Compact acceleration of energetic neutral atoms using high intensity laser-solid interaction

Abstract Recent advances in high-intensity laser-produced plasmas have demonstrated their potential as compact charge particle accelerators. Unlike conventional accelerators, transient quasi-static charge separation acceleration fields in laser produced plasmas are highly localized and orders of mag...
