The Tracker Barrel with PS-modules (TBPS) is one of the subdetectors of the new CMS Phase-2 Tracker. It will have 2872 Pixel-Strip (PS) modules on three concentric layers. Each layer has three sections, one Flat section in the middle surrounded by two Tilted sections. In the Flat section the modules are on straight Planks while in the Tilted section they are on conical Rings. A particular...
The upcoming Electron-Ion Collider (EIC) at Brookhaven National Laboratory features a state-of-the-art time-of-flight barrel detector, comprising 144 staves that extend over a 2.7-meter length and support strip silicon sensors. Managing the thermal gradient along these staves is critical for optimizing sensor performance and is a primary focus of the design challenge. This research...
The pixel detector of CMS was re-installed in June 2021 after being stored in a clean room at Point 5 for the duration of Long Shutdown 2. This talk will cover the operational experience of preparing and installing the CMS pixel detector. It will highlight the tools and support rails used for installation, the connections for detector cooling and power, and how the detector’s temperature and...
Temperature control is an integral part of tracking detector mechanics. Keeping the silicon modules at safe working temperatures is imperative for favourable detector performance. However, cold operation requires specific design solutions to accommodate the thermal contraction of the pipes used in the cooling circuit. In ATLAS ITk, titanium tubes are used to cool the pixel detector modules...
Future particle accelerators present unique challenges for detector support structures, particularly in their innermost regions. These challenges require the development of novel structures with minimal mass, effective active cooling, high thermal conductivity, robust structural integrity, and shape stability under operational temperatures. Our research explores a novel design approach...
The upcoming Electron-Ion Collider (EIC) at Brookhaven National Laboratory features a proximity focusing RICH detector (pfRICH) in the electron-going endcap for particle identification ($\pi$/K/p as well as electron vs pion separation), comprising of enclosed gas volume held with solid carbon fiber end rings and a composite sandwich vessel. This talk highlights the prototyping efforts for the...
An approach of how to fabricate all 3 layers of end-rings with a common tooling plate is presented.
Abstract:
The TBPX project for CMS phase2, already presented in the Forum Mechanics 2021 online, is going ahead; in this talk the advance phases of the works and the first final prototypes are shown.
The procedures used to build, in Pisa, the first prototypes of the mechanical structures of Layer 1 and Layer4 TBPX will be presented.
Light structures cold plates made by 4 or 5 plies of high...
