The device designed, after passing a test-beam at CERN in 2003, is currently mounted on the end-ladders of the barrels of the Inner Tracking System of the ALICE DRIFT experiment, at CERN in Geneva. This project was developed in collaboration with the INFN Section of Turin (PASCAL and AMBRA chips).

High-energy physics experiments with accelerators.
A second and more recent activity is related to the ATLAS-Insertable B-Layer project. It is part of the upgrade project of the ATLAS pixel detector and in particular it refers to an additional pixel layer placed inside the existing 3 pixel layers of ATLAS. For this additional layer, the front-end electronics have been modified and are equipped with a new reading ASIC. This data acquisition chain was designed within the ATLAS collaboration (ATLAS-IBL).
- coordinator for the Bologna section of the INFN since 2012 for this specific development activity and in particular for the realization of the ROD (ReadOut Driver) card of the data acquisition system. This electronics is part of the phase 0 upgrade of all the ATLAS Pixel Detector c / o CERN in Geneva. For the ATLAS experiment IBL AG was the Sole Head of Procedure (RUP) and technical consultant for several tenders for the award of the contract for the production of complete and assembled boards, for a total of over 400 k € (MOF-B funds from CERN ).

Experiments for the detection of neutrinos. INFN's NEMO experiment has set itself as its objective the detection of very high energy galactic and extragalactic neutrinos by means of an underwater detector, the size of one cubic kilometer, which exploits the Cherenkov effect induced by secondary muons to muon neutrinos.

Experiments for the detection of charged particles for fast trigger systems. From 1994 to 1998 A. G. participated in the FUZZY experiment of the INFN which proposed the study and implementation of architectures integrated in fuzzy logic for possible applications to the triggers of high-energy physics experiments. Subsequently, from 2005 to today, the INFN SLIM5 and VIPIX experiments have led to the design of monolithic sensors including a pixel matrix and a sparsified readout logic for reading the space-time coordinates of the hits, with a resolution of the order of 1μs respectively. and 10μm. These researches have been oriented to the development of future fast trackers, also data-driven, for applications proposed in LHC and B-factory (SuperB) upgrade experiments.

Experiments with radiation-resistant microelectronic technologies. INFN's DACEL experiment had set itself the goal of designing and characterizing "deep sub-micron" structures in 130 nm CMOS technology for future applications in particle detectors and accelerators. For this experiment DACEL

- local coordinator for the Bologna section of the INFN in the years 2008-2009. In addition, the GBT project at CERN in Geneva is part of the "Link Radiation Hard Optical Project" which made it possible to develop a bi-directional rad-hard link for the upgrade of all LHC experiments. For this experiment GBT A. G. was “Project Associate” at CERN for the design of microelectronic components. In addition, the LEPIX experiment of INFN had set itself the goal of studying new pixel detectors (MAPS) that had at the same time the advantages of monolithic technology and the possibility of using emptied sensors to collect the electric charge by drift. For this experiment, LEPIX A. G. was the local coordinator for the Bologna section of the INFN in 2010.

Experiments for technology transfer. The INFN TOPEM experiment proposed the study of a multimodal time-of-flight platform, positron emision tomography and magnetic resonance imaging for the diagnosis and follow-up of prostate cancer. For this activity, the custom HPTDC and NINO chips used in the ALICE and CMS experiments of LHC have been re-proposed for the preliminary study of the time of flight, with a temporal resolution of less than 100ps, as a parameter associated with traditional measurements for PET.
- local coordinator for the Bologna section of the INFN in 2010 for the TOPEM experiment
- Group call 5 TIMESPOT. INFN's TIMESPOT experiment (2018-2020) aims to develop and implement a complete integrated system for tracking with very high spatial (100 μm) and temporal (100 ps) precision for each detection channel. For this experiment A. G. is local manager for the Bologna Section and responsible for workpackage “WP5: Design and implementation of high speed readout boards” for fast readout activities using the latest generation FPGAs.

- local coordinator for the INFN section of Bologna of the INFN DACEL experiment. This experiment aimed to design and characterize “deep sub-micron” structures in 130nm CMOS technology for applications in particle detectors and accelerators. These devices must be resistant to the radiation present in the accelerators and detectors in which they will be mounted. In particular, they must be immune to both total dose and single event effects. AG has also participated for the SLIM5 and VIPIX experiments in the design of a sparsified readout logic optimized in temporal performance, of the order of 1 μs, of monolithic active pixel sensors (MAPS) for applications in future thin silicon tracers with length of radiation less than 1% of the radiation length of the material

- local coordinator for the INFN section of Bologna of the INFN TOPEM experiment. This experiment aimed to study a multimodal TOf PEt (and SPECT) MRI platform for the diagnosis and follow up of prostate cancer. The Bologna group, in collaboration with the Bari and Genoa groups, has developed a semi-custom ASIC in mixed analog-digital CMOS technology, taking up the design of similar projects, already developed in other areas and designed for reading SiPM photosensors. . In this regard, the experiences gained in recent years have been made available for the design of readout prototypes for pixel arrays for SLIM5, VIPIX and SuperB. In particular, some ASICs designed for TOF measurements in LHC were considered. For these ASICs the potential was evaluated and an attempt was made to take design ideas for the specific ASIC project of this experiment. The Bologna group also provided the collaboration with the custom HPTDC and NINO chips used in ALICE for the preliminary study of the time of flight as a parameter associated with traditional PET measurements.

- local coordinator for the INFN section of Bologna of the LEPIX experiment of the INFN. This experiment proposed the development of fast and rad-hard monolithic pixel detectors implemented in standard 90 nm CMOS processes produced on moderate resistivity wafers. The Bologna group was involved for 2010, in collaboration with Bari, in the design of the digital elements of the demonstrator and actively participated in the tests of the prototypes created, installing the appropriate acquisition chain on site. The group has a solid experience in the development of firmware for FPGAs, which remains available for collaboration both for the realization of prototypes on FPGA of the control logic of the demonstrators and for any changes to the test systems.

- local coordinator for the INFN section of Bologna of the upgrade of the ROD (ReadOut Driver) card of the data acquisition system for the PIXEL and SCT experiments of ATLAS at CERN in Geneva. The candidate had individual responsibility, in particular within the Pixel Detector collaboration of ATLAS, for the production and hardware / firmware commissioning of the new readout cards (ROD) installed in the detector reading system.
In total, 150 ReadOut Driver (ROD) cards have been produced, already installed in layers IBL, 1, 2 and being installed in layer 0 and end-cap disks, to guarantee a higher reading speed of the ATLAS pixels with trigger over 100KHz and peak brightness higher than 1 * 1034cm-2s-1. The new Pixel Detector readout has thus contributed (and will continue to do so) to the acquisition of the statistics necessary for data analysis. In particular for the IBL layer (14 cards), for the Layer 2 (26 cards) and the Layer 1 (38 cards), the system is already in operation. For the B Layer (22 cards) and for the discs (12 cards), commissioning is in progress and will be completed in February 2018.

- Local Coordinator of Group Call 5 TIMESPOT. INFN's TIMESPOT experiment (2018-2020) aims to develop and implement a complete integrated system for tracking with very high spatial (100 μm) and temporal (100 ps) precision for each detection channel. For this experiment A. G. is the local manager for the Bologna Section and responsible for the workpackage "WP5: Design and implementation of high speed readout boards" for fast readout activities using the latest generation FPGAs.
