Technical note: Two-component electrical-conductivity-based hydrograph separation employing an exponential mixing model (EXPECT) provides reliable high-temporal-resolution young water fraction estimates in three small Swiss catchments

Jana Freiin von Freyberg, Davide Canone

The young water fraction represents the portion of water molecules in a stream that have entered the catchment relatively recently, typically within 2-3 months. It can be reliably estimated in spatially heterogeneous and nonstationary catchments from the a ...

The isotopic signature of U(V) during bacterial reduction

Marinella Mazzanti, Rizlan Bernier-Latmani, Margaux Camille Andréa Molinas, Radmila Faizova, Ashley Richards Brown

The two-step electron transfer during bacterial reduction of UVI to UIV is typically accompanied by mass-independent fractionation of the 238U and 235U isotopes, whereby the heavy isotope accumulates in the reduced product. However, the role of the UV inte ...

The role of isotope mass and transport for H-mode access in tritium containing plasmas at JET with ITER-like wall

Haomin Sun, Henri Weisen, Javier García Hernández, Marco Wischmeier, Nicola Vianello, Mikhail Maslov

The required heating power, P-LH, to access the high confinement regime (H-mode) in tritium containing plasmas is investigated in JET with ITER-like wall at a toroidal magnetic field of B-t = 1.8 T and a plasma current of I-p = 1.7 MA. PLH, also referred t ...

Characterizing airborne snow metamorphism using stable water isotope measurements in snow and vapor from ring wind tunnel experiments

Michael Lehning, Sonja Wahl, Luca Bianchi, Benjamin Andreas Walter

Drifting-blowing snow events are frequent phenomena in alpine and polar regions with direct effects on the local mass and energy balance that are difficult to quantify. In addition to this immediate impact of the blowing snow cloud the aeolian transport mo ...

High-useful yield and new autoionizing state of resonantly ionized tungsten

Reto Georg Trappitsch

In order to measure tungsten isotopic composition in presolar stardust grains that contain a limited number of atoms, we developed a new three-photon three-color resonance ionization scheme using titanium:sapphire lasers and the Laser Ionization of Neutral ...

Design of the 590 MeV proton beamline for the proposed TATTOOS isotope production target at PSI

Mike Seidel, Hong Zhang

IMPACT (Isotope and Muon Production with Advanced Cyclotron and Target Technologies) is a proposed initiative envisaged for the high-intensity proton accelerator facility (HIPA) at the Paul Scherrer Institute (PSI). As part of IMPACT, a radioisotope target ...

Four years of daily stable water isotope data in stream water and precipitation from three Swiss catchments

Jana Freiin von Freyberg

This dataset contains four years of daily measurements of the natural isotopic composition (2H, 18O) of precipitation and stream water at the Alp catchment (area 47 km2) in Central Switzerland and two of its tributaries (0.7 km2 and 1.6 km2). In addition, ...

The inFuence of drifting and blowing snow on surface (turbulent) mass- and energy exchange assessed with different methods

Michael Lehning, Wolf Hendrik Huwald, Jérôme François Sylvain Dujardin, Franziska Gerber, Daniela Brito Melo, Armin Sigmund, Benjamin Andreas Walter

Drifting and blowing snow is a dominant process shaping snow-covered surfaces in particular in extreme environments such as high mountains or polar regions. Because the process is complicated to describe, as it covers scales from below 1 mm to several kilo ...
