We describe the design, fabrication, and use of a radio frequency reflectometer integrated with a microfluidic system, applied to the very high-throughput measurement of micron-scale particles, passing in a microfluidic channel through the sensor region. The device operates as a microfabricated Coulter counter [U.S. Patent No. 2656508 (1953)], similar to a design we have described previously, b...

For underground particle physics experiments, noble gas radon from U-chain decay series could be a source of serious background events. We have developed a high sensitivity detector for radon using electrostatic collection and PIN photodiode. Recently, we have developed a new type of radon detector. We report basic performance of the new 80L radon detector.

Scintillating crystal detector offers potential advantages in low-energy (keV-MeV range) low-background experiments for particle physics and astrophysics. The merits are discussed using CsI(Tl) crystal as illustrations. The various physics topics which can be pursued with this detector technology are summarized. A conceptual design for a generic detector is presented. PACS Codes: 14.60.Pq; 29.4...

The Hough transform [1] has recently received much attention as a powerful method of track finding in particle detectors. It has the strength of detecting track segments without having to put in much prior information about the location of the track segments. We present here an alternative algorithm where we show in a specific case how prior information of the tracks can be used to modify the H...

Recently, the marginalized particle filter (MPF) has been applied to blind symbol detection problems over selective fading channels. The MPF can ease the computational burden of the standard particle filter (PF) while offering better estimates compared with the standard PF. In this paper, we investigate the application of the blind MPF detector to more realistic situations where the systems suf...

The 13 th edition of History of On-Orbit Satellite Fragmentations, JSC-62530, has recently been published. This document details the 173 known breakups and 43 anomalous events of on-orbit objects from the first known breakup in June 1961 through 31 December 2003. This edition of the document discusses low Earth orbit and geosynchronous orbit spatial density, in-orbit and decayed object analysis...

ABSTRACT This paper describes a low power low noise mixed analog-digital PDFE (particle detector front-end) custom chip developed by IMEC for ESA and intended for scientific energetic particle space born instrumentation (spectroscopy). The ASIC (application-specific integrated circuit) is designed in a standard 0.7-μm CMOS process. The chip comprises a charge sensitive amplifier, a semi-gaussia...

The (Antares Modules for Acoustic Detection Under the Sea) AMADEUS system within the (Astronomy with a Neutrino Telescope and Abyss environmental RESsearch) ANTARES neutrino telescope is designed to investigate detection techniques for acoustic signals produced by particle cascades. While passing through a liquid a cascade deposits energy and produces a measurable pressure pulse. This can be us...

The project of upgrading the detector CMD-2 is presented. The upgraded detector is called CMD-2M and is going to take data with new collider VEPP-2000 at BINP. The general structure of the detector CMD-2 will remain as is but major parameters of the detector, such as momentum and angular resolution for charged particle and energy and spatial resolution for photons, will be substantially improved.
