Description

Production of low-emittance electron bunch from a photocathode RF-Gun has been developed in Waseda University. The characteristics of Electron beam is mostly determined by a parameter of UV laser. In this paper, we improve the spot form of UV laser on cathode to generate a lower emittance electron beam. It was done by changing the injection form of UV laser. And then transverse emittance of improved electron beam was measured by double slits scan technique which was developed in this laboratory. As a result of changing the injection form, transverse emittance was reached about 3 πmm mrad. This value is about half of previous results. (author)
