High-Energy Physics at accelerators
Project description
In the field of high energy Physics at accelerators the Excellence Department is involved in two main upgrade projects of the CMS (Compact Muon Solenoid) experiment for the High-Luminosity Large Hadron Collider (HL-LHC) at CERN.
CMS Phase2 pixel upgrade for HL-LHC

The first project is focused on the design and construction of the new silicon pixel detector that will operate at HL-LHC.
The new pixel detector will be a crucial component for pattern recognition and track reconstruction under unprecedented particle fluxes and radiation levels foreseen at HL-LHC.
In this project the University of Torino, in strong collaboration with INFN, is primarily involved in the design of the new pixel readout chip (ROC) using a commercial 65nm CMOS technology within the framework of the CERN/RD53 collaboration.
A first full-size prototype (order of 2cm x 2cm) of the new pixel readout chip, named RD53A, has been submitted and extensively characterized in 2018-2019. Different architectures of analog front-end and digital pixel readout logic were developed inside the international collaboration RD53 and in May 2019 the final front-end architecture was chosen by the CMS collaboration opening up the phase of the design of the final chip, now referred to as C-ROC (CMS Read-Out Chip). A first pre-production version of this chip, containing all required functionalities to operate in the final system has been submitted in Februrary 2020 and succesfully tested through 2020-2021. Design activities of the final version of the chip are ongoing, with the production submission foreseen for end of 2022. The main features of this extremely sophisticated chips are: radiation tolerance up to 1 Grad TID, low power dissipation (1 W/cm2), low noise occupancy (10-6 at 1200 e– threshold), high hit rate (3 GHz/cm2) and trigger rate (1 MHz with 12.5 μs trigger latency) capabilities.
Beside developments in the design and characterization of the new pixel readout electronics the University of Torino, in collaboration with the Torino Section of INFN, is in charge of the assembling of the entire innermost barrel layer of the new CMS pixel detector. This activity involves the design of all mechanical components, the qualification and test of hundreds silicon wafers containing the final readout chip through wafer-level testing (WLT), the qualification of assembled modules containing the readout chips bump-bonded to hybrid silicon detectors and the assembling of the final barrel layer for the new pixel detector.
Thanks to Excellence Department founding resources, in collaboration with the INFN Torino, this project greatly benefits from the installation of a new professional semi-automatic wafer probe station Cascade Microtech CM300xi and of a new X-ray facility, both installed, commissioned and operating in the technological laboratory of INFN Torino.
This has allowed to start the calibration of the automated wafer testing procedure with the CM300 probe station that will be finalized using wafers from the next engineering run. Moreover, after the initial commissioning of the X-ray machine, started in January 2022, Univerisity of Torino will be also able to perform Total-Ionizig Dose (TID) irradiation tests on submitted ASICs.

