Abstract (Description of Research)
This work presents the desig and development of an alkali metal oven used for charge-transfer collision experiments within the Beamline for Ionic and Neutral Collisions (BLINC) at Southern Adventist University. This oven is engineered to produce a stable and controllable alkali vapor source (K/Cs), enabling interactions between the H2+ ions and neutral alkali atoms for the study of rovibrational energy transfer.
The alkali metal oven was designed to be modular to switch out different capillary designs for diverse vapor release into the beamline. This system was designed using SolidWorks and fabricated through CNC machining, with particular emphasis on thermal wiring for heating of the oven to release the alkali metals as gas through the capillaries. The key feature of this design is the modular capillary system that allows for interchangeable nozzle/capillary geometries to investigate the effects of capillary dimensions on vapor density, velocity distributions, and angular divergence.
This oven is designed to integrate with future laser-induced fluorescence (LIF) diagnostics, enabling quantitative characterization of vapor properties using optical methods. This work provides a critical component for controlled alkali vapor delivery in beamline applications and establishes a flexible platform for future experimental optimization and collision cross-section measurements.
