Mass spectrometer |
摘要 |
Heavy ions are ejected earlier than light ions sequentially at almost zero energy and they are accelerated at a fixed voltage so as to be guided to a pusher of a TOF spectrometer. After ions are ejected in a procedure of giving an electric field gradient to an ion trap and linearly decreasing its RF voltage, a condition of spatially focusing ions having all mass numbers of a single point on the pusher is found. The focused ions are vertically accelerated using the pusher to perform the TOF mass spectrometry.
