• The method of temperature measurement from Lyman sprung at 228Å is examined experimentally by using two sorts of helium plasmas. The electron temperature of the plasma produced by a theta pinch gun is estimated to be 23 eV at the time of the peak intensity of the continuum radiation. In the case of the plasma produced by a theta pinch machine, the electron temperature decreases from 37 eV at 2μs after the firing of the main bank of the machine to 21 eV at 3 μs. The latter results are compared with the results of the measurements of electron temperature by the method using light scattering of ruby laser beam. Both results agree within an experimental error of 20%.
