A Radiation-Tolerant, high performance SPAD for SiPMs implemented in CMOS technology

We investigate the radiation effects on single-photon avalanche diodes (SPADs) fabricated in CMOS technology. For this investigation, a high-performance SPAD based on a vertical p-i-n construction with buried-N layer is proposed and used for the characteri ...

Characterization of GigaRad Total Ionizing Dose and Annealing Effects on 28-nm Bulk MOSFETs

Christian Enz, Claudio Bruschini, Farzan Jazaeri, Chunmin Zhang, Alessandro Pezzotta, Federico Faccio

This paper investigates the radiation tolerance of 28-nm bulk n and pMOSFETs up to 1 Grad of total ionizing dose (TID). The radiation effects on this commercial 28-nm bulk CMOS process demonstrate a strong geometry dependence as a result of the complex int ...

Low-Dose Prostate Cancer Brachytherapy with Radioactive Palladium-Gold Nanoparticles

Marc-André Fortin

Prostate cancer (PCa) is one of the leading causes of death among men. Low-dose brachytherapy is an increasingly used treatment for PCa, which requires the implantation of tens of radioactive seeds. This treatment causes discomfort; these implants cannot b ...

Automated computer-assisted quantitative analysis of intact murine lungs at the alveolar scale

Goran Lovric, Marco Stampanoni

Using state-of-the-art X-ray tomographic microscopy we can image lung tissue in three dimensions in intact animals down to a micrometer precision. The structural complexity and hierarchical branching scheme of the lung at this level of details, however, re ...

A multi-purpose imaging endstation for high-resolution micrometer-scaled sub-second tomography

Goran Lovric, Marco Stampanoni

Time-resolved imaging of dynamic processes, ranging from biological in vivo studies to materials under in situ and in operando conditions, requires a flexible endstation capable of controlling complex components that interact in different configurations an ...

GigaRad total ionizing dose and post-irradiation effects on 28 nm bulk MOSFETs

Christian Enz, Claudio Bruschini, Farzan Jazaeri, Chunmin Zhang, Alessandro Pezzotta, Federico Faccio

The DC performance of both n- and pMOSFETs fabricated in a commercial-grade 28 nm bulk CMOS process has been studied up to 1 Grad of total ionizing dose and at post-irradiation annealing. The aim is to assess the potential use of such an advanced CMOS tech ...

Impact of GigaRad Ionizing Dose on 28nm Bulk MOSFETs for Future HL-LHC

Christian Enz, Claudio Bruschini, Farzan Jazaeri, Chunmin Zhang, Alessandro Pezzotta, Federico Faccio

The Large Hadron Collider (LHC) running at CERN will soon be upgraded to increase its luminosity giving rise to radiations reaching the level of GigaRad Total Ionizing Dose (TID). This paper investigates the impact of such high radiation on transistors fab ...

Energy-selective neutron imaging for materials science

Steven Luc X Peetermans

Common neutron imaging techniques study the attenuation of a neutron beam penetrating a sample of interest. The recorded radiograph shows a contrast depending on traversed material and its thickness. Tomography allows separating both and obtaining 3D spati ...

Combination of UV absorbance and electron donating capacity to assess degradation of micropollutants and formation of bromate during ozonation of wastewater effluents

Urs von Gunten

In this study, the changes in UV absorbance at 254 nm (UVA(254)) and electron donating capacity (EDC) were investigated as surrogate indicators for assessing removal of micropollutants and bromate formation during ozonation of wastewater effluents. To meas ...
