The radiation damage at the expected integrated luminosity of $4000;mathrm{fb}^{-1}$ and hadron fluencies over $2times10^{16};mathrm{n}_{mathrm{eq}}/mathrm{cm}^{2}$ requires a replacement of existing Inner Detector by an all-silicon Inner Tracker with a pixel detector surrounded by a strip detector. The ATLAS ITk detector will enable to bring Level-0 trigger rate of a few MHz down to a Level-1 trigger rate below 1 MHz at the peak instantaneous luminosity of $7.5times10^{34};mathrm{cm}^{-2}mathrm{s}^{-1}$ that corresponds to approximately 200 inelastic proton-proton interactions per beam crossing. The current prototyping phase, that is working with ITk Strip Detector consisting of a four-layer barrel and a forward region composed of six disks on each side of the barrel, has resulted in the ATLAS Inner Tracker Strip Detector Technical Design Report, which starts the pre-production readiness phase at the involved institutes. In this contribution we present the design of the ITk Strip Detector and current status of R&D of various detector components.","PeriodicalId":325789,"journal":{"name":"Proceedings of The 26th International Workshop on Vertex Detectors — PoS(Vertex 2017)","volume":"60 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":"125675280","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}

Several samples were irradiated with 24-GeV/c protons up to different fluences, ranging between 10$^{12}$ and 10$^{15}$ n$_textrm{eq}$/cm$^2$. This study concentrates mainly on the LGADs irradiated up to 10$^{14}$ n$_textrm{eq}$/cm$^2$. The measurements performed to characterise the devices include TCT, edge-TCT, TPA-TCT, and CV/IV measurements. The main goals of these studies were to analyse the voltage required to fully deplete the multiplication layer of LGADs; to measure gain degradation; and to investigate the distribution of the electric field inside the devices after irradiation, as well as the characteristics of the space charge. In order to do so, the measurements were performed under different temperature, read-out and biasing conditions. The obtained data confirm that in highly proton-irradiated LGADs the depletion of the bulk starts from the back electrode, thus shifting the onset of charge multiplication towards higher voltages. This is caused by a space charge sign inversion that is in turn accompanied by the appearance of a triple junction. Furthermore, it was found that annealing causes a recovery of gain along with a reduction of the multiplication-onset voltage towards unirradiated-like values.","PeriodicalId":325789,"journal":{"name":"Proceedings of The 26th International Workshop on Vertex Detectors — PoS(Vertex 2017)","volume":"21 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":"131059606","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 consists of three stations, 61$times$27 mm$^2$ each, which provide single-hit timing with 130 ps resolution. Each station is composed of a 200 $mu$m thick planar silicon sensor, segmented in 300$times$300 $mu$m$^2$ pixels, bump-bonded to 2$times$5 custom 100 $mu$m thick ASIC, called TDCPix. Each TDCPix contains 40$times$45 asynchronous pixels, and is instrumented with 360 pairs of time-to-digital converter channels with 100 ps bin. The three stations are installed in vacuum (about 10$^{-6}$ mbar) and cooled with liquid $mathrm{C_6F_{14}}$ circulating through micro-channels etched inside silicon plates a few hundred microns thick. The total material budget is less than 0.5% $X_0$ per station.

Our approach aims at keeping the number of fitting parameters as low as possible, at the same time accounting for new experimental evidences of relevant effects at these very high fluences (e.g. charge multiplication and avalanche effects). A physically grounded approach is being pursued, aiming at devising a not over-specific modelling while keeping predictive capabilities on the device behavior fabricated by different vendors (e.g. with different technology flavors) and in different operating conditions, e.g. at different fluences, temperatures and biasing voltages. The model development follows a test campaign with a twofold goal: from one hand, the relevant technology parameters such as oxide charge and interface trap states as a function of the irradiation dose have been measured. On the other hand, DC and AC measurements on gate-controlled diodes and MOS capacitors can be used as reference for TCAD simulation models validation purpose. The complete bulk and surface radiation damage model can be exploited for the analysis of the active behavior of different classes of new generation detectors to be used in the future HEP experiments.","PeriodicalId":325789,"journal":{"name":"Proceedings of The 26th International Workshop on Vertex Detectors — PoS(Vertex 2017)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130448743","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 tracking system consists of a station of silicon strip detectors and one of silicon pixel detectors on each side. The latter is composed of six planes of 3D silicon pixel sensors bump-bonded to the PSI46dig ROC developed for the CMS Phase I Pixel Tracker upgrade. A track resolution of $sim 10$ $mu$m is obtained.

Each timing station is made of three planes of diamond detectors and one plane equipped with an Ultra-Fast Silicon Detector (UFSD). A timing resolution of a few tens of picoseconds can be achieved with the present detector; a large R&D effort is ongoing to reach the $10$ ps target resolution.
