Time-Dependent Searches For Point Sources Of Neutrinos With The 40-String And 22-String Configurations Of Icecube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

This paper presents four searches for flaring sources of neutrinos using the IceCube neutrino telescope. For the first time, a search is performed over the entire parameter space of energy, direction, and time with sensitivity to neutrino flares lasting be ...

Displacement damage effects in silicon MEMS at high proton doses

Herbert Shea, Joao Gomes Pereira Junior

We report on a study of the sensitivity of silicon MEMS to proton radiation and mitigation strategies. MEMS systems can degrade due to ionizing radiation (electron-hole pair creation) and non-ionizing radiation (displacement damage), such as electrons, tra ...

Practical solutions for reliable triple probe measurements in magnetized plasmas

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Philippe Marmillod

The triple probe method to obtain local, time-resolved measurements of density, electron temperature and plasma potential is investigated in detail. The difficulties in obtaining reliable measurements with this technique are discussed and overcome. These i ...

On the 3D Reconstruction of Coronal Mass Ejections using Coronagraph Data

Coronal Mass ejections (CMEs) are enormous eruptions of magnetized plasma expelled from the Sun into the interplanetary space, over the course of hours to days. They can create major disturbances in the interplanetary medium and trigger severe magnetic sto ...

Comparing magnetic triggering of ELMs in TCV and ASDEX Upgrade

Yves Martin, Laurent Villard, Jonathan Bryan Lister, Sun Hee Kim

Frequency locking of edge localized modes (ELMs) to the vertical plasma movements induced by magnetic perturbations first demonstrated in TCV was successfully repeated in ASDEX Upgrade. However, the ELMs were triggered in ASDEX Upgrade when the plasma was ...

Mid- to late Holocene climate change- an overview

Jed Oliver Kaplan, Stefan Müller

The last 6000 years are of particular interest to the understanding of the Earth System because the boundary conditions of the climate system did not change dramatically (in comparison to larger glacial–interglacial changes), and because abundant, detailed ...

On the Relationship Between the Signature of Close Electric Field and the Equivalent Corona Current in Lightning Return Stroke Models

Carlo Alberto Nucci

Engineering return stroke models can be categorized either as current generation (traveling current source type) models or current propagation (transmission line type) models. The current generation models are described among other parameters by a corona c ...

Study of the solar anisotropy of cosmic ray primaries of about 200 GeV energy with the L3+C muon detector

Qian Wang, Aurelio Bay, Horst Vogel, Eduardo Sanchez, Zhirui Xu, Werner Lustermann, Liang Sun, Jian Zhao, Yu Lei, Ji Hyun Kim, Zheng Wang, Matthias Weber, Xiao Wang, Yifei Guo, Xuan Yang

Context. Primary cosmic rays experience multiple deflections in the non-uniform galactic and heliospheric magnetic fields which may generate anisotropies. Aims. A study of anisotropies in the energy range between 100 and 500 GeV is performed. This energy r ...

Turbulence in cooling channels of rocket engines: Large Eddy Simulations

The aim of this Note is to predict by means of large eddy simulations the three-dimensional structures and secondary mass and heat fluxes which develop within a heated curved duct, for applications to rocket engines cooling channels. We show the existence ...

Plasma production by low-field side injection of electron cyclotron waves in a simple magnetized torus

Ambrogio Fasoli, Benoît Labit, Mario Ludovico Podesta, Francesca Maria Poli

The mechanisms leading to ionization of neutral gas by means of microwaves in the electron cyclotron range of frequencies in a simple toroidal plasma configuration are investigated in the TORPEX device (Fasoli A et al 2003 Bull. Am. Phys. Soc. 48 119). The ...
