| Research Abstract |
(1) A time-resolved electron energy analyzer was developed. The analyzer consists of an electrostatic ellipsoidal mirror analyzer and a charged particle streak-camera and exhibits excellent performance compromising between wide acceptance angle and good time resolution. We have developed new fabrication process of non-spherical grid system and quadrupole electrostatic lens system. The time and energy resolution of the spectrometer is 20 ps and 10eV,respectively.
(2) Measurement of time-resolved electron spectroscopy on solid surfaces was done in two ways. One is a measurement of internal conversion electron emission under nuclear resonant X-ray scattering. The experiment was made in an AR beamline of National Laboratory of High Energy Physics (KEK). The second one is a photoemission from solid surfaces by using VUV synchrotron radiation in the National Institute of Molecular Science.
(3) A picosecond photo-electron source was developed. The activation process of NEA GaAs photocathode was extensively studied. The annealing condition of GaAs single crystal plane was determined by using a scanning tunneling microscopy. The dependence of activation gas pressure and temperatures on step bunching phenomena was clarified.
