Bacterial matrix metalloproteases and serine proteases contribute to the extra-host inactivation of enteroviruses in lake water

Tamar Kohn, Virginie Bachmann, Marie-Hélène Chantal Corre

Enteroviruses are ubiquitous contaminants of surface waters, yet their fate in presence of microbial congeners is poorly understood. In this work, we investigated the inactivation of Echovirus-11 (E11) and Coxsackievirus-A9 (CVA9) by bacteria isolated from ...

Studies on the mechanical evolution of compacted bentonite subjected to environmental actions

Jose Antonio Bosch Llufriu

Deep geological disposal is currently the most feasible option for the long-term isolation of radioactive waste, consisting in emplacing the waste into tunnels or drifts excavated at great depths in suitable geological formations. The use of bentonite, a h ...

Sawtooth control with modulated ICRH in JET-ILW H-mode plasmas

Jonathan Graves

Sawtooth pacing with modulated ion-cyclotron resonance heating (ICRH) has been demonstrated to be very efficient in JET-ILW L-mode plasmas (Lerche et al 2017 Nucl. Fusion 57 036027, Lennholm et al 2017 Fusion Eng. Des. 123 535-40), where the main heat sour ...

First observation of spalling in tantalum at high temperatures induced by high energy proton beam impacts

Philippe Spätig, Elvis Fornasiere

Spalling in tantalum has been observed in an experiment aiming at testing an antiproton production target prototype at CERN’s HiRadMat Facility. The experiment consisted in impacting 47 intense and high-energy proton beams onto a target equipped with ten c ...

Shape staggering of midshell mercury isotopes from in-source laser spectroscopy compared with density-functional-theory and Monte Carlo shell-model calculations

Adriano Pastore, Annelies Marleen J Sels, Manorma Niermaladebhi Bender

Neutron-deficient Hg177-185 isotopes were studied using in-source laser resonance-ionization spectroscopy at the CERN-ISOLDE radioactive ion-beam facility in an experiment combining different detection methods tailored to the studied isotopes. These includ ...

The thermal triple-axis-spectrometer EIGER at the continuous spallation source SINQ

Henrik Moodysson Rønnow

EIGER is the new thermal triple-axis-spectrometer at the continuous spallation SINQ at PSI. The shielding of the monochromator consists only of non- or low magnetizable materials, which allows the use of strong magnetic fields with the instrument. This shi ...

Advanced materials characterization and modeling using synchrotron, neutron, TEM, and novel micro-mechanical techniques-A European effort to accelerate fusion materials development

Cécile Hébert

For the realization of fusion as an energy source, the development of suitable materials is one of the most critical issues. The required material properties are in many aspects unique compared to the existing solutions, particularly the need for necessary ...

Radiation shielding of a beta-beam rapid cycling synchrotron

Stefania Trovati

In a future beta-beam facility, radioactive ions (namely, 6He and 18Ne) are produced, accelerated, and then stored in a large decay ring, where they eventually produce neutrino beams through beta decay. Radiation protection is of great concern for this fac ...

Radiation protection studies for CERN Linac4/SPL accelerator complex

CERN is presently designing a new chain of accelerators to replace the present Proton Synchrotron (PS) complex: a 160 MeV room-temperature H- linac (Linac4) to replace the present 50 MeV proton linac injector, a 3.5 GeV Superconducting Proton Linac (SPL) t ...
