Abstract

High efficiency of negative ion beam neutralization by using a photon target is presented in this work. The target was designed and manufactured on principles of nonresonance adiabatic confinement of photons. This photon trap shaped a long arc blended with end spherical mirrors. The arc part consists several cylinder mirrors. Trap sizes was about 30×50×250 mm3. A photon flux from an industrial fiber laser (λ =1070 nm, Δλ=7nm, P=2.1 kW) was injected into trap normally to one cylinder mirror through small entrance hole with angular spread about 3 degree. Test negative ion beams were passed through photon confinement region and suppressing ion current was registered. These experiments has been carried out with H-, D- beams. High neutralization degree more than 95% has been demonstrated.
