How to fire projectiles through materials without breaking anything

It sounds a bit like a magic trick

29-Nov-2022 - When charged particles are being shot through ultra-thin layers of material, sometimes spectacular micro-explosions occur, sometimes the material remains almost intact. This has now been explained at the TU Wien. It sounds a bit like a magic trick: Some materials can be shot through with fast, ...
