Characterization of Extended Range Bonner Sphere Spctrometers in the CERF high-energy broad neutron field at CERN

Nikolaos Charitonidis, Angelo Esposito, Marco Silari

The accurate determination of the ambient dose equivalent in the mixed neutron-photon fields encountered around high-energy particle accelerators still represents a challenging task. The main complexity arises from the extreme variability of the neutron en ...

Next decade of sterile neutrino studies

Alexey Boyarsky, Oleg Ruchayskiy

We review the status of sterile neutrino dark matter and discuss astrophysical and cosmological bounds on its properties as well as future prospects for its experimental searches. We argue that if sterile neutrinos are the dominant fraction of dark matter, ...

Experimental study and FLUKA simulations of a prototype micromegas chamber in a mixed neutron and photon radiation field

Nikolaos Charitonidis, Francesco Cerutti

Detectors based on the micromegas principle have already been used in several atomic, nuclear and particle physics experiments. They have also been proposed as one of the options to upgrade the ATLAS muon spectrometer in the very forward/backward region. T ...

Broadband Electromagnetic Characterization of Materials for Accelerator Components

Tatiana Pieloni, Carlo Zannini, Giovanni De Michele, Alexej Grudiev, Giovanni Rumolo

Electromagnetic (EM) characterization of materials up to high frequencies is a major requirement for the correct modeling of many accelerator components: collimators, kickers, high order modes damping devices for accelerating cavities. In this scenario, th ...

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 ...

Search for Higgs Bosons Decaying into Long-Lived Exotic Particles in the LHCb Experiment

Neal Gauvin

The four experiments of the Large Hadron Collider (LHC) at CERN have collected their first data at √s = 7 TeV, hailing an exciting era in particle physics. The LHCb detector is a single-arm forward spectrometer, dedicated to precision measurements of CP vi ...

Study and Experimental Characterization of a Novel Photo Injector for the CLIC Drive Beam

Öznur Mete

In this thesis, the transverse and longitudinal beam properties of the PHIN photoinjector are characterized. The objective of the research is to demonstrate the reliable and stable production of a 1.3 µs long bunch train, with 2.33 nC charge per bunch and ...

A transparent vacuum window for high-intensity pulsed beams

Juan Blanco Sancho

The HiRadMat (High-Radiation to Materials) facility will allow testing of accelerator components, in particular those of the Large Hadron Collider (LHC) at CERN, under the impact of high-intensity pulsed beams. To reach this intensity range, the beam will ...

Commissioning of the LHCb Inner Tracker and Measurement of V°-Particle Production in pp Collisions at 0.9 TeV

Mathias Oleg Knecht

The Large Hadron Collider (LHC) at CERN near Geneva is an accelerator designed to collide protons at a centre-of-mass energy of √s = 14 TeV. It is operational since November 2009 and has delivered collisions up to an energy of √s = 7 TeV in 2010. The LHCb ...

A novel approach to dielectrophoresis using carbon electrodes

Philippe Renaud, Rodrigo Martinez Duarte

Carbon-electrode dielectrophoresis (carbon-DEP) is demonstrated here as an alternative to more traditional DEP techniques. Carbon-DEP combines advantages of metal-electrode and insulator-based DEP by using low-cost fabrication techniques and low voltages f ...
