چکیده انگلیسی
⺠We developed an equipment to coat photoemissive material on a small area of a cathode tip for TEM in high vacuum and to detect photoelectrons from coated material. ⺠Cs3Sb emitting photoelectrons was formed at â20 °C from the layers of Sb, Cs and Sb which were deposited on a cathode tip at â20 °C with the developed equipment. ⺠Lifetime tests of Cs3Sb photocathode were performed at â20 °C and 11 °C. ⺠The effects of vacuum level, temperature and anode voltage on photoemission from Cs3Sb were also examined.
