    摘要: A photonic radiation detection device includes a collimator, a detector, and localization means for determining information relative to the localization of a photon interaction with the detector material. In at least one previously selected acquisition configuration, a degree of pixelation in the detection plane is greater than 1 and a collimator-detector distance (C) is greater than one tenth of the septal height (h) of the collimator where the septal height is a maximum dimension of the collimator in a direction orthogonal to the frontal detection plane. In one instance, the septal wall thickness (e) is one of about 0.1 or less than about 0.1 of the channel width (w). In another instance, the collimator-detector distance is greater than h/(2(w/e−1)). A dimensioning method includes, for at least one given spatial frequency, calculating and comparing merit indicator values for different acquisition configurations of a structural model of the detection device.

    摘要: A method for producing a plurality of chips each comprising an individualisation region, each chip comprising at least: a first and a second level of the electrical tracks, and an interconnections level comprising vias. The method includes producing on the dielectric layer covering the first level a mask having openings located in line with the electrical tracks and making the dielectric layer accessible. The method includes producing, in a region of the chip comprising the individualisation region, patterns conformed so that: first openings of the hard mask are not masked by the patterns, and second openings of the hard mask are masked by the patterns. The method includes producing via openings in the dielectric layer in line solely with the first openings. The method further includes filling in the via openings with an electrically conductive material, and producing the second level of the electrical tracks on the vias.

    摘要: A device for synthesising core-shell nanoparticles by laser pyrolysis is provided. The device includes a reactor having a first chamber for the synthesis of the core, provided with an inlet for a core precursor, a second chamber for the synthesis of the shell, provided with an inlet for a shell precursor, and at least one communication channel between the two chambers to transmit the cores of the nanoparticles intended to be formed from the first chamber towards the second chamber. The device also includes an optical device to illuminate each of the two chambers, the device comprising at least one laser capable of emitting a laser beam intended to interact with the precursors to form the core and the shell. The device further includes at least a shell precursor inlet channel, one end of which is in the form of a distribution chamber surrounding the communication channel between the two chambers of the reactor, said distribution chamber being further provided, on its inner periphery, with at least one opening leading inside said communication channel.
