Counting efficiency determination from quantitative intercomparison between expansion and laminar flow type condensation particle counter

Aerosol Science and Technology, 2019
Heterogeneous nucleation of supersaturated n-butanol vapor on neutral silver particles of different size has been investigated at variable nucleation temperatures using a fast expansion chamber and a commercial continuous flow type condensation particle ...

Simple and Efficient Bilayer Cross Counting [PDF]

Journal of Graph Algorithms and Applications, 2002
Summary: We consider the problem of counting the interior edge crossings when a bipartite graph \(G = (V,E)\) with node set \(V\) and edge set \(E\) is drawn such that the nodes of the two shores of the bipartition are drawn as distinct points on two parallel lines and the edges as straight line segments.

Radioiodinated lipoproteins: absorption of 125I radioactivity by high density solutions.

Journal of Lipid Research, 1975
Concentrations of potassium bromide commonly used for separation of lipoproteins were shown to cause absorption of 125I and thus reduce the counting efficiency of the labeled lipoproteins.

High collection efficiency MCPs for photon counting detectors [PDF]

, 2017
Multi Micro-Channel-Plate Photomultiplier tubes (MCP-PMT) with High Collection Efficiency (Hi-CE) MCPs are developed and characterised. With these Hi-CE MCPs more than 90% of photoelectrons emitted from the photocathode can be detected; this is in ...

Quantum-scissors device for optical state truncation: A proposal for practical realization [PDF]

, 2001
We propose a realizable experimental scheme to prepare superposition of the vacuum and one-photon states by truncating an input coherent state. The scheme is based on the quantum scissors device proposed by Pegg, Phillips, and Barnett [Phys. Rev.
