Query: Characteristics of proportional counter filled with CF$_4$ and Xe
  additions   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.
