Monolithic active-quenching and active-reset circuit for single-photon avalanche detectors
No full textAbstract—A monolithic circuit has been designed for ac-tive-quenching and active-reset of single-photon avalanche diodes (SPADs), which operate above the breakdown voltage BD for detecting single photons. To the best of our knowledge, this is the first fully integrated circuit of this kind ever reported. It can operate with any available SPAD device, since it generates pulses high enough to quench detectors biased up to 20 V above BD. The deadtime after each photon detection is adjustable; the minimum value is 50 ns, corresponding to 20 Mcounts/s maximum saturated photon-counting rate. The power dissipation is low (20-mW standby), suitable also for portable instruments. The small size and high reliability of the circuit make it possible to develop miniaturized detector modules and SPAD-array detector instruments. The circuit opens the path to new developments in many applications of photon counting, from DNA sequencing to ultrahigh-sensitivity imaging. Index Terms—Avalanche photodiodes, Geiger mode, photon counting, photodetectors, quenching circuits, single photon

L’isola di Arturo di Elsa Morante
No full textThe first two novels of Elsa Morante, Menzogna e sortilegio (1948) and L’isola di Arturo(1957), have always been considered texts without any recognizable relationship to their historical context, contrary to the view expressed by the author that any literary work of value will inevitably contain a portrait of its time. The aim of the present study is to cast light on those aspects of L’isola di Arturo that make it a typical product of the decade 1950-1960
