| Research Abstract |
A new x-ray spectrometer using the principle of a photoelectron spectroscopy method is developed for the purpose of the observations of plasma electron temperatures in the range of a hundred of eV.X-ray photoelectron spectroscopy (XPS) is a widely utilized method for surface-physics analyzes ; here, we employ a parallel-plate energy analyzer. This new type spectrometer is calibrated using synchrotron radiation from a 2.5-GeV positron storage ring at KEK.Theoretical calculations for photoelectron spectra from plasmas with various electron temperatures are carried out using the calibration data. This spectrometer is set up at the central cell of the GAMMA 10 tandem mirror for the measurements of potential-confined electron temperatures. Experimentally observed spectra are compared with the calculated spectra as well as the data from the other x-ray detectors.
