Abstract: A half-liter two-phase xenon chamber was built and primary and secondary (proportional) scintillation signals were investigated by using α particles. The energy threshold in the chamber was less than 50 keV of electron equivalent and energy resolution was 18%. The value of the spatial (Z-coordinate) resolution achieved in the time projection chamber was about 0.4 mm.
