CMS Inner Tracker Module Production and Qualification for the HL-LHC Upgrade
No full textThe High-Luminosity Large Hadron Collider (HL-LHC) operation will push the CMS experiment to its limits with a peak instantaneous luminosity of . This demanding environment will expose the CMS Inner Tracker (IT) pixel detector to unprecedented radiation levels and extreme hit rates. To withstand these conditions and manage the high pileup expected during operation, the new IT system features an optimized layout with thin silicon sensors, small pixel sizes, and fast, radiation-hard electronics based on advanced CMOS technology developed by the RD53 collaboration. Currently, pre-production modules are under construction, and extensive testing is ongoing to validate both the detector components and the associated quality control procedures. In the coming months, full-scale production of IT modules will
begin. This contribution provides an overview of the IT upgrade and summarizes the status of module production at the assembly sites, highlighting the results from testing and qualification
Improved Resistive Plate Chambers for Phase 2 upgrade of CMS
No full textIn view of the High Luminosity LHC, the CMS Muon system will be upgraded to sustain its efficient muon triggering and reconstruction performance. Resistive Plate Chambers (RPC) serve as dedicated detectors for muon triggering due to their excellent timing resolution. The RPC system will be extended up to 2.4 in pseudorapidity. Before the LHC Long Shutdown 3, new RE3/1 and RE4/1 stations of the forward Muon system will be equipped with improved Resistive Plate Chambers (iRPC) having, compared to the present RPC system, a different design and geometry and 2D strip readout. This advanced iRPC geometry configuration allows to improve the rate capability and hence to survive the harsh background conditions during the HL-LHC phase. Several iRPC demonstrator chambers were installed in CMS during the recently completed 2nd Long Shutdown to study the detector behavior under real LHC conditions. This paper summarizes the iRPC project and its schedule, including the status of the iRPC production sites, details of the chamber quality control procedures and results of the commissioning of the demonstrator chambers
Muon Detector Development for the CMS Phase-2 Upgrade and Muon Radiography Applications
No full textThis work contributed to the advancement of muon detector technology for the CERN Compact Muon Solenoid (CMS) experiment and explored broader applica- tions of muon detectors in interdisciplinary research. The CMS experiment at the Large Hadron Collider (LHC) is undergoing crucial upgrades in preparation for the upcoming high-luminosity phase of the accelerator. The research presented in this thesis includes the design and construction of new Resistive Plate Chambers (RPCs) to enhance the CMS muon system. To address the concerns related to the high global warming potential of the gas mixtures that are currently used in RPCs, alternative, eco-friendly mixtures were explored. Additionally, investigations were undertaken to study muon detectors for interdisciplinary applications, particularly for muon ra- diography—a technique utilising cosmic-ray muons to study the internal structures of large-scale objects. As part of a project to develop a light-weight, portable muon radiography telescope, small-size glass-RPCs were designed. Further insights into this imaging technique were gained through participation in the MURAVES project, where scintillator-based muon telescopes are used to study the internal structure of the active Mt. Vesuvius volcano near Naples, Italy

Improved resistive plate chambers for the upgrade of the CMS muon detector
No full textSeveral upgrades of the Resistive Plate Chamber (RPC) system of the Compact Muon Solenoid (CMS) experiment are currently being implemented to ensure a highly performing muon system during the upcoming High Luminosity phase of the Large Hadron Collider which will have an increased integrated luminosity of 3000 fb−1. The expected experimental conditions in that period present a challenge for the entire CMS detection system. To extend the RPC coverage, an improved version of the already existing RPCs will be installed in the forward region of the 3rd and 4th endcap disks. The current overall status of this CMS RPC upgrade project is presented
EFFECTIVENESS OF DIGITAL OCCLUSAL SPLINTS IN MANAGING TEMPOROMANDIBULAR JOINT DISORDERS: A SYSTEMATIC REVIEW AND META ANALYSIS
No full textBackground: This systematic review aims to assess the effectiveness of 3D occlusal splints (OS) for managing pain and improving maximum mouth opening in temporomandibular joint disorders (TMDs) via randomized controlled trials (RCTs). Materials and Methods: Searches were conducted in PUBMED, SCOPUS, and the COCHRANE library. Eligible studies were evaluated for risk of bias (RoB) by two reviewers based on predetermined criteria: generation of random sequences, implementation of single-operator protocol, inclusion of a control group, blinding of testing machine operator, uniformity in sample preparation, evaluation of failure modes, adherence to manufacturer's instructions for materials, and explanation of sample size calculation. If the author provided information about the examined parameter, the study was categorized as having a "YES." Conversely, if the information was absent, the parameter was marked as "NO." The RoB for each study was then determined according to the total number of "YES" responses: 1 to 3 indicated a high RoB, 4-6 signified a medium risk, and 7 to 8 indicated low RoB. Out of 14 articles, 5 RCTs underwent qualitative analysis. Results: Results indicate that OS therapy effectively manages TMD-related pain and reduces TMJ clicking. Additionally, it improves mouth opening in patients with initial limitations. Better symptom management correlates with improved quality of life in TMD sufferers. Conclusions: Further comparative clinical trials are necessary due to remaining uncertainties regarding how specific OS design and fabrication methods may impact TMD outcomes
An Invitation to Language: Fostering Critical Language Awareness Through Assignment Design
No full textFirst-year composition (FYC) instructors are often required to teach institution-issued course outcomes alongside their personal values. The author proposes a pedagogy to identify how teachers can invite rhetorical and linguistic agency in student writers and teach toward institutional objectives. To do so, the author shares her approach for revising existing and creating new FYC assignments that invite students to use their multiple codes and languagings (ways of communicating) in their writing. The assignments are driven by translanguaging approaches in writing instruction, specifically code-meshing and Critical Language Awareness (CLA), a theoretical framework coined by Shapiro, and integrate three settings in which languaging occurs naturally: family, music, and social media. The author revised or created an assignment that involves those settings to invite students to use their multiple languages and explains her pedagogical reasons for making those changes. The author argues for the importance of finding actionable ways to teach languaging through a rhetorical lens and extends an invitation to teachers of writers to use their agency to create a safe space for diverse student writers
