Spectral, spatial and temporal characteristics of a millisecond pulsed glow discharge: metastable argon atom production
Time resolved atomic emission, atomic absorbance, and laser-induced atomic fluorescence measurements of a Ž3 . millisecond pulsed glow discharge, made perpendicular to the insertion probe, provide temporal profiles of 1s P 5 2 Ž3 . and 1s P metastable argon atom populations. Acquisition of these profiles at different spatial positions in the 3 0 plasma provides data from which two-dimensional s...
متن کاملBulk plasma properties in the pulsed glow discharge
This work focuses on the spatial and temporal characteristics of a glow discharge plasma operated with power pulses of 5 ms in duration at 25% duty cycle. Interpretation of emission data provides insight into the nature of the plasma at each instant of a typical pulse cycle and at each position in space. Because the bulk plasma properties affect the distribution of excited energy levels of the ...
متن کاملParticle beam glow discharge mass spectrometry: spectral characteristics of nucleobases.
Use of a particle beam glow discharge (PB-GD) source for mass spectrometric determinations of deoxy- and ribonucleosides and nucleotides is described. Use of this combination of sample introduction and ion source decouples the vaporization and ionization steps, leading to very simple spectral structure. The mass spectra of these compounds are EI-like in nature, with clearly identified molecular...
متن کاملDust acoustic waves in a direct current glow discharge
An experimental investigation of dust acoustic ~DA! waves in a dc glow discharge plasma is described. The glow discharge is formed between a 3 cm anode disk and the grounded walls of a 60 cm diameter vacuum chamber which is filled with nitrogen gas at a pressure of about 100 mTorr. Dust located on a tray in the chamber is attracted into the plasma where it is trapped electrostatically. The dust...
متن کاملModeling of a millisecond pulsed glow discharge: Investigation of the afterpeak
We have developed a comprehensive modeling network for a millisecond pulsed glow discharge in argon (Ar) with copper (Cu) cathode, to describe the behavior of the various plasma species. Typical results of the model are shown, such as the potential distribution during and after the pulse, the densities of Ar ions, Ar atoms in the metastable and various other excited levels, Cu atoms and Cu ions...
