The Fukushima Inverse Problem

Martin Vetterli, Ivan Dokmanic, Juri Ranieri, Robin Scheibler, Marta Martinez-Camara

Knowing what amount of radioactive material was released from Fukushima in March 2011 and at what time instants is crucial to assess the risk, the pollution, and to understand the scope of the consequences. Moreover, it could be used in forward simulations ...

Hyperpolarization without persistent radicals for in vivo real-time metabolic imaging

Mor-Miri Mishkovsky, Christophe Roussel, Andrea Capozzi, Jean-Noël Hyacinthe, Tian Cheng, Arnaud Comment, Najat Salameh, Yuhei Takado, Tim Rolf Eichhorn

Hyperpolarized substrates prepared via dissolution dynamic nuclear polarization have been proposed as magnetic resonance imaging (MRI) agents for cancer or cardiac failure diagnosis and therapy monitoring through the detection of metabolic impairments in v ...

Optimal control for Partial Differential Equations

Antoine Giovanni Imboden

In this project report, we first present the application of the finite elements method to the numerical approximation of elliptic and parabolic PDEs over two-dimensional domains. We then consider the theory and numerical approximation of optimal control pr ...

Radiological assessment of the Collimator Materials tests at HiRadMat in 2012

Nikolaos Charitonidis

A test for several collimator materials is planned to be performed in the HiRadMat facility of CERN/SPS. Before these samples can be brought to a surface laboratory for analysis after the irradiation, a certain cool-down period has to be respected in order ...

Experimental proposal Test of radiation protection instrumentation in HiRadMat

Nikolaos Charitonidis, Marco Silari

The knowledge of the response of radiation protection detectors in pulsed fields is very important, since this is a typical condition often encountered with stray radiation fields around particle accelerators at CERN and elsewhere. This document presents a ...

Effects of Radiation on MEMS

Herbert Shea

The sensitivity of MEMS devices to radiation is reviewed, with an emphasis on radiation levels representative of space missions. While silicon and metals generally do not show mechanical degradation at the radiation levels encountered in most missions, MEM ...

A 20-bit dynamic range CMOS A/D converter for ionization chambers

Maher Kayal, François Krummenacher, Bernd Dehning

We present the design of a wide dynamic-range CMOS A/D interface circuit for ionization chambers, able to digitize input charge of both polarities over six decades, to operate in a radioactive environment, and foreseen working without calibration. The circ ...

Prompt, Activation and Background radiation studies for the HiRadMat facility of CERN/SPS

Nikolaos Charitonidis

HiRadMat (High Irradiation to Materials) is a new facility under construction at CERN designed to provide high intensity beams in order to test raw materials and accelerator components with respect to the effect caused by the impact of pulsed, high intensi ...

Interaction between BaCO3 and OPC/BFS composite cements at 20 degrees C and 60 degrees C

Emmanuel Gallucci

A BaCO3 slurry, containing radioactive C-14, is produced during the reprocessing of spent nuclear fuel. This slurry is encapsulated in a Portland-blastfurnace slag composite cement. The effect of BaCO3 on the hydration of OPC and Portland-blastfurnace slag ...

Measurement of the atmospheric neutrino energy spectrum from 100 GeV to 400 TeV with IceCube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

A measurement of the atmospheric muon neutrino energy spectrum from 100 GeV to 400 TeV was performed using a data sample of about 18 000 up-going atmospheric muon neutrino events in IceCube. Boosted decision trees were used for event selection to reject mi ...
