イオン液体で濡らした針先端からのプロトン含有クラスターイオンビームの生成:集束イオンビーム(FIB)用の液体金属イオン源を参考として
Emission of cluster ions from a sharped rod wetted with liquid, which is an important phenomenon in liquid metal ion sources, was investigated using a protic ionic liquid. A stable cluster ion beam was generated from a tip of a sharpened rod wetted with propylammonium nitrate ([C3H7NH3][NO3]). The cluster ion beam contained massive cluster ions exceeding m/z 5000. In addition, the cluster ion beam was tested as a primary ion beam in secondary ion mass spectrometry (SIMS). The cluster ion beam proved to be useful for enhancing molecular ionization of organic materials.
