摘　　要：Resorcinol/formaldehyde(RF)foam resin is an attractive material as a low-density target in high-power laser–plasma experiments because of its fine network structure,transparency in the visible region,and low-Z element(hydrogen,carbon,and oxygen)composition.In this study,we developed disk-shaped RF foam and deuterated RF foam targets with 40–200μm thickness and approximately 100 mg/cm^(3) density having a network structure from 100 nm to a few micrometers cell size.By deuteration,the polymerization rate was drastically slowed down owing to kinetic isotope effects.These targets were used in high-power laser experiments where a megaelectronvolt proton beam was successfully generated.
