  of thermal and cold neutrons [1] is created at the Institute for Nuclear 
 Research. The detector has an active area of 128 x 128 mm2 with double gas
  gap of 2 mm and a 10B converter. The input window is made of a thin alumi
 num layer (3mm) to prevent scattering and absorption of neutrons. The oper
 ation of the detector was studied using W-Be photoneutron source. The phot
 oneutron source (IN-LUE) was created on the base of industrial electron li
 nac LUE-8 operating at electron energy of 7 - 8 MeV\, tungsten electron-ga
 mma convertor\, photoneutron beryllium target and moderator of fast neutro
 ns. The detector is located at a distance of 6 m from the source at an ang
 le of 60 relative to the electron beam axis. The detector efficiency is es
 timated as ~3% at neutron wavelength λ = 1.82 Å and 6% at λ = 8 Å. The
  efficiency of the background detection was less than 0.001% of that for t
 hermal neutrons. The resulting pulse height resolution is 15% and the spat
 ial resolution is 2.5 mm for the X coordinate with gas mixture Ar + 25% CO
 2 + 0.3% CF3Br under standard conditions. The resistive charge-division re
 adout is applied to determine neutron position from pulse height values.\n
