Underground muography with portable gaseous detectors

open access: yesJournal of Physics: Conference Series, 2022
Muography is a novel imaging technology based on particle physics instrumentation to reveal density structure of hill-sized objects. The cosmic muon flux is attenuated while penetrating into the ground, thus the differential local flux correlates with ...

Optimized detector tomography for photon-number resolving detectors with hundreds of pixels [PDF]

open access: yes, 2023
Photon-number resolving detectors with hundreds of pixels are now readily available, while the characterization of these detectors using detector tomography is computationally intensive. Here, we present a modified detector tomography model that reduces the number of variables that need optimization.

Absolute self-calibration of single-photon and multiplexed photon-number-resolving detectors [PDF]

open access: yesPhys. Rev. A 98, 013811 (2018), 2017
Single-photon detectors are widely used in modern quantum optics experiments and applications. Like all detectors, it is important for these devices to be accurately calibrated. A single-photon detector is calibrated by determining its detection efficiency; the standard method to measure this quantity requires comparison to another detector.

Research and Development for a Gadolinium Doped Water Cherenkov Detector [PDF]

open access: yes, 2012
The proposed introduction of a soluble gadolinium (Gd) compound into water Cherenkov detectors can result in a high efficiency for the detection of free neutrons capturing on the Gd.

Pixel Detectors for Particle Detection and Imaging Applications [PDF]

open access: yesNucl.Instrum.Meth. A512 (2003) 277-288, 2002
Semiconductor pixel detectors offer features for the detection of radiation which are interesting for particle physics detectors as well as for imaging e.g. in biomedical applications (radiography, autoradiography, protein crystallography) or in Xray astronomy.

First prototype of a silicon tracker using an artificial retina for fast track finding [PDF]

open access: yes, 2014
We report on the R\&D for a first prototype of a silicon tracker based on an alternative approach for fast track finding. The working principle is inspired from neurobiology, in particular by the processing of visual images by the brain as it happens in ...

Horn-Coupled, Commercially-Fabricated Aluminum Lumped-Element Kinetic Inductance Detectors for Millimeter Wavelengths [PDF]

open access: yes, 2014
We discuss the design, fabrication, and testing of prototype horn-coupled, lumped-element kinetic inductance detectors (LEKIDs) designed for cosmic microwave background (CMB) studies.

Diamond Prototypes for the ATLAS SLHC Pixel Detector

open access: yes, 2009
Vertex detectors at future hadron colliders will need to cope with large particle fluences. Diamond is a particularly radiation hard material and exhibits further properties that makes it an attractive material for such detectors.

Quantum key distribution with "dual detectors" [PDF]

open access: yesPhysical Review A 75 052304 (2007), 2006
To improve the performance of a quantum key distribution (QKD) system, high speed, low dark count single photon detectors (or low noise homodyne detectors) are required. However, in practice, a fast detector is usually noisy. Here, we propose a "dual detectors" method to improve the performance of a practical QKD system with realistic detectors: the ...

Radiation hardness of small-pitch 3D pixel sensors up to HL-LHC fluences

open access: yes, 2017
A new generation of 3D silicon pixel detectors with a small pixel size of 50$\times$50 and 25$\times$100 $\mu$m$^{2}$ is being developed for the HL-LHC tracker upgrades. The radiation hardness of such detectors was studied in beam tests after irradiation
