The Ideal Spectroscopy SpectraJet™ Single Pulsed Discharge Jet Nozzle is a research-proven source for generating radicals, transient molecules, and reactive intermediates in rotationally cold supersonic molecular beams. The SpectraJet integrates a high-speed pulsed valve, electrical discharge section, and supersonic expansion nozzle into a compact assembly designed for installation inside a vacuum chamber.
During operation, a small concentration of a selected chemical precursor is entrained in a high-pressure inert buffer gas such as argon or helium. The integrated pulsed valve delivers a short, controlled gas pulse through the discharge section, where a precisely timed electrical discharge fragments or dissociates the precursor immediately before the gas expands into the vacuum chamber.
The rapid free-jet expansion cools the newly formed molecular species to low rotational temperatures while minimizing collisions and secondary reactions downstream of the nozzle. The resulting pulsed molecular beam is ideal for Laser-Induced Fluorescence (LIF), Dispersed Fluorescence (DF), emission spectroscopy, and other gas-phase molecular spectroscopy techniques.
The SpectraJet is an excellent choice for experiments where the desired species can be produced from a single precursor or from a premixed precursor and buffer-gas formulation. Discharge timing, valve timing, precursor concentration, buffer gas selection, and backing pressure can all be optimized for the specific molecule under investigation.
The discharge section is powered by one Ideal Spectroscopy PDD-100 Pulsed Discharge Driver. Its TTL-compatible triggering allows the electrical discharge to be precisely synchronized with the pulsed valve, laser, detector, and laboratory timing system. High-voltage output is supplied to the nozzle electrode assembly through an SHV cable and an appropriate vacuum feedthrough.
The SpectraJet provides laboratories with a practical, repeatable alternative to assembling a pulsed discharge source from individual valves, electrodes, insulating components, nozzles, and high-voltage connections. It is designed for researchers who want to move efficiently from vacuum chamber installation to reactive-species generation and spectroscopic data collection.
Custom Materials Science and Surface Processing Applications
Beyond molecular spectroscopy, the SpectraJet™ and TwinJet™ platforms can be adapted for experimental materials science applications requiring timed delivery, activation, mixing, or directed expansion of gaseous precursors and reactive species into a vacuum chamber. Potential research applications include pulsed and reactive molecular beam experiments, gas-surface reaction studies, precursor screening, radical-assisted surface processing, thin-film and coating development, nanoparticle or cluster formation, and specialized gas-source, hybrid, or plasma-assisted epitaxy research.
The independently controlled TwinJet™ configuration is especially valuable when two precursors must remain isolated until activation or mixing near the nozzle exit. Because deposition systems vary widely in operating pressure, gas load, substrate geometry, operating temperature, material compatibility, beam distance, and process-control requirements, these products should be evaluated and configured for each specific application.
Ideal Vacuum welcomes custom source, nozzle, electrode, valve, mounting, feedthrough, heating, cooling, and control-system design requests for new vacuum processing and advanced materials research applications.
