The primary objectives were the development of a linear quadrupole ion trap (LQT) and a time-of-flight (TOF) mass spectrometer. The LQT functions by forcing ions into a stable trajectory controlled by radio-frequency electric fields. A general overview of the development and operation of the LQT will be discussed. The ions that are currently being studied are produced by laser ablation which produces a plume of multiple different molecules. In order to identify trapped ions, a TOF mass spectrometer was developed and assembled. The ions are radially extracted from the LQT with a particular energy and accelerated through the drift tube. By measuring the TOF, the mass of the ions can be determined. Further discussion of the TOF device and other projects will follow.
