[en] A single-point Thomson scattering diagnostic is used to determine the electron temperature T_e of field-reversed-configuration (FRC) compact toroids generated in the θ-pinch source of the Los Alamos FRX-C/LSM experiment. Measurements are performed close to the axial midplane and near the magnetic and geometric axes. A broad range of plasma conditions is investigated and electron temperatures vary, on average, between 90 and 190 eV. For a given condition, T_e remains relatively constant during the 60 μs measurement interval between formation and the onset of the n = 2 rotational instability. T_e increases with plasma diameter and external magnetic field, and decreases slightly with fill pressure. The temperature at the geometric axis is consistently 10--20% lower than that near the field null. The temperature is approximately 35% higher than observed previously on the smaller FRX-C device. The implications of these measurements on plasma confinement properties are discussed. 25 refs., 18 figs., 8 tabs
