A double pulse method for glow discharge enhancement

Electrical properties of the µs pulsed glow discharge in a Grimm-type source: comparison of dc and rf modes

“…The high current peak at the beginning of the pulse has already been observed by others. 20,35,44 Because of the strong excitation and ionization conditions, the region at the beginning of the pulse is often used in time-gated measurements to extract elemental information from the sample. 14 However, the origin of the high current after the plasma ignition is still not clear.…”

New μs-pulsed DC glow discharge assembly on a fast flow high power source for time resolved analysis in high resolution mass spectrometry

“…This code is then compiled using software tools provided by Xilinx and then downloaded to the FPGA. It requires only a small change of code to produce a double pulse 13 or even a triple pulse. This ms-PGD assembly allows control of the pulse voltage from 0 to À2 kV, the frequency up to 10 kHz, the pulse width from 1 ms to 65 ms and the pulse-off time from 0 to 65 ms.…”

Advances in atomic emission, absorption and fluorescence spectrometry and related techniques

“…Pulsed glow discharges have received some attention. [207][208][209][210][211] A double pulse method has been used to enhance atomic emission in a Ne GD, whereby the second pule is applied at a variable delay after the first pulse. 208 A microsecond pulsed Ar GD has been modelled to predict the densities of Ar metastables, and sputtered Cu atoms and ions, both spatially and temporally.…”
