Anisotropy of electron temperature in a magnetized plasma is studied with the use of a cylindrical Langmuir probe, whose availability is investigated theoretically, and computer simulation is performed in comparison with the experimental results. It is found that the perpendicular electron temperature is possible to be measured by an ordinary cylindrical probe placed parallel to the magnetic field, while the parallel temperature by a plane probe placed perpendicular to the field. The theoretical treatments are based on the assumptions that the motion of electrons across the field is collision-dominated and he sheath width is much thinner than the probe radius. The experimental errors are found to be within 10% by estimating the various causes.
