A single layer graphene has thickness of 1 nm, which is the thinest target in the world. In order to investigate effects of target thickness in nm scales, we prepare single, double, four and eight layer graphene targets. We utilize a double-plasma mirror to suppress the pre pulse. The accelerated ions are detected with a stack of radiochromic films (RCFs) and CR-39. From the RCF stacks, with double and four layer graphene we obtained energetic ions with at least 70 MeV per nuclei. We distinguish the ion species and estimate ion energy with CR-39., Plasma Conference 2017}, title = {Energetic ion acceleration with a suspended graphene}, year = {2017} }
