(2022). Fabrication of disk-shaped, deuterated resorcinol/formaldehyde foam target for laser–plasma experiments. High Power Laser Science and Engineering. 9. e31.2095-4719https://mro.massey.ac.nz/handle/10179/70704Resorcinol/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 40–200 µm thickness and approximately 100 mg/cm3 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.(c) 2021 The Author/sCC BY 4.0https://creativecommons.org/licenses/by/4.0/deuterated materiallow-density materialresorcinolformaldehyde foamJournal article10.1017/hpl.2021.152052-3289journal-articlehttp://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000663741200001&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=c5bb3b2499afac691c2e3c1a83ef6fefARTN e31
