In order to cope with the significantly higher pile-up at the HLLHC, the tracking detector of the ATLAS experiment will be upgraded to an all silicon tracking detector, the ATLAS Inner Tracker (ITk), which will consist of a pixel detector in the innermost layers and a strip detector in the outermost layers. There are strong requirements on the ITk pixel detector to perform over ten years in the harsh environment at the HL-LHC, during which the ATLAS experiment is expected to record a dataset of 4000fb−1. The large number of modules in the ITk pixel detector in combination with the limited available space and the expected tracking performance make the design of this detector challenging, in particular the powering scheme and the transmission of the hit data from the front-end electronics to the readout backend at high data rates are more complicated than in the current tracking detector. The expected performance of the ITk pixel detector will, however, enable a rich physics programme, for instance a significantly improved understanding of the Higgs sector.","PeriodicalId":267466,"journal":{"name":"Proceedings of The 27th International Workshop on Vertex Detectors — PoS(VERTEX2018)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124395908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The LHCb experiment will be upgraded during the current shutdown (2019-2020) to a trigger-less system reading out data at 40 MHz event rate. To cope with the higher data rates and increased occupancy, the LHCb sub-detectors including the VErtex LOcator (VELO) need to be upgraded. The VELO is a Si microstrip detector that surrounds the interaction region and performs highly precise track and vertex reconstruction. The microstrip sensors in VELO will be replaced by hybrid pixel sensors having 55 × 55 μm2 pixels, that are bump-bonded to VeloPix ASICs. Module will be cooled by circulating evaporative CO2 coolant through microchannels etched in the Si substrate that provides mechanical support to the module components. The detector modules will be separated from the beam vacuum by 250 μm thick RF foil. Electrically working module prototypes have been built and rigorously tested at the assembly sites and at CERN SPS testbeam. This paper discusses the module components and design, electronic architecture, recent results and the current status of the VELO upgrade.","PeriodicalId":267466,"journal":{"name":"Proceedings of The 27th International Workshop on Vertex Detectors — PoS(VERTEX2018)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127781519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even so, the future experiments foresee these sensors to be exposed to higher radiation levels. Radiation induces a change in the macroscopic properties of the sensor, thus, severely affecting the sensor performance and ultimately becoming the limiting factor for its operation. With an aim to extend the radiation hardness capabilities of the silicon sensors for the future experiments there has been a growing interest in sensors with novel designs and unique characteristic of intrinsic charge multiplication. However, it is important to understand the effect of radiation damage on these sensors, before employing them in the main detector system. The RD50 collaboration extensively employs TCAD simulation tools for an indepth understanding and structural optimization of the newly proposed sensor technologies, complementing the measurement results. The simulation tools also provide an insight into the sensor operation both in the non-irradiated and the irradiated scenario by predicting the leakage current, full depletion voltage, charge collection, electric field, etc behavior. This has required the development of a radiation damage model within the simulation tools such that the measurements are well complemented. The details of the radiation damage modeling using two commercial TCAD tools – Silvaco and Synopsys, are discussed in this work.","PeriodicalId":267466,"journal":{"name":"Proceedings of The 27th International Workshop on Vertex Detectors — PoS(VERTEX2018)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127616550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
