Description
Numerous avenues of development are being pursued to expand the capabilities of the Resonance Ionization Laser Ion Source (RILIS) beyond the CERN Long Shutdown 2. To improve the reach of the solid-state laser system and offer greater flexibility during ionization scheme development, promising progress in the extending of the spectral range of the existing titanium-sapphire lasers through stimulated Raman scattering has been made [1]. Results of a prototype cavity that allows for efficient generation of broadband light in the blue-green region, without relying upon UV-pumped dye lasers, will be presented. A new beam observation system has been designed so that laser beams can be positionally stabilized within both the HRS and GPS ion sources simultaneously. This will reduce a common bottleneck during on-line setups and in some cases even permit dual-separator operation. An exploratory study investigating the feasibility of fragmenting simple molecules using ultrashort laser pulses in realistic ion source conditions has been performed. The MELISSA laser laboratory was commissioned earlier in the year and has been in operation for the MEDICIS scientific program of 2019. A brief overview of this new laser ion source will be provided.
