SUREAL-23 D2.1 Super-Continuum Laser Multiwavelength Photoacoustic Aerosol Spectrometer (SCL-MPAS)

This report aims to document the delivered demonstrator “D2.1 Super-continuum laser multi-wavelength photoacoustic spectrometer setup”, a prototype instrument developed in the frame of WP2 “Technology development”, Task 2.1 “Multi-wavelength photoacoustic technology for composition analysis” of the SUREAL-23 project. It describes the principle of operation of the chosen concept, the main SCL-MPAS system components developed/selected as well as an initial conceptual/physical system layout. This prototype will continue to undergo improvements and will be available for sub-23 nm combustion aerosol characterisation in the SUREAL-23 project.
