| Abstract: | One home-made laser reflectron time-of-flight mass spectrometer was reported. The main features including its mechanics, principle, vacuum system, detector and operating system were introduced. The test experiments showed that the LA/MB(Laser Ablation and Molecular Beam) sourse could produce abundant cluster ions, the mass resolution of the R-TOF was nearly 2000 and the mass gate could work properly. It has been used to study clusters, some primary results were also listed. |
