A microcalorimeter spectrometer for the investigation of laboratory plasmas
2002
We describe a cryostat and 2-stage ADR specifically designed for making measurements at the NIST EBIT (Electron Beam Ion Trap) facility. The design is compact and consists of a single helium bath with two vapor-cooled shields. The 2-stage ADR has two separate magnets and two heat switches. The interface between the EBIT and microcalorimeter array will also be described.
Petrological and noble gas features of Lascar and Lastarria volcanoes (Chile): Inferences on plumbing systems and mantle characteristics
2020
Lascar (5592 m a.s.l.) and Lastarria (5697 m a.s.l.) are Chilean active stratovolcanoes located in the Central Volcanic Zone (CVZ; 16°S to 28°S) that have developed on top of a 71 km thick continental crust. Independently of the similarities in their Plinian/Vulcanian eruptive styles, their complex magmatic feeding structures and the origins of their magmatic fluids still necessitate constraints in order to improve the reliability of geochemical monitoring. Here we investigate the petrography, bulk-rock chemistry, and mineral chemistry in products from the 1986–1993 explosive eruptive cycle at Lascar and from several Holocene eruptive sequences at Lastarria. These data are integrated with m…
