Physics and application of photon number resolving detectors based on superconducting parallel nanowires

Francesco Marsili, Alessandro Gaggero

The parallel nanowire detector (PND) is a photon number resolving (PNR) detector that uses spatial multiplexing on a subwavelength scale to provide a single electrical output proportional to the photon number. The basic structure of the PND is the parallel ...

Single-photon detector arrays for time-resolved fluorescence imaging

Marek Gersbach

Time-correlated single photon counting techniques have recently established themselves in numerous fields of research. In particular, for fluorescence lifetime imaging, time-correlated single photon counting is often considered the absolute reference in te ...

A Reply to the Comment by Byoung Jip Yoon. ...

2009

Radiation detectors based on the deposition of a 10 to 30 μm thick hydrogenated amorphous silicon (a-Si:H) sensor directly on top of integrated circuits have been developed. The performance of this detector technology has been assessed for the first time i ...

Consensus and collision detectors in radio networks

Seth Gilbert

We consider the fault-tolerant consensus problem in radio networks with crash-prone nodes. Specifically, we develop lower bounds and matching upper bounds for this problem in single-hop radios networks, where all nodes are located within broadcast range of ...

Focus-detector arrangement of an X-ray apparatus for generating projective or tomographic phase contrast recordings

Christian David

A focus-detector arrangement of an X-ray apparatus is disclosed for generating projective or tomographic phase contrast recordings of an observed region of a subject. In at least one embodiment, the arrangement includes a radiation source which emits a coh ...

2007

Site-specific radiation damage on anomalously scattering sites can be used to generate additional phase information in standard single- or multi-wavelength anomalous diffraction (SAD or MAD) experiments. In this approach the data are kept unmerged, down to ...

Absolute depth-dose-rate measurements for an 192Ir HDR brachytherapy source in water using MOSFET detectors

Rakesh Chawla

Reported MOSFET measurements concern mostly external radiotherapy and in vivo dosimetry. In this paper, we apply the technique for absolute dosimetry in the context of HDR brachytherapy using an 192Ir source. Measured radial dose rate distributions in wate ...
