Can Ablation of Materials Neutralize In-Flight Atomic Beams?

[Malamala]

Hello! Someone mentioned to me about about a way to produce in flight neutralization of atomic/molecular beams by making the beam pass through a gas of particles produce through ablation (and not use a neutralization cell as it is often done). From my understanding, basically, one has a region where they ablate some material, and the beam of interest passes through the plasma created during the ablation and it gets neutralized. They mentioned it was a group from Japan (not totally sure), but I couldn't find that online. Does anyone know anything about this and point me towards a paper? Thank you!

What material is being ablated? Something like Cs? Bi?

Thanks for this, I will take a look. I am actually not sure about the material in the paper I was told about.
