Ideal Spectroscopy SpectraJet Pulsed Discharge Jet Nozzle and PDD-100 Pulsed Discharge Driver Kit for LIF and Molecular Beam Spectroscopy This Ideal Spectroscopy SpectraJet Pulsed Discharge Jet Kit combines the SpectraJet Single Pulsed Discharge Jet Nozzle with the PDD-100 Pulsed Discharge Driver to provide an integrated solution 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 selected chemical precursor can be entrained in a high-pressure inert buffer gas such as argon or helium. The pulsed valve delivers a controlled gas pulse through the discharge region, where the PDD-100 provides a precisely timed electrical discharge to fragment or dissociate the precursor immediately before expansion into the vacuum chamber. The resulting supersonic expansion rapidly cools the generated molecular species while minimizing downstream collisions and secondary reactions. This produces a pulsed molecular beam suitable for Laser-Induced Fluorescence (LIF), Dispersed Fluorescence (DF), emission spectroscopy, high-resolution molecular spectroscopy, and other gas-phase molecular beam experiments. The included PDD-100 Pulsed Discharge Driver operates from an 18 to 36 VDC power source and accepts a TTL-compatible trigger input, allowing the electrical discharge to be precisely synchronized with the SpectraJet pulsed valve, laser, detector, and laboratory timing system. The driver provides an SHV high-voltage output for connection to the discharge electrode assembly through an appropriate vacuum feedthrough. By combining the SpectraJet nozzle and PDD-100 driver into one kit, researchers have the primary discharge-generation components required for a coordinated pulsed discharge jet source without having to separately select and match the discharge nozzle and driver.

Ideal Spectroscopy TwinJet Dual Pulsed Discharge Jet Nozzle and Two PDD-100 Pulsed Discharge Driver Kit for LIF and Molecular Beam Spectroscopy This Ideal Spectroscopy TwinJet Dual Pulsed Discharge Jet Kit combines the TwinJet Dual Pulsed Discharge Jet Nozzle with two PDD-100 Pulsed Discharge Drivers to provide an integrated solution for generating radicals, transient molecules, and reactive intermediates from two independently controlled precursor streams. The TwinJet is an advanced two-precursor molecular beam source designed for experiments requiring reactive molecular species that may be difficult or impossible to generate using a conventional single-stream discharge nozzle. The system incorporates two independent high-speed pulsed valves, two separate precursor and buffer-gas channels, and two independently energized discharge sections that converge at a common mixing region near the throat of the supersonic expansion nozzle. Each TwinJet channel can carry a different chemical precursor diluted in a high-pressure inert buffer gas such as argon or helium. The two precursor mixtures remain physically separated within their respective valves and discharge passages, helping prevent premature reactions while allowing unstable, incompatible, or highly reactive precursor combinations to be introduced as independent streams. Two included PDD-100 Pulsed Discharge Drivers independently control the TwinJet discharge sections. Each driver accepts a TTL-compatible trigger input, allowing the two electrical discharges to be precisely synchronized with the pulsed valves, excitation laser, detector, and laboratory timing or data-acquisition system. Each PDD-100 operates from an 18 to 36 VDC power source and provides an SHV high-voltage output for connection to the corresponding discharge electrode assembly. The independent configuration allows researchers to discharge both precursor streams, discharge only one stream, or introduce either stream without discharge depending on the reaction pathway being investigated. Valve timing, discharge timing, precursor concentration, buffer gas selection, backing pressure, and discharge conditions can be independently optimized for each side. After passing through their respective discharge regions, the two gas streams enter a short mixing region near the nozzle throat. Reactive fragments generated in the separate channels are combined immediately before expansion into the vacuum chamber. This arrangement helps minimize premature reactions, precursor decomposition, wall reactions, and unwanted secondary chemistry. The resulting supersonic expansion rapidly cools the reaction products, producing a pulsed molecular beam containing rotationally cold radicals and reactive intermediates. The TwinJet system is well suited for Laser-Induced Fluorescence (LIF), Dispersed Fluorescence (DF), emission spectroscopy, high-resolution molecular spectroscopy, and other gas-phase experiments requiring controlled generation of short-lived molecular species.

Ideal Spectroscopy Photodiode Variable Bias Module, 0-24 VDC 24V, 2A DC Converter Power Supply Included This is an 0-24 VDC Ideal Spectroscopy photodiode variable bias module with included 24V, 2A DC power supply. This module is used to apply a DC bias to a compatible photodiode for greater sensitivity and linearity, and more rapid time response. The bias voltage is adjusted via a rotatable knob on the side of the bias module. The photodiode must be attached via the input female BNC connector. The output is monitored by connection to the output female BNC connector. Optionally, the 0-24 VDC bias voltage may be monitored via connection to the bias monitor female BNC connector for precise voltage control. Photodiodes are light detectors used in many spectroscopy applications. An unbiased photodiode acts as a photovoltaic device, which generates a single electron of current per excitation event. The photodiode output may be monitored either by measuring the current produced or by applying a resistance to the photodiode output and measuring the voltage build up as current is impeded. Photovoltaic operation is the simplest mode of action and has minimal dark current. Unfortunately it suffers from low amplification, nonlinear voltage response over large dynamic ranges, and slow response due to a short depetion width and large junction capacitance. Unbiased photodiodes are best for slow or very low light applications. Photodiodes may be reverse biased to change their response from photovoltaic to photoconductive. Under reverse biasing the depletion width increases, the junction capacitance decreases, and the response speeds up. The current response is amplified and becomes more linear over a larger dynamic range than in photovoltaic mode. The cost of these enhancements is increased dark noise and the propagation of electrical artifacts from the biasing power supply to the photodiode output signal. Using a clean power supply, such as Ideal Spectroscopy’s photodiode bias module, is critical for good response. Biasing photodiodes is best for applications where rapid time response or high linearity over a large range of light intensities is needed.
