Fully depleted thick CCDs have been designed for infrared astronomy, but their low read-out noise of the order of approximately 2 e− and their considerable mass of approximately 5.2 gr, allows novel uses for them in low energy threshold particle detection applications, such as the CONNIE and DAMIC experiments. In both experiments, the neutrinos or WIMPS will generate e-h pairs in a volume much less...
Technological solutions for the transfer to large area microstrip radiation silicon sensors are presented for the upgrade of the ATLAS detector. A new Automatic Layout Generation Tool has been developed to easily adapt the design of the sensors, investigating also the fabrication processes involved in 6-inch wafer technology. Inter-strip and radiation hardness characterization of prototype sensors...
This paper reports a tiny-sized (140μm×140μm) p-Si/Al infrared (IR) thermopile, which is low-cost bulk-micromachined only from the front-side of (111) wafer for IC-foundry compatible manufacturing. With the novel single-side bulk-micromachined structure, the tiny-size MEMS thermopile consists of six single-crystalline (SC) Si/Al thermocouples that show significantly higher Seebeck-coefficient and...
This paper shows the efficacy of a triangular active charge injection for resonant power supply noise reduction by measuring a real silicon chip. Based on the analysis of a triangular active charge injection, our circuit composed of a voltage drop detector, a finite state machine (FSM) and canceling capacitors injects the adequate amount of charge into the supply line of the LSI so that the core supply...
Finding correspondences between two images of the same scene or object, taken from different viewpoints and in different conditions, is a challenging task. Furthermore, in the analysis of scientific imagery, it must be possible in terms of human perception to appreciate detected local features, thus making the task even more complex. A renowned generic feature detector, Maximally Stable Extremal Regions...
The planned HL-LHC (High Luminosity LHC) expected to start in 2025 is being designed to maximise the physics potential of the LHC through a sizeable increase in the luminosity, reaching 1–1035 cm2s−1 after 10 years of operation [1]. A consequence of this increased luminosity is the expected radiation damage at an integrated luminosity of 3000 fb−1, requiring the strip part of the tracking detectors...
The Silicon Tracking System (STS) is the main tracking appliance of the future Compressed Baryonic Matter (CBM) experiment @FAIR. The STS employs double-sided silicon micro-strip sensors with double metal layers. An accurate detector model is a prerequisite for proper design and correct reconstruction of physical signals. In this report, we describe the hit reconstruction in the STS. Our detector...
TARANIS (Tool for the Analysis of RAdiation from lightNIng and Sprites) is a microsatellite aimed to atmospheric storms study. It embarks among other instruments IDEE (Instrument Detecteur d'Electron Energetique) which is dedicated to energetic electron characterization in the range from 70keV to 4Mev. To cover such awide ran ge, two types of detectors are required: Silicon (Si) and Cadmium Telluride...
The China Seismo Electromagnetic Satellite (CSES) aims to contribute to the monitoring of earthquakes from space. This space mission will study electromagnetic phenomena and their correlation with the geophysical activity. The satellite will be launched in 2017 and will host several instruments onboard: two magnetometers, an electrical field detector, a plasma analyzer, a Langmiur probe and an High...
Calorimetry at the High Luminosity LHC faces many technical challenges. In the forward direction the levels of radiation and the unprecedented in-time event pileup make detector design and operation particularly difficult. To meet these challenges, the CMS experiment has decided to construct a sampling calorimeter with silicon as the primary active medium. This calorimeter — the High Granularity Calorimeter...
The High Granularity Calorimeter (HGCAL) is the technology choice of the CMS collaboration for the endcap calorimetry upgrade planned to cope with the harsh radiation and unprecedented in-time event pileup projected at the High Luminosity-LHC era. In this context, profiting from fast-timing information with a resolution of a few tens of picoseconds embedded in the calorimeter would represent a unique...
A new Maia detector is being currently developed, consisting of an array of 384 silicon drift detectors (SDDs), each having an area of 1 mm2. The detector features a new double metal scheme that supplies biases to the pixel SDD rings. All 384 anodes of SDDs are meant to be connected to individual electronic channels. This effort was motivated by the need of improving the energy resolution and the...
SIRIUS is a state-of-the-art detector system for nuclear decay spectroscopy that will be mounted at the focal plane of S3 (Super Separator Spectrometer), which is part of the new SPIRAL2 facility at GANIL, Caen in France. Such a system requires high performance as it is dedicated to the study of very exotic nuclei. It is the result of collaboration between GANIL CSNSM, IRFU, and IPHC It is composed...

The ATLAS experiment is planning a major upgrade of its tracking detectors during the Phase-II LHC shutdown, to better take advantage of the increased luminosity of the HL-LHC. The layout of the Pixel Tracker is undergoing an optimisation and will be finalised in 2017. The various layouts are presented. A description of the supporting structures, along with results from testing of prototypes are also...
The probe arrangement in positron emission tomography (PET) is a combination of a high resolution detector (probe) placed within a whole body PET scanner. An additional subset of high-resolution data is recorded that contains events where one of the annihilation photon pair interacted in the high resolution detector.

Particle Flow Algorithm (PFA) and highly granular calorimeters provide currently the best jet energy resolution, which is of primary importance for precise physics measurements at future colliders.
