61. Status of CMS phase2 TBPX detector mechanics: Layer 3 prototype and final External Cylinder construction and testing, thermal tests on the mechanical structure

Daniele Benvenuti (Universita & INFN Pisa (IT))

During CMS Phase 2, the Inner Tracker will be upgraded. The Barrel Pixel part (TBPX), the closest to the Interaction Point, consists of 4 layers of sensors at different radii with respect to the beam pipe. Each mechanic layer is connected to the outer one through a carbon peek flange on one side and through carbon peek rings on the other side. The whole structure is supported by the External...

20. Ultra-light ladder design for the CMS Inner Tracker TBPX Layer1 replacement

Pier Filippo Cianchetta (Universita e INFN, Perugia (IT))

17/06/2025, 09:40

This talk focuses on the current status of the design for a potential upgrade of the innermost layer of the CMS Inner Tracker (TBPX). Due to the high radiation levels expected, the innermost layer of the detector will need to be replaced midway through the High-Luminosity LHC (HL-LHC) program. This necessity creates an opportunity to develop and implement improved mechanical structures and...

32. HL-LHC CMS Barrel Timing Layer and Tracker Support Tube: Mechanical Loading Tests, Metrology, Integration and Installation Updates

Sushrut Rajendra Karmarkar (Purdue University (US))

The Barrel Timing Layer and Tracker Support Tube (BTST) is a 2.4-meter diameter, 5.3-meter long composite sandwich structure designed to provide primary mechanical support for the Barrel Timing Layer, Outer Tracker, and Inner Tracker detectors of the CMS detector for the HL-LHC. This presentation provides updates on mechanical loading tests, metrology, and simulation validations following a...

42. Overview of Joining Methods and Process Management in the Production of CO$_2$ Cooling Pipes for the TB2S detector - CMS Tracker Upgrade

Joao Batista Lopes (CERN)

17/06/2025, 11:10

This presentation will provide an overview of the joining methods used in the production of the CO$_2$ cooling pipes for the TB2S detector, part of the CMS Tracker Upgrade at CERN. It will focus on both brazing and soldering techniques applied to assemble the components, as well as the cleaning methods and manufacturing processes employed. The aim is to share key lessons learned during...

23. Experimental tests on TBPX cooling loops at different CO2 vapour qualities

Mr Lorenzo Bistoni (Universita e INFN, Perugia (IT))

17/06/2025, 11:40

This study presents experimental thermal tests on TBPX evaporators conducted at CERN, B186.
The primary objective is to validate the current design of the most critical cooling loops with an inner diameter of 1.6 millimeters and, in second instance, to evaluate the impact of vapor quality (VQ) and Heat Flux on the thermal performance and stability of the cooling circuits by examining various...

33. Temperature dependent thermal conductivity measurements and their effects on the thermal management predictions for CMS TFPX Dees

Benjamin Edward Pulver (Purdue University), Yuvraj Chauhan

17/06/2025, 12:10

We present measurements of the temperature dependent thermal conductivities for carbon composite laminates, thermal interface material, carbon foam and adhesives used for the construction of the Tracker Forward Pixel detector support structures as designed for the HL-LHC CMS upgrade project. The simulation set up for thermal performance using temperature dependent properties is described and...
