摘要
本文报道了国内首台用于研究分子团簇的串级飞行时间质谱仪的研制过程.内容包括:串级飞行时间质谱仪的结构、原理、真空系统、检测控制系统、性能测试以及提高系统分辨率的措施等.并给出了用该装置所获得的碳原子簇正负离子的分布和硫原子簇的分布及S_5^+离子激光裂解等实验结果.
The building up of a tandem time-of-flight mass spectrometer for cluster studies has been reported. The main features of this system including the experimental arrangement, vacuum system, detection and operating systems have been disscused. Some experimental results obtained by this system including the mass distribution of positive and negative carbon cluster ions, and the UV photofragments of S_5^+ cluster are also reported.
