TransFEr: a new device to measure the transfer of volatile and hydrophobic organic chemicals across an in vitro intestinal fish cell barrier

Kristin Schirmer, Hannah Inka Schug

Transfer of compounds across cellular barriers is a critical step of compound uptake into organisms. Using in vitro barrier systems to evaluate such transfer is attractive because of the higher throughput and reduced resource needs compared to animal studi ...

A Nine Decade Femtoampere Current to Frequency Converter

Evgenia Voulgari

Various applications require ultra-low current sensing. Some of these applications are related to ionizing radiation detection. Radiation monitoring is important in particle physics experiments, nuclear facilities, hadron therapy institutes and hospitals. ...

Review of amorphous silicon based particle detectors: the quest for single particle detection

Christophe Ballif, Nicolas Würsch

Hydrogenated amorphous silicon (a-Si:H) is attractive for radiation detectors because of its radiation resistance and processability over large areas with mature Si microfabrication techniques. While the use of a-Si:H for medical imaging has been very succ ...

A front-end ASIC for ionising radiation monitoring with femto-amp capabilities

Evgenia Voulgari, François Krummenacher, Daniel Perrin

An ultra-low leakage current Application Specific Integrated Circuit (ASIC) called Utopia (Ultralow Picoammeter) has been designed and fabricated in AMS 0.35 mu m CMOS, in order to be used as the front-end for ionising radiation monitoring at CERN. It is b ...

Instrument intercomparison in the pulsed neutron fieldsat the CERN HiRadMat facility

Nikolaos Charitonidis, Daniel Perrin

An intercomparison of the performances of active neutron detectors was carried out in pulsed neutron fields in the new HiRadMat facility at CERN. Five detectors were employed: four of them (two ionization chambers and two rem counters) are routinely employ ...

A 120 dB dynamic-range radiation-tolerant charge-to-digital converter for radiation monitoring

Maher Kayal, François Krummenacher, Bernd Dehning

We present a radiation-tolerant 120 dB dynamic-range interface circuit for ionization chambers and diamond detectors. The device consists of a multi-scale continuous-time incremental charge-to-digital converter paired with a temperature-compensated current ...

Production of molecular sideband radioisotope beams at CERN-ISOLDE using a Helicon-type plasma ion source

In order to account for the increasing demand for strong molecular beams for nuclear physics experiments at ISOLDE, a new radioactive ion source concept based on an RE discharge in a magnetized plasma was developed at CERN. Experimental studies at the ISOL ...

Modelling oriented investigations of primary radiation damage in ultra high purity Fe and FeCr alloys

Anna Prokhodtseva

In the quest of the structural materials for the future fusion reactor, it has been shown that ferritic/martensitic (F/M) steels are very promising candidates, with a good radiation resistance in terms of damage accumulation in the microstructure relative ...

Performance of the LHCb muon system

Guido Haefeli, Giovanni Carboni

The performance of the LHCb Muon system and its stability across the full 2010 data taking with LHC running at root s = 7 TeV energy is studied. The optimization of the detector setting and the time calibration performed with the first collisions delivered ...
