A study is made of the ion current in a discharge of the Penning type using a cooled cathode, with a collector consisting of concentric rings, mutually insulated, located in the space behind one of the cathodes, in the center of which there is a hole. The electron current passing through the cathode and incident on a Faraday cylinder placed beyond it is also investigated. Energy distribution curves are given for the ions and electrons in the discharge for different parameters.
