This project is a continuation of previous projects of the National Plan led by IFCA and is presented as a coordinated project of three institutions: IFCA (UC-CSIC), IMB-CNM (CSIC) and ITAINNOVA. The purpose of the project is to contribute to the construction of the Inner Tracker and Endcap Timing Layer subdetectors for the upgrade of the CMS (Compact Muon Detector) experiment at CERN.
The operation of the detector during the high-light phase of the accelerator poses extraordinary difficulties both in the radiation resistance of the sensors (and their corresponding electronics) and in the reconstruction of traces and vertices, with a high multiplicity of traces and up to 200 inelastic interactions in each proton packet crossing. To mitigate these effects, CMS will use in the vertex detector or Inner Tracker (IT), pixel sensors highly resistant to radiation and with a higher granularity with respect to the current IT, manufactured in silicon using a 3D technology. In addition, a new detector called MTD (MIP Timing Detector) will allow to label with high temporal precision (of a few tens of ps) the traces coming from concurrent interactions, facilitating the discrimination of multiple vertices in each event. In the high-speed areas of the MTD, a detector called ETL (Endcap Timing Layer) will implement LGAD (Low Gain Avalanche Detectors) integrated gain silicon sensors.
In the specific case of the TI, this coordinated project proposes to develop sensors based on 3D pixel technology, intrinsically resistant to radiation, for the innermost layers of the TI, as well as to carry out technological developments to contribute to system and integration aspects, including serial power distribution, design and manufacture of high-density flexible interconnects (HDI) and studies of the power elements of the readout ASIC and electromagnetic compatibility. Finally, the integration of approximately 500 functional modules of the IT will be carried out and work will be done on aspects of detector optimization through simulations and trace reconstruction studies at the system level. Through these activities, the three groups will have the ability to jointly contribute to the CMS collaboration with complete fully functional 1×2 modules.
In the case of the ETL that will be instrumented with LGAD sensors, this project will integrate approximately 900 functional modules and will work on aspects of detector optimization through simulations and trace reconstruction studies at the system level.
