The duoplasmatron as a vacuum ultraviolet light source
Description of duoplasmatron and its use for production of ultraviolet light
Electron beams from duoplasmatron using hollow cathode arc, noting current density distributions
We present results from online optimization studies of a duoplasmatron ion source designed to produce 50~keV protons for acceleration to 2.5~MeV and subsequent injection into the Integrable Optics Test Accelerator (IOTA) at Fermilab. Using a Bayesian exploration technique, we developed multi-parameter models of the source s proton current and employed these models to optimize its performance. Depending on the spectrometer configuration used to isolate the proton beam and the chosen optimization objective, we identified three candidate operating points, achieving normalized 50~\% emittances between 0.57 and 1.3~\textmu m and a maximum proton current of $14.5 \pm 0.6$~mA.
A series of numerical start-to-end simulations of Phase 1 of the 750 keV RFQ Test Stand which includes the ion source (H+ duoplasmatron), a 1-Solenoid LEBT, an emittance scan station and a Faraday cup were performed to find a mechanism for the characterization of the proton beam extracted from the duoplasmatron.
