“…These two critical components are shown in Figure 7. With the predecessor of ATLASPix-1 [16], the measured position resolution of σ x = 11.3 µm, the time resolution of 6.8 ns after the time walk and row delay corrections, and the power consumption below 300 mW/cm 2 are already close to the expected CEPC tracker requirements. ATLASPix-3 should provide improved performance and enriched functional-…”

The Circular Electron Positron Collider (CEPC) has been proposed as a Higgs factory to measure the properties of the Higgs boson with high precision and to enable the possibility to explore new physics. To meet the stringent physics requirements, it is necessary to design and construct both vertex and tracking detectors with the state-of-the-art silicon detector technologies. Initial R&D has been focused on CMOS pixel sensors to achieve both high position resolution and low power consumption. They are desirable for the vertex detector, which will sit closest to the interaction point and play a decisive role in precise determination of the primary and secondary vertices that are crucial for heavy flavor tagging. Recently, efforts have been also made to explore the possibility to design the large area silicon tracker with pixel sensors developed with high voltage CMOS technology, which promises both high position resolution and timing resolution. A short stave populated with the latest development of ATLASPix has been proposed for the demonstrator and sensor design tailored toward the CEPC tracker requirements are being pursued.

“…Single hit efficiencies for a fully monolithic HV-MAPS 1 irradiated with protons and neutrons were reported first for the MuPix7 predecessor [14] which has no radiation hard design. These performance studies have been repeated for the ATLASPix1_Simple prototype and first results were reported in [5]. Results from a more comprehensive study are summarized in the following.…”

High Voltage Monolithic Active Pixel Sensors (HV-MAPS) are based on a commercial High Voltage CMOS process and collect charge by drift inside a reversely biased diode. HV-MAPS represent a promising technology for future pixel tracking detectors. Two recent developments are presented. The MuPix has a continuous readout and is being developed for the Mu3e experiment whereas the ATLASPix is being developed for LHC applications with a triggered readout. Both variants have a fully monolithic design including state machines, clock circuitries and serial drivers. Several prototypes and design variants were characterised in the lab and in testbeam campaigns to measure efficiencies, noise, time resolution and radiation tolerance. Results from recent MuPix and ATLASPix prototypes are presented and prospects for future improvements are discussed.

“…Three generations of High Voltage CMOS (HVCMOS) monolithic sensor chips [1] have been designed in AMS/TSI 180 nm process to meet the requirements of ATLAS Inner Tracker (ITk) layer 4. The first generation ATLASpix prototype has proven high radiation tolerance of 1 × 10 15 n eq /cm 2 with 99.4% detection efficiency in a test beam study [2]. The design of ATLASpix sensors follows the large charge collection electrode topology.…”

ATLASpix3 is a 2×2 cm 2 high voltage CMOS sensor chip designed to meet the specifications of outer layers of ATLAS inner tracker. It is compatible with the hybrid pixel sensor ASIC RD53A in terms of electronic interface and geometry. ATLASpix3 is a depleted monolithic CMOS pixel detector which allows the construction of quad modules of the same size as that of hybrid sensors. The readout scheme can be externally configured as triggered or triggerless column drain readout. The hit information is transmitted through a 1.28 Gbit/s serial link. The interface is based on a single command input that is used for providing clock, trigger and configuration commands. This contribution summarizes the detector architecture with focus on the design of its readout circuitry. In addition, simulation results obtained using ReadOut Modelling Environment (ROME), that led to the design of the readout system are discussed.
