The\u0000LHCb collaboration is exploiting these technology advancements in various ways\u0000to enhance its capability for complex data reconstruction in real time. Amongst\u0000them is the real-time reconstruction of hits in the VELO pixel detector, by\u0000means of real-time cluster-finding embedded in the readout board firmware. This\u0000reconstruction, in addition to saving data-acquisition bandwidth and high-level\u0000trigger computing resources, also enables further useful applications in\u0000precision monitoring and diagnostics of LHC beam conditions. In fact, clusters\u0000of pixels, being more reliable and robust indications of physical particle hits\u0000than raw pixel counts, are also exempt from the complications associated to the\u0000reconstruction of tracks, that involves alignment issues and is sensitive to\u0000multi-layer efficiency products. In this paper, we describe the design and\u0000implementation of a flexible system embedded in the readout firmware of the\u0000VELO detector, allowing real-time measurement of cluster density in several\u0000parts of the detector simultaneously, and separately for every bunch ID, for\u0000every single LHC collision, without any slowdown of data acquisition.\u0000Quantitative applications of this system to luminosity measurement and beam\u0000monitoring are demonstrated.","PeriodicalId":501374,"journal":{"name":"arXiv - PHYS - Instrumentation and Detectors","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213717","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}

Single Photon Avalanche\u0000Diodes (SPADs), the key element of SiPMs, can now be manufactured in CMOS\u0000processes, facilitating the integration of a SPAD array into custom monolithic\u0000ASICs. This allows implementing features such as signal digitization, masking,\u0000full hit-map readout, noise suppression, and photon counting in a monolithic\u0000CMOS chip. The complexity of the off-chip readout chain is thereby reduced. These new features allow new applications for digital SiPMs, such as\u00004D-tracking of charged particles, where spatial resolutions of the order of $10\u0000mu m$ and timestamping with time resolutions of a few tens of ps are required. A prototype of a digital SiPM was designed at DESY using the LFoundry $150\u0000nm$ CMOS technology. Various studies were carried out in the laboratory and at\u0000the DESY II test-beam facility to evaluate the sensor performance in Minimum\u0000Ionizing Particles (MIPs) detection.

This paper\u0000introduces a novel 3-axis Hall-effect sensor element based on an inverted\u0000pyramid structure, realized by leveraging MEMS micromachining and CMOS\u0000processing. The devices are manufactured by etching the pyramid openings with\u0000TMAH and implanting the sloped walls with n-dopants to define the active area.\u0000Through the use of various bias-sense detection modes, the device is able to\u0000detect both in-plane and out-of-plane magnetic fields within a single compact\u0000structure. In addition, the offset can be significantly reduced by one to three\u0000orders of magnitude by employing the current-spinning method.
