Detailed calibrations of the Madison Symmetric Torus polychromator Thomson scattering system have been made suitable for electron temperature fluctuation measurements. All calibrations have taken place focusing on accuracy, ease of use and repeatability, and in situ measurements wherever possible. Novel calibration processes have been made possible with an insertable integrating sphere (ISIS), ...

Electron cloud formation and the associated effects of beam loss and instabilities have been observed in high intensity proton machines such as the LANL PSR and the CERN SPS. A program has recently been launched at the Rutherford Appleton Laboratory (UK) to understand the lack of electron cloud induced instabilities in the operations of the 160 kW 70-800 MeV ISIS synchrotron. Simulations have b...

Oytun Orhan has been working as a researcher at ORSAM since 2009. Conducting research basically on Syria and Lebanon, Orhan has also carried out studies about Israeli-Palestinian conflict, Iraq and Turkey’s Middle East policy. Having graduated from the department of International Relations, Gazi University, Orhan completed his master’s degree at the department of International Relations, Hacett...

This document describes an optional mechanism within Intermediate System to Intermediate Systems (IS-ISs) used today by many ISPs for IGP routing within their clouds. This document describes how to run, within a single IS-IS domain, a set of independent IP topologies that we call Multi-Topologies (MTs). This MT extension can be used for a variety of purposes, such as an in-band management netwo...

The neutrino experiment KARMEN is situated at the beam stop neutrino source ISIS. It provides νμ’s, νe’s and ν̄μ’s in equal intensities from the π–μ–decay at rest (DAR). The oscillation channel ν̄μ→ ν̄e is investigated in the appearance mode with a 56 t liquid scintillation calorimeter at a mean distance of 17.7m from the ν–source looking for p ( ν̄e , e + ) n reactions. The cosmic induced backgrou...

We study the behavior of long-lived eventually suspended accounts in social media through a comprehensive investigation of Arabic Twitter. With a threefold study of (i) the content these accounts post; (ii) the evolution of their linguistic patterns; and (iii) their activity evolution, we compare long-lived users versus short-lived, legitimate, and pro-ISIS users. We find that these long-lived ...
