AB  - This work investigates the performance of the electrospray aerosol generator atthe European X-ray Free Electron Laser (EuXFEL). This generator is, togetherwith an aerodynamic lens stack that transports the particles into the X-rayinteraction vacuum chamber, the method of choice to deliver particles for single-particle coherent diffractive imaging (SPI) experiments at the EuXFEL. Forthese experiments to be successful, it is necessary to achieve high transmission ofparticles from solution into the vacuum interaction region. Particle transmissionis highly dependent on efficient neutralization of the charged aerosol generatedby the electrospray mechanism as well as the geometry in the vicinity of theTaylor cone. We report absolute particle transmission values for differentneutralizers and geometries while keeping the conditions suitable for SPIexperiments. Our findings reveal that a vacuum ultraviolet ionizer demonstratesa transmission efficiency approximately seven times greater than the soft X-rayionizer used previously. Combined with an optimized orifice size on the counterelectrode, we achieve > 40
