| 英文摘要 | A He-jet laser time-of-flight (TOF) mass spectrometer system is built The sample atoms evaporated in the atomization chamber are used to simulate the reaction products. The sample atoms are transferred by helium gas trough a thin capillary. After passing through a skimmer, the sample atoms are formed into a neutral atom stream. A two-or three-color laser beams perpendicular to the atom jet is used to excite and ionize the atoms multi-steply. Then a pulsed electrical field pulls the ionized atoms to the TOF mass spectrometer. By this processing, the (Z,A) values of the sample atoms can be determined precisely. The efficiency of the spectrometer is studied by measuring the radioactivity of Na-24 atoms. The transmission efficiency consists of two parts, the transportation efficiency and the efficiency of laser resonance ionization. The transportation efficiency is determined to be about 17%. |
