biostudies-literatureUnknown9(24)Andrew Musgrave CSHere, we show the easy-handling of a liquid gallium-tin alloy (Ga : Sn) as a laser target source for 13.5 nm light generation. The alloys have ∼30 °C freezing points according to a differential scanning calorimetry cooling process. A Nd:YAG laser (1064 nm, 1 ns, 7.1 × 10¹⁰ W cm^-2) ablated the alloys, obtaining a similar extreme ultraviolet emission intensity to Sn despite a small quantity of Sn. Finally, we demonstrate a liquid metal alloy jet and droplets using a plastic nozzle for high-repetition target supply.RSC advances13927-13932https://www.ebi.ac.uk/biostudies/studies/S-EPMC9064005biostudies-literatureGallium-tin alloys as a low melting point liquid metal for repetition-pulse-laser-induced high energy density state toward compact pulse EUV sources.PMC9064005Nagai KAndrew Musgrave CSLu NSato RfalseGallium-tin alloys as a low melting point liquid metal for repetition-pulse-laser-induced high energy density state toward compact pulse EUV sources.Here, we show the easy-handling of a liquid gallium-tin alloy (Ga : Sn) as a laser target source for 13.5 nm light generation.
