Implantation and re-emission of hydrogen and helium in the beam-stopping panels of a 10 MW ion beam line

Significant amounts of hydrogen and helium are found to be implanted into the beam-stopping panels during beam operation. The amount implanted appears to exceed the particle flux of the beam in the early stages of the pulse. Gas is released during the pulse, probably due to the warming up of the bea...

Summary:Significant amounts of hydrogen and helium are found to be implanted into the beam-stopping panels during beam operation. The amount implanted appears to exceed the particle flux of the beam in the early stages of the pulse. Gas is released during the pulse, probably due to the warming up of the beam-stopping panels. The gas concentration in the beam-stopping panels is ~ 10 22 cm −3. The concentration and release of hydrogen and helium are comparable, indicating a common process.
