Abstract

The invention discloses a nanosecond-level rising edge high voltage pulse generation device in a rydberg state field ionization experiment. The nanosecond-level rising edge high voltage pulse generation device comprises a power supply module, a switch module and an output load circuit, wherein the power supply module is connected with the switch module, and the switch module is connected with the output load circuit. The power supply module comprises a direct current stabilized power supply and an R1C1 filter circuit, and a number I power supply supplies power to the direct current stabilized power supply. The switch module comprises a quick high voltage pulse switch and an external trigger signal source, and a number II power supply supplies power to the quick high voltage pulse switch. The output load circuit is composed of a damping resistor R2, a discharge resistor R3 and a test capacitor C2. The nanosecond-level rising edge high voltage pulse generation device is simple in structure, convenient to operate and good in stability; besides, rising edges are fast, and frequency and the duty ratio can be modulated. In the fields of laser ionization spectroscopy, laser mass-spectrometric technique and the like, a pulse field of nanosecond-level rising edges can be provided for a rydberg state field ionization process, and therefore a high ionization rate can be realized in the rydberg state field ionization process.

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...
