condense on these, leaving visible traces. These will be recorded with a set of cameras, whose images will be later processed with detection algorithms to study the amount and types of particles along the flight altitude.
