Description
High energy ion acceleration beyond 10 MeV is driven by high intensity lasers in the Target Normal Sheath Acceleration (TNSA) regime.
However, contaminants on a solid target surface degrade the performance of heavy ion acceleration.
We proposed the tape target with heating to supply contamination-free targets with long term operation.
In this presentation, laser-driven ion acceleration using a 5 µm Ti with CW laser heating was demonstrated for oxygen ion source.
A Thomson parabola spectrometer provided evidence that oxygen ions were preferentially accelerated compared to the case without the heating.
The results indicate stable thin oxide layers on the surface of the Titanium foil can be accelerated when we apply the heating.
