Description
The LHCb experiment at CERN is set to undergo a series of planned major upgrades to its detector system in the coming years, in preparation for the High Luminosity LHC. A new detector system for the downstream tracking stations, called Mighty Tracker, is proposed for installation during the long shutdown 4. The Mighty Tracker is of hybrid nature, comprising silicon pixels in the inner region and scintillating fibres in the outer region. The silicon pixels provide the necessary granularity and radiation tolerance to handle the high track density expected in the central region, while the scintillating fibres are well suited for the peripheral acceptance region. To address the needs of LHCb, a new monolithic High Voltage CMOS sensor called MightyPix is currently being developed for the silicon region. The MightyPix sensor, which is based on the High Voltage CMOS series MuPix and ATLASPix for the Mu3e and ATLAS ITk experiments, is specifically designed to meet the anticipated requirements in terms of pixel size, timing resolution, radiation tolerance, power consumption and data transmission among other parametres, while being compatible with the LHCb 40 MHz readout system. This presentation will cover recent progress towards MightyPix, including evaluation of fabricated prototypes and design towards the next chip iteration MightyPix2. The evaluation results will focus on lab and test beam measurements, obtained with the first fabricated MightyPix1 prototypes and precursor High Voltage CMOS chips before and after irradiation. The design efforts will also include emulating MightyPix on an FPGA to test and verify its digital readout. Additionally, remarkable recent advancements in the mechanical and electronic design of the silicon modules, which envision the use of serial powering, will be showcased. An overview of the current status of the whole Mighty Tracker project will be provided.
