A laser test system for characterizing CMOS active pixel sensors
No full textCMOS active pixel sensor suitability for radiation detection purposes has been already demonstrated. In particular, the adoption of a
fully standard deep sub-micron CMOS technology allows to obtain a very compact pixel size, an efficient integration of smart electronics
and ease of porting to future, more advanced, technology nodes. These characteristics potentially enhance the sensor capabilities, in
terms of spatial resolution and energy resolution. In order to verify such hypotheses, test chips have been fabricated, and a dedicated
laser test bench has been devised and implemented. The test bench features a mechanical movement section with sub-micron positioning
capabilities, and an optic axis with a beam-splitter that allows the fine focalization of a near infrared laser stimulus and also to obtain a
visible picture to control the irradiated region. A low-cost comprehensive active pixel sensor characterization can be therefore carried out
as an alternative to more expensive beam test characterizations
Design and test of innovative CMOS pixel detectors
No full textIn this work, design, implementation and test phases of a radiation sensor based on active pixel architectures are discussed. Fully standard CMOS technology has been exploited, allowing for easier integration of signal-processing circuitry. Alternative circuit schemes have been considered; a novel architecture, called WIPS, is introduced, aimed at a more efficient sparse-access mode of the sensor array. A first prototype of the chip has been fabricated, in a 0:18 mm CMOS technology. An automatic testing procedure has been devised, including design and fabrication of a suitable test board and of an optical bench. Preliminary results of the measurements are given, validating the overall approach and theoperatingprincipleoftheWIPSarchitecture

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
