DESCRIPTION:Speakers: Vladimir Kazalov (INR RAS)\nHere we report the curre
 nt sensitivity of the large proportional counter to a $^{124}$Xe 2$\\nu$EC
 EC filled with xenon gas up to 5 atm. One of the main procedures for detec
 ting ECEC decays of $^{124}$Xe in an experiment using a gas target is iden
 tifying three charge ionization clusters released during the absorption of
  two X-ray quanta and Auger electrons from a daughter atom. The developed 
 new algorithm for digital processing of signals taken from the detector ma
 de it possible to consider the loss of electrons due to diffuseness and re
 combination in the track and correct the total energy release for the resp
 onse of a separate absorbed particle. Thus\, by increasing the efficiency 
 of selecting useful events\, we expect an increase in the sensitivity to t
 he half-life 2$\\nu$2K-mode for a 6-year run to $2×10^{22}$ y (at 90% C.L
 .) in the current experiment.\n\nhttps://indico.ific.uv.es/event/6178/cont
