The cylindrical Hall thruster (CHT) having lower surface-to-volume ratio which exhibited performance comparable with conventional annular Hall thruster were investigated. The plasma potential, ion density and electron temperature profiles were measured using slow movable emissive and biased Langmuir probes inside the 2.6 cm CHT. The potential drop was localized mainly in cylindrical part of CHT which suggest that thruster suffer lower erosion of channel walls due to fast ion bombardment. The distribution of plasma density in cylindrical part of channel at thruster axis was (2.6-3.8)×10 12 cm -3 and maximum electron temperature was 21eV at discharge voltage of 300V.