Ultra-Fast Silicon Detectors and readout electronics for particle tracking

The second project involves the design, qualification and construction of the innovative MIP Timing Detector that will installed in the CMS experiment for HL-LHC. The new detector will allow to add high-resolution timing information for particle tracking over a wide pseudorapidity range in order to greatly reduce trigger rates under unprecedented pile-up conditions at HL-LHC.
The new detector is divided in a Barrel part and in two Endcap. The sensor technology that has been chosen in September 2019 by the CMS Collaboration to be used in the Endcap (almost 15 m2) is based on is based on the usage of Ultra-Fast Silicon Detectors (UFSD), an innovative detector technology with a long research tradition at University and INFN of Torino already started inb 2016 in sinergy with the CERN/RD50 collaboration.
UFSD detectors are based on the Low-Gain Avalanche Diode (LGAD) concept and optimized for timing in high-energy physics and medical physics applications. Different productions have been studied within this project. The main goal is to reach better than 40 ps timing resolution up to 1.5 x1015 neq cm-2 s-1. Few vendors are on the market: Hamamatsu (Japan), Fondazione Bruno Kessler (Italy), NDL (China), CNM (Spain). The Torino UFSD group has connections with all of them: in particular with FBK a strong collaboration is ongoing. In 2018 the main FBK production has been focused on the use of Carbon in the gain layer implantation to mitigate radiation effects and to preserve the timing resolution at high dose, and on the lithography technique to get sensors of large dimensions, typically 4 x 24 pads 3 mm2 each.
In 2019 a couple of new batch productions systematically addressed how to minimize the inter-pad regions in order to limit the sensor dead area and to optimize the p-stop doping to get better performances. Moreover the sensor geometries have been designed to properly match the front-end electronics in order to perform an appropriate system test. In this context Torino also actively contributed to the sensor design and optimization using professional Technology CAD (TCAD) simulation tools.
Beside the sensor design and characterization activities, the UFSD group in Torino, in collaboration with the INFN Torino ASIC design laboratory, is working on the development of custom front-end electronics for the readout of these sensors, aiming at applications that require very precise time tagging. An innovative low-power 20-channels readout chip for UFSD strip sensors targeting 30 ps timing resolution, named FAST (Front-end Amplfiers for Silicon detectors in Timing applications) has been implemented using a commercial 110nm CMOS technology.
Present silicon sensor technology allows to efficiently operate sensors up to 1016 neq/cm2. However, several future applications, such as tracking detectors in high-luminosity and high-energy particle physics experiments, monitors for particle therapy and nuclear fusion reactors, envisage the use of silicon sensors in environments with fluences exceeding 1017 neq/cm2. The goal of the Silicon Sensor for Extreme Fluences (eXFlu) project is to extend the range of operation of silicon detector up to fluences of 5×1017 neq/cm2. The idea behind this radiation tolerance exploits the saturation of radiation damage effects, observed above 5×1015 neq/cm2, in combination with two developments in sensor technology: (i) the use of thin sensors (20-30 μm), intrinsically less affected by radiation than thicker sensors, and (ii) the presence of internal signal multiplication (gain of 5-10), to compensate for the low signals generated in thin active volumes.
Several students at different levels (bachelor, master) and PhD students are contributing to both projects.

Project description
In the field of high energy nuclear Physics at accelerators the Excellence Department is involved in the development of innovative monolithic active pixel sensors (MAPS) and low-mass interconnections for power and signal distribution.
In the field of high energy nuclear Physics at accelerators the Excellence Department is involved in the development of innovative monolithic active pixel sensors (MAPS) and low-mass interconnections for power and signal distribution (in collaboration with LTU, Ukraine and FBK, Trento). The activities include the design of sensors with dedicated software packages (TCAD, AllPix2) running on the OCCAM facility, development of interconnection tools and characterisation set-up. Finally characterisation of integrated detecting systems.
The first project is the upgrade of the Inner Tracker System (ITS)of the ALICE (A Large Ion Collider) experiment at the CERN that will be installed during the 2019/2021 long-shutdown (LS2) of the LHC machine.
During 2018 and first months of 2019 the main activity in Torino has been the construction of the constituent elements of the outermost barrel layers of the new ALICE pixel detector. The building blocks of this detector are the ALPIDE chips. This chip has been implemented using a commercial 180 nm CMOS imaging process and contains both pixel sensors and readout electronics on the same silicon substrate.’?’€’?’The Torino group has initially contributed to the design of high-speed off-chip data transmission parts and of the Flex Printed Circuit (FPC) used to distribute power and signal to the sensors, along with the development of the overall assembly procedure for the outer barrel staves. The construction of the staves, coordinated by the Torino group, finished in December 2019. The staves are now assembled in half layers/half barrels, commissioned and installed in the ALICE experiment, since Spring 2021. S. Beole` is Project leader of the ALICE ITS since October 1st, 2020. Since February 2021 the Torino group is involved in the characterisation of Test Structure prototypes of the 65nm CMOS technology based monolithic pixel sensors for the ITS3 project. ITS3 represents an upgrade of the 3 innermost layers of the ALICE ITS. The new tracker foresees large area ultra thin silicon sensors bent in cylindrical shape. This will allow the reduction of the material budget to unprecedented values. Torino has the responsibility of the APTS OA (Analog Pixel Test Structure OpAmp) validation.
A second project foresee the usage of ALPIDE also for space satellite applications in the HEPD2/LIMADOU project, which was approved in 2019 as part of the CSES-02 space mission. This project intends to build a detector to measure charged particle flux fluctuations in the ionosphere.
The Torino group is involved in the design and construction of the particle tracker, made of ALPIDE chips as the ALICE ITS. The main responsibility of the Torino group is the design of the Flex Printed Circuit (FPC) which was finalised in 2019 and the production of at least 50 modules, each equipped with 10 ALPIDE chips. Moreover the Torino Group collaborates to the development of the tracker turrets and their characterisation. Indeed the characterisation procedure was developed in Torino on the basis of the one used for the ALICE ITS construction. The completion of the construction is foreseen for Fall 2022 and the satellite will be launched in 2023. The group also participate in the INFN/CSN5 ARCADIA (Advanced Readout CMOS Architectures with Depleted Integrated sensor Arrays) project, aimed at developing fully depleted CMOS sensors for different applications.

