In the passive CMOS Strips Project, strip sensors were designed by a collaboration of German institutes and produced at LFoundry in 150 nm technology. Up to five individual reticules were connected by stitching at the foundry in order to obtain the typical strip lengths required for the LHC Phase-II upgrade of ATLAS or CMS trackers. The sensors were tested in a probe station and characterised...
We intend to develop monolithic active CMOS Strips sensors for particle tracking applications, using experience from a previous project with stitched passive CMOS sensors.
The project is open to further collaborators.
The RD50-MPW4, the latest HV-CMOS pixel sensor of the former CERN-RD50-CMOS group, enhances radiation tolerance, granularity, and timing resolution for future experiments like the HL-LHC and FCC. Fabricated by LFoundry in December 2023 using a 150nm CMOS process, it features a 64 x 64 pixel matrix with a $62 \times 62 \mu m^2$ pitch and employs a column-drain readout architecture. The previous...
With the next upgrade of the ALICE inner tracking system (ITS3) as its primary focus, a set of small MAPS test chips have been developed in the 65 nm TPSCo CMOS process. The Circuit Exploratoire 65 nm (CE-65) focuses on the important characterisation of the analogue charge collection properties of this technology. The latest iteration of sensor design in this line of development is CE-65v2,...
Monolithic CMOS silicon sensors represent an important innovation for high-energy physics experiments due to their cheaper production and assembly cost compared to hybrid ones. Indeed, in hybrid devices, the electronics and the sensor are produced on different silicon substrates, which must be later connected using bonding techniques. However, as far as the time resolution is concerned, the...
Monolithic Active Pixel Sensor (MAPS) are among the most promising options for vertex detectors in future lepton colliders. Manufactured in a TPSCo 65 nm CMOS imaging process, the Hybrid-to-Monolithic (H2M) prototype advances this sensor type in the context of high-energy physics applications. The design process employed a digital-on-top design flow, and studied the portability of hybrid pixel...
The experiment purpose is to get signals from the MPW4 monolithic active pixel sensor (MAPS) under femtosecond TPA laser excitation at different depths (z-scan mode) and positions (xy-scan mode) on the chip (backside illumination). At 1550 nm, the silicon is transparent below a light intensity threshold so the photoionization (light absorption) happens only around the focus point (voxel...
The project aims to develop key technologies for the vertex detector in future lepton colliders, with a focus on CEPC. This development is crucial for enhancing the physics potential of future lepton colliders.
The current design of the CEPC vertex detector employs curved MAPS technology, inspired by the ALICE ITS3 upgrade. However, new challenges arise in adapting this curved MAPS...
For the future era of high luminosity operation in LHCb experiment, the Upstream Tracker (UT) is planned to be upgraded to a higher granularity and radiation hard tracker. CMOS technology is a promising solution. Compared to hybrid silicon pixel sensors, CMOS processes enable smaller sensor sizes while maintaining a lower material budget. CMOS technology is also a potential candidate for the...
