Magnets for cyclotrons [PDF]

, 2006
Different design aspects of cyclotrons and magnets for cyclotrons are reviewed. The cyclotron magnet design should be considered as an iterative process starting from a simple model that requires the vision of the complete cyclotron and the possibility ...

A Deterministic Model of the Gamma Radiation at the Soil Surface–Including Soil Moisture Correction for Better Radiation Data Exploitation in Soil Mapping

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 2, Page 299-311, April 2025.
ABSTRACT Background During the last decades, gamma spectrometry data have increasingly been used in soil science, for example, for mapping. However, the full data potential could not be exploited due to certain constraints, among which the insufficient representation of attenuating materials (in particular, water) in correction algorithms is the most ...

Stonehenge revisited: A geochemical approach to interpreting the geographical source of sarsen stone #58

Archaeometry, Volume 67, Issue 1, Page 1-19, February 2025.
Abstract It is tempting in material sourcing analyses to treat chemical data primarily as numbers to be sorted, while disregarding their interlinked geochemistries. Consideration of geochemistry, however, often leads to the drawing of more nuanced and reliable conclusions.

Calculating Sedimentation Rates of Oxic Pelagic Clays Using Core Top Thorium Isotopes

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 1, January 2025.
Abstract Oxic pelagic clays are an important component of seafloor sediment that may hold valuable information about past ocean chemistry due to their affinity for and accumulation of biogeochemically important metals. We present a new approach to calculating site‐specific sedimentation rates (SRs) by comparing authigenic sediment thorium isotope ...

Investigation of Conventional Radiation and Radionuclide at Ba‐Phalaborwa Roads, South Africa

Applied and Environmental Soil Science, Volume 2025, Issue 1, 2025.
Road surface screening with the AT6101CE GPS detector was conducted in the Ba‐Phalaborwa area of South Africa to provide a thorough distribution map of radioactive pollution and absorbed dose rate contribution. The AT6101CE GPS detector detected radionuclides, including 226Ra, 232Th, 40K, 51Cr, and 99Mo.

Magma Ocean Evolution at Arbitrary Redox State

Journal of Geophysical Research: Planets, Volume 129, Issue 12, December 2024.
Abstract Interactions between magma oceans and overlying atmospheres on young rocky planets leads to an evolving feedback of outgassing, greenhouse forcing, and mantle melt fraction. Previous studies have predominantly focused on the solidification of oxidized Earth‐similar planets, but the diversity in mean density and irradiation observed in the low ...
