These tracking devices, called beam telescopes, enable a precise measurement of the trajectory of charged particles with a position resolution of a few micrometer and an angular resolution of the order of a few ten microradian. In this contribution, the material budget of a structured aluminium cube is reconstructed from various estimators based on the deflection angles of simulated electron trajectories. Probing a target under various rotation angles enables a tomographic reconstruction of the target. \u0000We discuss the performance of width estimators of the scattering angle distributions and their impact on the contrast and the resolution of the reconstructed two- and three-dimensional images. At a voxel size of 0.1 mm $times$ 0.1 mm $times$ 0.1 mm, we reconstruct the material budget with a contrast to noise ratio of $5.6pm0.2$ and an edge resolution of about $(70pm10)$ micrometre.","PeriodicalId":325789,"journal":{"name":"Proceedings of The 26th International Workshop on Vertex Detectors — PoS(Vertex 2017)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125858142","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}

This will allow the ATLAS and CMS experiments to collect integrated luminosities of up to $3000,{rm fb}^{-1}$ during the project lifetime. To cope with this extreme scenario the CMS detector will be substantially upgraded before starting the HL-LHC, a plan known as CMS Phase-2 Upgrade. In the upgrade the entire CMS silicon pixel detector will be replaced and the new detector will feature increased radiation hardness, higher granularity and capability to handle higher data rate and longer trigger latency. In this report the Phase-2 Upgrade of the CMS silicon pixel detector will be reviewed, focusing on the features of the detector layout and on the development of new pixel devices.","PeriodicalId":325789,"journal":{"name":"Proceedings of The 26th International Workshop on Vertex Detectors — PoS(Vertex 2017)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130967792","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}

It is based on 50~$mu$m-thin MAPS sensors with a pitch of 20.7~$mu$m. The sensor is read-out in rolling shutter mode in 185.6~$mu$s. The 170 mW/cm$^2$ power dissipation allows for air cooling and contributes to reducing the global material budget to 0.4% radiation length on the innermost layer. This system took data in Au+Au collisions, p+p and p+Au collisions at $sqrt{s_{NN}}$~=~200~GeV at RHIC, during the period 2014-2016. Operational experience and lessons learned from the construction and the 3 years of data-taking will be presented in this paper. Detector performance and results from 2014 Au+Au data analysis, demonstrating the STAR capabilities of charm reconstruction, will be shown. Following this successful experience, the next-generation MAPS sensor, featuring an integration time shorter than 20~$mu$s, will be used to upgrade the ALICE Inner Tracking System (ITS) at LHC and has been proposed for the vertex detector (MVTX) for sPHENIX, the future nuclear physics experiment for the study of the QGP planned for RHIC.

An integral part of this project is the conceptual design of individual detector systems that can be operated under luminosities up to $3times10^{35} mathrm{cm}^{-2} mathrm{s}^{-1}$. Compared to HL-LHC scenario, one of the key limitations in the design arises from an increased number of pile-up events O(1000), c.f. O(140) at HL-LHC, making both particle tracking and identification of vertices extremely challenging. This paper reviews the general ideas that conceptually drive the current tracker/vertex detector design for the FCC-hh (proton-proton). These include material budget, detector granularity, pattern recognition, primary vertexing/pile-up mitigation and occupancy/data rates. Finally, the limits of current tracker technologies and requirements on their future progress, i.e. the dedicated R&D, are discussed.","PeriodicalId":325789,"journal":{"name":"Proceedings of The 26th International Workshop on Vertex Detectors — PoS(Vertex 2017)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116779524","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}