Project description
In the field of astroparticle Physics the Excellence Department is involved in the development of SiPM-based large-size telescopes for ground-based cosmic-rays experiments.
Silicon Photomultipliers (SiPMs) are promising competitors to traditional Photo-Multiplier Tubes (PMTs) in many astroparticle experiments. Thanks to their features, in particular their high photon detection efficiency, tolerance to high illumination level, small pixel size and robustness, SiPMs are already the baseline choice for the small-area telescopes of the next-generation ground-based Cherenkov Telescope Array (CTA) γ-ray observatory. Indeed, the application of such devices in focal planes with larger area is still challenging.
In this context the Torino cosmic-rays research group is involved in the CTA experiment and is proposing a new large-size camera instrumented with solid state sensors instead of PMTs for the future upgrades of the Large Size Telescope (LST) of the CTA experiment.
The main goal is to develop a large area photosensor (approx. 5 cm2) read as a single channel, capable to work with high noise rate (~500 MHz) and with a dynamic range from few photons up to few thousands. The idea is to analogically sum several 6×6 mm2 SiPM sensors (12-16) and to properly shape the output signal.
During 2018-2019, a new laboratory for SiPM characterization has been set up and a first prototype version, based on a discrete-component summing circuit, has been developed and tested. A second version of the prototype uses instead an ASIC for the analog sum, exploring SiPMs devices from different vendors (Hamamatsu, FBK, SensL).
In the next years (2020-2021) different prototypes will be built and tested. The best ones will be integrated in a SiPM-based camera module of the of CTA/LST detector for a direct comparison with the current PMT modules.

Project description
The innovative fast silicon sensors developed within WP1 represent an appealing alternative to gas ionization chambers commonly used for beam monitoring in hadron therapy. Sensitivity to single particles, limited thickness, fast time response and outstanding time resolution can be exploited for developing a new generation of faster monitoring devices to implement advanced delivery modalities.
As part of the WP1 the medical Physics group of the Excellence Department has extensively investigated the usage of segmented UFSD strip sensors for proton beam flux and energy measurements in particle therapy with the main purpose of developing innovative Treatment Planning Systems (TPS) and new verification devices.
This project was carried on in collaboration with the Torino UFSD research group for the development of sensors optimized for the envisaged application, and with the INFN Torino ASIC design laboratory for the developed of fast custom readout electronics for UFSD strip sensors targeting medical applications.
A 24-channels custom readout chip, named ABACUS (Asynchronous logic Based Analog Counter for Ultra fast silicon Strips), has been designed and prototyped in the framework of the MoVe-IT (Modeling and Verification for Ion beam Treatment planning) project using a commercial 110nm CMOS technology.
Dedicated UFSD strip sensors were designed, produced at the Fondazione Bruno Kessler (FBK, Trento, Italy), and fully characterized in laboratory and on clinical proton beams of the Centro Nazionale di Adroterapia Oncologica (CNAO, Pavia, Italy) and of the Centro di Protonterapia di Trento (Trento, Italy). It was proven that, in the energy range used in clinics, a counting efficiency above 98% can be achieved up to an average rate of 2 MHz per channel (up to 10 MHz using an online pileup correction method) and that an energy sensitivity corresponding to 1 mm range in tissues can be easily achieved with the coincidence of two sensors 70 cm apart.
Two detector systems were finally developed, the first to directly count the number of beam particles delivered with a sensitive area of 3x3cm2 and the second to measure the beam energy with Time-of-Flight (ToF) techniques.
After a successful characterization of the chip coupled to segmented UFSD sensors, the project is now exploring the possibility to use the already mentioned FAST chip, developed by the same ASIC design group, designed for the upgrade of the CMS experiment.
Beside this activity the group benefited from the Excellence Department founding resources to improve its equipment on γ-spectroscopy with high-purity germanium (HPG) sensors for environmental radio-activity measurements.
