Extreme value theory applied to the millennial sunspot number series [PDF]

open access: yes, 2018
In this work, we use two decadal sunspot number series reconstructed from cosmogenic radionuclide data (14C in tree trunks, SN-14C and 10Be in polar ice, SN-10Be) and the Extreme Value Theory to study variability of solar activity during the last 9 ...

Tracer Applications of Noble Gas Radionuclides in the Geosciences

open access: yes, 2013
The noble gas radionuclides, including 81Kr (half-life = 229,000 yr), 85Kr (11 yr), and 39Ar (269 yr), possess nearly ideal chemical and physical properties for studies of earth and environmental processes.

Measurement of 139La(p,x) cross sections from 35–60 MeV by stacked-target activation [PDF]

open access: yes, 2019
A stacked-target of natural lanthanum foils (99.9119% 139La) was irradiated using a 60 MeV proton beam at the LBNL 88-Inch Cyclotron. 139La(p,x) cross sections are reported between 35–60 MeV for nine product radionuclides. The primary motivation for this

Cosmogenesis Backgrounds, Experiment Depth and the Solar Neutrino TPC

open access: yes, 2002
A Time Projection Chamber (TPC) is one of the promising candidates to perform unique measurements in solar neutrino physics. Its features will enable it to work at depths of the order of 2000 mwe.

Closed Fuel Cycle and Minor Actinide Multirecycling in a Gas-Cooled Fast Reactor

open access: yesScience and Technology of Nuclear Installations, 2009
The Generation IV International Forum has identified the Gas-Cooled Fast Reactor (GCFR) as one of the reactor concepts for future deployment. The GCFR targets sustainability, which is achieved by the use of a closed nuclear fuel cycle where only fission ...
