Abstract: In this article the measurement results of proportional counter working characteristics filled with CF$_4$ and Xe ($0\div5$% Xe) additions at different pressures ($0.8\div14.8$ $at$) are presented. We have found that a bit of Xe addition reduces working voltage necessary to get the same gas amplification by two times against pure CF$_4$, it improves as well the resolution of the counter and increases limit gas amplification by more than ten times.<br />7 pages, 8 figures
