This contribution describes the characterisation and validation campaign of the prototype of the CMS Readout Chip (CROC), a 65 nm CMOS pixel readout ASIC for the CMS Inner Tracker upgrade for High Luminosity LHC. This validation campaign includes tests with single-chip and multi-chip modules, irradiation campaigns, test beams and wafer-level tests. The main results obtained in the testing of the CROC prototype will be outlined. Key improvements and fixes that have been implemented in the final version of the chip before the October 2023 submission will be described.

In the high luminosity scenario of the LHC (HL-LHC), which will bring the instantaneous luminosity up to 7.5 × 10 34 cm −2 s −1 , ATLAS and CMS will need to operate at up to 200 interactions per 25 ns beam crossing and reaching up to 4000 fb −1 of integrated luminosity. To achieve their physics goals the experiments will need to improve the tracking and vertexing capability and the ability to selectively trigger on specific physics events at reasonable thresholds. The upgrade of the CMS Tracker requires designing new inner and outer tracking detectors to cope with the increased luminosity and to implement first trigger level functionality. This paper describes the new layout and the technological choices together with some highlights of research and development activities.

A new silicon tracker will be built for the Phase 2 Upgrade of the CMS experiment to fully exploit the increased luminosity delivered by the HL-LHC. The innermost part, called the Inner Tracker, will be exposed to extreme conditions such as unprecedented radiation levels of 1.2 Grad and 2.3×10 16 n /cm 2 and hit rate of 3.2 GHz/cm 2 . The new Inner Tracker relies on many novel solutions and technologies that allow for a design of a light and radiation-hard pixel detector of high performance. The hybrid pixel modules will be composed of pixel sensors with pixel size of 2500 μm 2 and a new ASIC, designed in 65 nm CMOS technology, developed by the RD53 collaboration. A novel scheme of serial powering will be deployed to power the pixel modules and new technologies will be used for a high bandwidth readout system. The mechanics will be lightweight, based on carbon-fibre material and two-phase CO 2 cooling. In this contribution, the design of the CMS Inner Tracker system will be presented along with the prospective design choices.
