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

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 ...

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 ...

An evaluation of the estimation of road traffic emission factors from tracer studies

Alain Clappier, Luis Carlos Belalcazar Ceron

Road traffic emission factors (EFs) are one of the main sources of uncertainties in emission inventories; it is necessary to develop methods to reduce these uncertainties to manage air quality more efficiently. Recently an alternative method has been propo ...

Estimation of road traffic emission factors from a long term tracer study

Alain Clappier, Luis Carlos Belalcazar Ceron, Erika Maria Zarate Torres, Minh Dung Ho

Road traffic emissions, one of the largest source categories in megacity inventories, are highly uncertain. It is essential to develop methodologies to reduce these uncertainties to manage air quality more effectively. In this paper, we propose a methodolo ...

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 ...

Inferences from catchment-scale tracer circulation experiments

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

In this paper the mechanisms determining the mobilization and transport of solutes driven by rainfall through runoff pathways at catchment scales are investigated through the analysis of tracer experiments. The hydro-chemical response of a small catchment ...

A new tracer technique for monitoring groundwater fluxes: The Finite Volume Point Dilultion Method (FVPDM)

Jordi Batlle-Aguilar

Quantification of pollutant mass fluxes is essential for assessing the impact of contaminated sites on their surrounding environment, particularly on adjacent surface water bodies. In this context, it is essential to quantify but also to be able to monitor ...

Producing over 100 ml of highly concentrated hyperpolarized solution by means of dissolution DNP

Arnaud Comment, Sami Jannin, Ruud van Heeswijk, Jacques Van Der Klink, Fiodar Kurdzesau

New low-temperature inserts compatible with an existing hyperpolarizer were developed to dynamically polarize nuclei in large samples. The performance of the system was tested on 8 ml glassy frozen solutions containing 13C-labeled molecules and doped with ...
