      abstract     = {A new method for the experimental study of ionization loss
                      of relativistic negatively charged particles moving in a
                      crystal in the channeling regime using a semiconductor
                      surface-barrier detector with smoothly tunable thickness of
                      the depleted layer is proposed. The thickness of the
                      depleted layer in a flat semiconductor detector can be
                      smoothly regulated by the value of the bias voltage applied
                      to the detector. Therefore, the energy distribution of the
                      ionization loss of relativistic particles which cross the
                      detector and move in the channeling regime in the detector
                      crystal can be measured along the path of the particles by
                      varying the bias voltage of the detector and the
                      dechanneling length can be found. Available literature data
                      on experimental and theoretical researches of the
                      dechanneling length are reviewed. The significant
                      disagreement between the experimental and theoretical data
                      is noted. Comparison of experimental data obtained by the
                      detector-target with smoothly tunable thickness of the
                      depleted layer with calculations can help to develop
                      theoretical description of the dynamics of motion of
                      negatively charged particles channeling in a crystal. A
                      better understanding of the dechanneling length properties
                      can be useful in the production of positrons and other
                      particles such as neutrons by an electron beam in crystals,
                      as well as in the development of crystalline undulators, and
                      in the crystal-based extraction of electron beams from a
                      synchrotron.},
