/ Liu, Shuaiyi (Beijing, Inst. High Energy Phys.) ; Feng, Mingjie (Beijing, Inst. High Energy Phys.)
/LHCb UP team Collaboration
The LHCb Upstream Tracker is a silicon strip tracking detector that started operation in the Run 3 of the LHC. To meet the requirements imposed by high occupancy and data rate at the HL-LHC, a new Upstream Pixel (UP) tracker is proposed for LHCb Upgrade II based on CMOS pixel sensors. [...]

Results of the new MAPS-based ALICE inner tracker operations in the LHC Run 3
/ Ravasenga, Ivan (CERN)
/ALICE Collaboration
The new ALICE Inner Tracking System (ITS2), installed in ALICE in May 2021 during a major upgrade campaign, significantly enhances the resolution on the determination of the distance of closest approach to the primary vertex, the tracking efficiency at low transverse momenta, and the read-out rate capabilities with respect to the previous tracker. It is equipped with silicon Monolithic Active Pixel Sensors (MAPS) with a pixel size of 27 × 29 μm2, a spatial resolution of 5μm and it features a material budget of 0.36 % X0 (inner layers). [...]

Study of built-in amplifier performance on HV-CMOS sensor for the ATLAS phase-II strip tracker upgrade
/ Liang, Z (UC, Santa Cruz, Inst. Part. Phys. ; Beijing, Inst. High Energy Phys.) ; Affolder, A (Liverpool U.) ; Arndt, K (Oxford U.) ; Bates, R (Glasgow U.) ; Benoit, M (Geneva U.) ; Di Bello, F (Geneva U.) ; Blue, A (Glasgow U.) ; Bortoletto, D (Oxford U.) ; Buckland, M (Liverpool U. ; CERN) ; Buttar, C (Glasgow U.) et al.
This paper focuses on the performance of analog readout electronics (built-in amplifier) integrated on the high-voltage (HV) CMOS silicon sensor chip, as well as its radiation hardness. Since the total collected charge from minimum ionizing particle (MIP) for the CMOS sensor is 10 times lower than for a conventional planar sensor, it is crucial to integrate a low noise built-in amplifier on the sensor chip to improve the signal to noise ratio of the system.

LHCb - Development of Upstream Tracker using MAPS for LHCb Upgrade II
Reference: Poster-2024-1172
Keywords: LHCb
Created: 2024. -1 p
Creator(s): Li, Yiming
The Upstream Tracker (UT) is a crucial component in the LHCb tracking system installed in the Upgrade I. The UT is a silicon microstrip detector that speeds up track reconstruction, reduces the rate of ghost tracks, and improves reconstruction of long-lived particles. LHCb is planning Upgrade II during Long-Shutdown 4 aiming at increasing the peak luminosity by a factor of 7.5. The event pile-up and occupancies will be far beyond the design of the current UT, while radiation damage and pattern recognition will also be challenging. The plan of a new UT using MAPS sensors is proposed. The major sensor technology options will be discussed. The digitization and simulation of the MAPS-based UT will be introduced. Based on the simulation, optmization of the system design is performed, and impact of various operation scenarios is studied.

Recent results and perspectives of the Monopix Depleted Monolithic Active Pixel Sensors (DMAPS)
/ Hügging, Fabian (Bonn U.) ; Barbero, Marlon (Marseille, CPPM) ; Barrilon, Pierre (Marseille, CPPM) ; Bespin, Christian (Bonn U.) ; Breugnon, Patrick (Marseille, CPPM) ; Caicedo, Ivan (Bonn U.) ; Degerli, Yavuz (IRFU, Saclay) ; Dingfelder, Jochen (Bonn U.) ; Hemperek, Tomasz (Bonn U.) ; Hirono, Toko (Bonn U.) et al.
The integration of readout electronics and sensors into a single entity of silicon in monolithic pixel detectors lowers the material budget while simplifying the production procedure compared to the conventional hybrid pixel detector concept. The increasing availability of high-resistivity substrates and high-voltage capabilities in commercial CMOS processes facilitates the application of depleted monolithic active pixel sensors (DMAPS) in modern particle physics experiments.
