X-ray imaging detector for radiological applications adapted to the context and requirements of low- and middle-income countries

Jean-Philippe Thiran, René Salathé, Klaus Benedikt Schönenberger, Jérôme Schmid, Mario Andres Chavarria Varon, Hubert Blanchard, Romain Sahli, Sébastien Emmanuel Blanc, Matthias Hüser

This paper describes the development of a novel medical x-ray imaging system adapted to the needs and constraints of low- and middle-income countries. The developed system is based on an indirect conversion chain: a scintillator plate produces visible ligh ...

Radiation Performance of Highly Miniaturized Implantable Devices

Denys Nikolayev

Miniature wireless implantable bioelectronics provide powerful capabilities for biotelemetry, therapeutics, and neural interfacing. These technologies rely on antennas to communicate with external receivers, yet existing systems suffer from poor radiation ...

Studying the impact of radioactive charging on the microphysical evolution and transport of radioactive aerosols with the TOMAS-RC v1 framework

Athanasios Nenes

Radioactive charging can significantly impact the way radioactive aerosols behave, and as a result their lifetime, but such effects are neglected in predictive model studies of radioactive plumes. The objective of this work is to determine the influence of ...

Slow CH3NH3+ Diffusion in CH3NH3PbI3 under Light Measured by Solid-State NMR and Tracer Diffusion

Michael Graetzel, Joachim Maier, Alessandro Senocrate

We investigate methylammonium (MA) transport in MA lead iodide under illumination and show this, as in the dark, to be measurable but negligible when compared with the major carriers. H-1 and C-13 nuclear magnetic resonance (NMR) spectra show constant line ...

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 ...

Radiation protection studies for CERN Linac4/SPL accelerator complex

Egidio Mauro

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 ...

Design of a monitoring network over France in case of a radiological accidental release

Nikki Vercauteren

The Institute of Radiation Protection and Nuclear Safety (France) is planning the set-up of an automatic nuclear aerosol monitoring network over the French territory. Each of the stations will be able to automatically sample the air aerosol content and pro ...

Description of a dust particle detection system and measurements of particulate contamination from shock, gate valve, and ion pump under ultrahigh vacuum conditions

Dust particle contamination is known to be responsible for reduced quality and yield in microelectronic processing. However it may also limit the operation of particle accelerators as a result of beam lifetime reduction or enhanced field emission in radio- ...

Determination of absolute tool wear by γ-γ coincidence counting of radiotracers

Rakesh Chawla, Shaileyee Bhattacharya

γ-γ coincidence methods have been applied to obtain absolute flank and crater wear volumes from irradiated high speed steel (HSS) tools using 60Co as the radiotracer. Consistent absolute results can be obtained irrespective of the exact counting geometry o ...
