Abstract

Neutron imaging provides additional information to X-ray imaging and can be used in many applications, for example, nuclear engineering, non-industrial diagnostics and homeland security. This paper presents the latest development results of a new 3D structured pixel detector for thermal neutron detection and imaging. The device is based on Medipix/Timepix read-out chip family. The detector, without converter materials, was initially tested in the laboratory with a 241Am source, to simulate events that are induced by reaction products of active material in the silicon bulk. Thanks to the analysis of the size of event clusters and deposited energy, α particles and noise signals were discriminated. The detector was also tested with β and γ sources, to study the effect of other radiation on the device. These results can be useful as a starting point for future experiments, where a neutron source will be used, after filling the cavities with active materials, such as 6Li or 10B. In this paper, the results of the characterization and a comparison between experimental data and Monte Carlo simulations are shown.

Abstract

The ITk detector, the new ATLAS silicon tracking system for High Luminosity LHC, will be equipped with 3D pixel sensor modules in the innermost layer (L0). The pixel cell dimensions will be 25x100 μm² in the barrel and 50x50 μm² in the end-caps, with one read-out electrode at the centre of each pixel and four bias electrodes at the corners. Sensors from pre-production wafers (50x50 μm²) produced by FBK have been bump bonded to ITkPixV1.1 chips at IZM. Bare modules have been assembled in Genoa on Single Chip Cards and characterized in laboratory and at test beams. Few of these modules have been irradiated in Bonn and at the CERN IRRAD facility. Preliminary results of their characterization after irradiation will be shown, including measurements performed during SPS test beam campaigns in Summer 2022.

The device concept is studied and its performance is evaluatedby TCAD simulations, in comparison to the existing one. Although the modified designfeatures a less uniform electric field distribution, it is still expected to yield a very good timingperformance and high radiation tolerance, also exploiting charge multiplication effects.

Abstract

In the past few years, there has been an increasing interest toward 3D silicon radiation detectors. Owing to their unique architecture, 3D detectors provide a remarkable radiation hardness at relatively low bias voltage (hence low power dissipation), that makes them the most appealing solution for use in the innermost layers of tracking detectors in High Energy Physics (HEP) experiments. Besides this primary application, the use of 3D sensor technology has been extended also to other fields, like thermal neutron detection and microdosimetry for proton and ion therapy. In this paper, we will review the state of the art and on going efforts in 3D detectors, covering the main design and technological issues, as well as selected results from the experimental characterization and TCAD simulation.

Abstract

The growing interest toward the development of high‐Z–sensitized organic scintillators is related with the potential possibility to merge the advantages of organic materials with those of inorganics. In fact, organic plastic scintillators offer large‐area applications and fast response at a low cost, yet their performances for high‐energy photons and charged particles are limited by the poor stopping power related with low‐Z materials. The real‐time optical investigation in terms of steady‐state luminescence spectra of polysiloxane/quantum dot (QD) nanocomposite samples under 2 MeV proton irradiation is presented. Results show an increase in the light yield of the polysiloxane samples embedding QDs up to 8% in comparison with the undoped polymer, paving the way for high‐Z sensitization through QDs in polysiloxane‐based active radiation detection systems.

44. Development of 3D Silicon radiation detectors for neutrons and high energy charged particles

Author

Dalla Betta, Gian Franco, Mendicino, Roberto, Dalla Betta, Gian Franco, and Mendicino, Roberto

Abstract

In the past few years, several interesting developments in microstructured solid-state thermal neutron detectors have been pursued. These devices feature high aspect-ratio cavities, filled with neutron converter materials, so as to improve the neutron detection efficiency with respect to coated planar sensors. In the framework of the INFN HYDE (HYbrid Detectors for neutrons) project, we have designed new microstructured sensors aimed at thermal and fast neutron detection. Owing to the different cross section, neutron imaging is complementary to X-ray imaging allowing for a high contrast in soft materials. To this purpose, the possibility to have pixelated neutron detectors compatible with existing read-out chips (e.g., those from the Medipix/Timepix family) is an important goal that was achieved in this thesis. In this thesis the entire workflow will be described in detail, covering the design, simulations, fabrication and characterization of 3D neutron detectors for imaging produced at FBK. As a related topic, new 3D sensors for the "Phase-2" upgrades at High Luminosity LHC have been developed, and some aspects relevant to the device simulation and characterization are also reported in this thesis.

45. Development of Small-Pitch, Thin 3D Sensors for Pixel Detector Upgrades at HL-LHC

Author

Dalla Betta, Gian Franco, Sultan, D M S, Dalla Betta, Gian Franco, and Sultan, D M S

Abstract

3D Si radiation sensors came along with extreme radiation hard properties, primarily owing to the geometrical advantages over planar sensors where electrodes are formed penetrating through the active substrate volume. Among them: reduction of the inter-electrode distance, lower depletion voltage requirement, inter-columnar high electric field distribution, lower trapping probability, faster charge collection capability, lower power dissipation, and lower inter-pitch charge sharing. Since several years, FBK has developed 3D sensors with a double-sided technology, that have also been installed in the ATLAS Insertable B-Layer at LHC. However, the future High-Luminosity LHC (HL-LHC) upgrades, aimed to be operational by 2024, impose a complete swap of current 3D detectors with more radiation hard sensor design, able to withstand very large particle fluences up to 2×1016 cm-2 1-MeV equivalent neutrons. The extreme luminosity conditions and related issues in occupancy and radiation hardness lead to very dense pixel granularity (50×50 or 25×100 µm2), thinner active region (~100 µm), narrower columnar electrodes (~5µm diameter) with reduced inter-electrode spacing (~30 µm), and very slim edges (~100 µm) into the 3D pixel sensor design. This thesis includes the development of this new generation of small-pitch and thin 3D radiation sensors aimed at the foreseen Inner Tracker (ITk) upgrades at HL-LHC.
