Earthward Propagated Auroral Kilometric Radiation: Observations From Polar
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Auroral Kilometric Radiation (AKR), the strongest natural radio emission from Earth's magnetosphere, has been primarily observed in space. It is generally understood to propagate anti‐Earthward and be detected at large radial distances, while Earthward‐directed waves are thought to be blocked by the ionosphere. Surprisingly, AKR‐like emissions

BEAM DIAGNOSTICS FOR CYCLOTRONS
, 2010 An overview of beam diagnostic systems for cyclotron operation and development is presented. The focus is on devices installed within the cyclotron with its special "environmental" conditions and limitations.

ChemPhysChem, Volume 27, Issue 12, 26 June 2026.HO•‐induced oxidation is structurally resolved in S‐adenosyl methionine (SAM). Infrared multiple photon dissociation (IRMPD) spectroscopy and density functional theory (DFT) calculations reveal clear spectroscopic signatures of adenine C8 oxidation. S‐adenosyl methionine (SAM) is a key biomolecule in cellular processes, acting as a primary methyl donor,

Cost-effective Design Options for IsoDAR
, 2012 This whitepaper reviews design options for the IsoDAR electron antineutrino source. IsoDAR is designed to produce $2.6 \times 10^{22}$ electron antineutrinos per year with an average energy of 6.4 MeV, using isotope decay-at-rest.

New magnet pole shape for isochronous cyclotrons [PDF]
, 1981 A new design has been developed for shaping pole tips to produce the radially increasing fields required for isochronous cyclotrons. The conventional solid hill poles are replaced by poles mounted over a small secondary gap which tapers radially from ...

First Observation of the Second Harmonic of Upper Band Chorus Waves Linking to Slow Z‐Mode
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The Z‐mode, comprising fast and slow branches, is a ubiquitous electromagnetic wave in planetary magnetospheres. While fast Z‐mode generation is attributed to electron cyclotron maser instability, the slow Z‐mode mechanism remains unresolved.

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Supra‐permafrost groundwater (SPGW) is a significant but understudied source of dissolved organic matter (DOM) to Arctic coastal systems. We applied ramped pyrolysis/oxidation (RPO) with Δ14C and δ13C isotopic analysis to assess DOM reactivity and origin in SPGW, river, and lagoon waters along the Alaska Beaufort Sea coast.

REVIEW OF CYCLOTRONS USED IN THE PRODUCTION OF RADIO-RADIOISOTOPES FOR BIOMEDICAL APPLICATIONS
, 2010 Cyclotrons are the primary tool for producing the shorter-lived proton-rich radio-isotopes currently used in the biosciences. Although the primary use of the cyclotron produced short-lived radio-isotopes is in PET/CT and SPECT diagnostic medical ...

Plasma Stability in Turbulent Magnetic Flux Ropes Downstream of a Collisionless Shock
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract How pre‐existing solar wind turbulence, and coherent structures such as magnetic flux ropes within it, influence the transition of plasma across a shock is still poorly understood. Recently, in situ observations from the Earth's magnetosheath have been used to study plasma stability against ion kinetic instabilities. In the turbulent flow, the
