“…The reason for the significant capacitance increase even after the simple inclusion of the SiO 2 layer was found to be due to the introduction of positive oxide charges at the Si-SiO 2 interface [39]. In fact, the model that we adopted foresees a significant positive oxide charge concentration Q ox = 6.5 • 10 10 charges/cm −2 already at dose = 0.…”

“…The upcoming ARCADIA engineering run will include different design flavours of FD-CMOS monolithic sensors, both pixelated and strip-like. Large-area (1.3 × 1.3 cm 2 ) pixel demonstrators with embedded CMOS electronics and pixel test structures (0.5 × 0.5 and 1.5 × 1.5 mm 2 ) without integrated readout circuitry [39] are foreseen, with pitches ranging from 10 to 50 µm. The test structures will include as well the innovative MAMS and will allow a detailed characterisation of these sensors.…”

“…In this Section, the simulations performed to extract the sensor electrical characteristics and to study the charge collection dynamics are briefly illustrated. Shared definitions and conventions on simulation setups and operating parameters were agreed for the whole ARCADIA simulation campaign and are also described in [39].

The paper presents the simulation studies of 10 µm pitch microstrips on a fully depleted monolithic active CMOS technology and describes their potential to provide a new and cost-effective solution for particle tracking and timing applications. The Fully Depleted Monolithic Active Microstrip Sensors (FD-MAMS) described in this work, which are developed within the framework of the ARCADIA project, are compliant with commercial CMOS fabrication processes. A TCAD simulation campaign was performed in the perspective of an upcoming engineering production run with the aim of designing FD-MAMS, studying their electrical characteristics and optimising the sensor layout for enhanced performance in terms of low capacitance, fast charge collection and low-power operation. A very fine pitch of 10 µm was chosen to provide very high spatial resolution. This small pitch still allows readout electronics to be monolithically integrated in the inter-strip regions, enabling the segmentation of long strips and the implementation of distributed readout architectures. The effects of surface radiation damage expected for total ionising doses of the order of 10 to 10 5 krad were also modelled in the simulations. The results of the simulations exhibit promising performance in terms of timing and low power consumption and motivate R&D efforts to further develop FD-MAMS; the results will be experimentally verified through measurements on the test structures that will be available at the beginning of 2021.

“…At the time of writing, power consumption as low as 20 mW/cm 2 has been measured for payloads on instrumented areas as large as hundreds of cm 2 . Prototypes of next-generation Fully Depleted MAPS are available with power consumption reduced to 5 mW/cm 2 for squared pixel layouts and <1 mW/cm 2 for striplike sensing elements (typical dimensions of 25 µm × 500 µm) [155]. A striplike geometry is particularly relevant for an application where different spatial resolutions are required-for example, in ALADInO-to measure bending and nonbending coordinates.…”

Design of an Antimatter Large Acceptance Detector In Orbit (ALADInO)

A new generation magnetic spectrometer in space will open the opportunity to investigate the frontiers in direct high-energy cosmic ray measurements and to precisely measure the amount of the rare antimatter component in cosmic rays beyond the reach of current missions. We propose the concept for an Antimatter Large Acceptance Detector In Orbit (ALADInO), designed to take over the legacy of direct measurements of cosmic rays in space performed by PAMELA and AMS-02. ALADInO features technological solutions conceived to overcome the current limitations of magnetic spectrometers in space with a layout that provides an acceptance larger than 10 m2 sr. A superconducting magnet coupled to precision tracking and time-of-flight systems can provide the required matter–antimatter separation capabilities and rigidity measurement resolution with a Maximum Detectable Rigidity better than 20 TV. The inner 3D-imaging deep calorimeter, designed to maximize the isotropic acceptance of particles, allows for the measurement of cosmic rays up to PeV energies with accurate energy resolution to precisely measure features in the cosmic ray spectra. The operations of ALADInO in the Sun–Earth L2 Lagrangian point for at least 5 years would enable unique revolutionary observations with groundbreaking discovery potentials in the field of astroparticle physics by precision measurements of electrons, positrons, and antiprotons up to 10 TeV and of nuclear cosmic rays up to PeV energies, and by the possible unambiguous detection and measurement of low-energy antideuteron and antihelium components in cosmic rays.

“…Trying to provide an alternative solution based on the approach proposed in [11], the goal of the ARCADIA project is the development of FD MAPS employing a commercial 110 nm CMOS production process, targeting medical imaging, HEP and space applications. Preliminary TCAD simulations have been performed in order to evaluate the possible sensor design solutions and select the most promising layouts in test structures [12][13][14]. The passive pixel arrays included in the first engineering run of the ARCADIA project have been characterized from the electrical point of view, extracting the operating voltage range and the pixel capacitance values for the different pixel pitches and layouts.…”

Monolithic Active Pixel Sensors (MAPS) represent one of the most promising technologies for the next generation of radiation detectors. The ARCADIA project aims at the development of Fully Depleted (FD) MAPS employing a production process compatible with a 110 nm commercial CMOS technology. The first engineering run of the project included matrices of active pixels with embedded analog and digital frontend electronics and passive test structures such as passive pixel arrays, MOS capacitors and backside diodes. Although the produced samples were already characterized from the electrical point of view, a thorough study of the charge collection dynamics of the passive pixel arrays was still missing. In this paper we show the results of the dynamic characterization of a group of passive pixel arrays with different pixel pitches (50, 25 and 10 μm) and different pixel layouts. The tested samples have been illuminated from the backside with an infrared and a red laser with wavelengths equal to 1,060 nm and 660 nm, respectively. The pixel arrays have been mounted on a custom readout PCB connected to an external amplifier with 1 GHz bandwidth and the signals have been acquired through a fast digital oscilloscope. We employed both focused and unfocused laser spots to evaluate the change in the measured signal as a function of the laser spot position and the average response of the pixel arrays. An excellent agreement has been demonstrated by comparing the measured signals with the results of transient TCAD simulations and a time for 50% charge collection of 7.8, 4.2 and 2.6 ns has been predicted and experimentally validated in pixels with 50, 25 and 10 μm pitch, respectively.
