| Outline of Final Research Achievements |
Development of the backside-excitation structure photocathode has been done. this photocathode consists of a transparent superconductor substrate and multi-alkali photoelectric surface. The transparent superconductor reflects RF and transmits excitation light. Superconducting properties and temperature dependence of quantum efficiency and initial emittance were measured. It was confirmed that it's possible to use for the superconducting RF gun.
