Reactive Power Imbalances in LC VCOs and their Influence on Phase Noise Mechanisms

Phase-noise mechanisms in cross-coupled LC voltage-controlled oscillators (VCOs) are reviewed based on a physical understanding of reactive power imbalances in the tank and in the active part. These phenomena are proven to be the predominant phase-noise de ...

Towards data acquisition throughput increase in Fourier transform mass spectrometry of proteins using double frequency measurements

Yury Tsybin, Aleksey Vorobyev

Combined with high and ultra high pressure liquid chromatography, mass spectrometry-based peptide and protein structure analysis requires high resolution and mass accuracy achievable within short ion detection time. Although Fourier transform ion cyclotron ...

Nanoscale Optical Detector with Single-Photon and Multiphoton Sensitivity

Francis Lévy, Francesco Marsili, Alessandro Gaggero

We present the first nanoscale (down to approximate to 50 x 50 nm(2)) detector displaying single-photon sensitivity and a nanosecond response. This type of nanodetector can also be operated in multiphoton mode, where the detection threshold can be set at N ...

Phase extraction in dynamic speckle interferometry: proposal of a road map

Sébastien Equis

Of all the two-beam interference patterns, the ones obtained in speckle interferometry (SI) are the most difficult to be phase-demodulated. Many solutions exist in classical smooth-wave interferometry and alike techniques, both in static and dynamic regime ...

Capacitively coupled contactless conductivity detection with dual top-bottom cell configuration for microchip electrophoresis

Nico de Rooij

An optimized capacitively coupled contactless conductivity detector for microchip electophoresis is presented. The detector consists of a pair of top bottom excitation electrodes and a pair of pickup electrodes disposed onto a very thin plastic microfluidi ...

First spatial alignment of the LHCb VELO and analysis of beam absorber collision data

A first alignment of the LHCb Vertex Locator has been obtained from beam induced tracks at the LHC. A 450 GeV/c protons were collided on a beam absorber during the LHC synchronisation tests of the anti-clockwise beam in August and September 2008. The resul ...

Opportunities in microstructured photonics

Hans Peter Herzig, Toralf Scharf, Tristan Sfez

The progress in novel light sources, detectors, materials and technology enable new opportunities and challenges for diffractive optics and nanoscale photonics. Important are also analysis tools, such as near-field imaging (SNOM). Only structures that can ...

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 ...
