Description

technical field [0001] The invention belongs to a high-voltage pulse generating device, in particular to a nanosecond rising-edge high-voltage pulse generating device in a Rydberg state field ionization experiment. Background technique [0002] In the fields of laser ionization spectroscopy and laser mass spectrometry, the core is the resonance between laser and particles and converting them into ions. For some atoms, other laser resonance ionization methods are difficult to achieve a high ionization rate, and the Rydberg state field ionization is an effective way to obtain a high ionization rate. For example, the self-ionization state of alkali metal atoms is difficult to use, and the cross-section through the continuous state ionization is extremely small, so the field ionization of the Rydberg state is the most effective way in its laser resonance ionization. [0003] The field ionization of the Rydberg state refers to the use of laser to excite the particle resonance to...
