The purpose of this project is to develop a new class of XPS and PEEM which can detect the interface structure contacting the liquid phase, which has been impossible for a long time. We have produced a cell window which can allow the transmission of electron.We carried out(1) The electron trajectory calculation in the window. (2) The production of electron transmission window (3) Remodeling the PEEM system(4) Liquid measurement cellWe have successfully developed liquid measurement cell with electron transmission window. We obtain the PEEM image using electron transmission window. We have improved the PEEM with electromagnetic lens system to detect insulator samples and to set aperture accurately at the focal point to reduce the danger for the leakage accident. Consequently we got an image of Pt in the presence of water.
