description: The paper presents the results of detectors longevity study, that aimed to create a technique to increase the lifetime of multiwire proportional chambers from the medical proton beam profilometer at the C-1000 synchrocyclotron. It is studied a possibility of removing deposits from the anode wires by a non-invasive method by the training of the detectors at the gas discharge of a gas mixture of 20% CO2 + 80% CF4. The successful laboratory tests have been carried out with use of cylindrical proportional straw counters to study the repeatability of the non-invasive recovery method for aging detectors. The regimes are studied as well for the occurrence of a gas discharge providing the etching of the deposits on the surface of the anode wires. The obtained results have a universal character, and then this makes them applicable to various types of gas-discharge detectors, which are in use at the nuclear medicine, high-energy physics, and atomic nucleus physics.
