The LHCb VELO detector is undergoing an upgrade, in which all its silicon sensors and electronics are being replaced, in order to cope with a triggerless readout scheme which also runs at 5 times higher luminosity compared to the previous LHC run. To achieve a better vertex reconstruction performance, the detector will be placed as close as 5 mm to the LHC beams protected against RF-pick up...

The upgrade of the LHCb experiment, currently being installed for the LHC Run 3, will transform the experiment to a trigger-less system reading out the full detector at 40 MHz event rate. All data reduction algorithms will be executed in a high-level software farm with access to the complete event information. This will enable the detector to run at luminosities of 2 x 1033 /cm2/s and probe...

The ATLAS PP1 patch Panel 01 is one of the most critical element in the ITK detector that has to guarantee the services interface, the gas tightness of the detector volume and the Faraday cage requirement. This talk presents the services design of manifolds and harnesses as well as the integration procedure. The sealing techniques and data-feedthrough leakrate measurements are presented and...

The Large Hadron Collinder (LHC) during its High-Luminiosity phase (HL LHC) is expected to deliver an integrated luminosity up to 4000fb$^{-1}$ and to reach an instantaneous luminosity between 5 and 7 times larger than the design LHC luminosity.
The ATLAS detector needs to upgrade its current subsystem in order to cope with this new experimental conditions. One of the most relevant...

The ATLAS Inner Tracker (ITk) of the phase-II upgrade programme is designed to meet the challenges at the high-luminosity LHC. The ITk silicon strip end-caps will cover the forward directions of the detector and consist of six disks populated with wedge-shaped silicon micro-strip sensors, divided in modules containing the readout, power and control electronics.

The decision to use small diameter, thin walled Titanium tubing for the ATLAS ITk upgrade detector cooling systems has presented ATLAS engineers with many challenges.
We at the University of Sheffield have been required to orbital weld Titanium tubing as small as 2.275mmn in diameter and with wall thicknesses at 160 microns. Titanium itself although being a strong and robust material is...

we started further test runs with a changed test setup to investigate operational behavior in detail.
We inserted capillary heaters to achieve a two phase CO2 cooling environment more similar to the Belle II PXD and upgraded the control structure.
We focused on temperature stability, response to load changes,... -

The TBPX detector is the barrel of its innermost part, called Inner Tracker (IT), and it is made out of four cylindrical layers, each 400 mm long, located between 30 mm and 146.5 mm away from the beamline.
Its mechanical design, starting from the... -

Purdue’s Composites Manufacturing and Simulation Center is responsible for manufacturing the inner tracker support tube (ITST) for the CMS high luminosity upgrade. Predicting the mechanical performance of the manufactured tube is necessary to ensure the success of the structure and guide preemptive redesigns. As preliminary validations of the modeling and simulation methods, scaled down ITST...

The CMS detector is going to be substantially upgraded during LS3 in order to exploit the increase in luminosity provided by the HL-LHC. The CMS Tracker for the Phase II will be populated by silicon sensors which are expected to operate at a temperature of about -20$^\circ$C. The cooling system have to maintain this setpoint value and remove the total power dissipated in the tracking volume...

The new outer tracker will be made of approximately 13000 silicon sensor modules called 2S modules (consisting of two parallel mounted silicon strip sensors) and PS modules (one pixel and a strip sensor combined in a module).
These modules provide... -

The CMS Tracker upgrade, to be installed prior to the high luminosity phase of LHC operation (HL-LHC), will require novel approaches to overcome the challenges posed by the extreme radiation environment. In addition, the tracker must remain extremely lightweight and at the same time provide an efficient cooling system (evaporative, CO2) capable of evacuating more than double the overall power...

For the high-luminosity LHC (HL-LHC), CMS will install a completely new silicon tracker. The future tracker will consist of two barrel parts and two endcaps (TEDD), one on each side. One endcap is made of five double-disks. One double disk is assembled from four half disks (Dees) on which the detector modules are mounted.
Dees are large and fragile objects, particularly after modules are...

In order to meet the increased thermal load associated with the enhanced detector chip designs, the CMS tracker upgrade will be cooled using two-phase CO2. In order to minimise radiation shadowing, 2 mm diameter thin walled (100 μm) cooling pipes will be used within the detector. This system operates at low temperatures (-35°C) and high pressures (typical operating pressures of 30 8 bar to 70...

With the ever-increasing use of Si-based detectors, balanced standalone environmental monitoring that can be also part of the detector DCS/DSS systems becomes a key issue both at the experimental cavern and at integration/production centers. We are presenting our work on one way of approaching this, based on the rapid progress of sensor conditioning circuitry and microcontrollers. We shall...

As the core detector of the CBM experiment at the under-construction FAIR facility, the Silicon Tracking System (STS) located in the dipole magnet ($1 T\cdot m$) provides track reconstruction ($> 95\%$) & momentum determination ($< 2\%$) of charged particles from the beam-target interactions (11 AGeV Au-Au).
Due to the expected non-ionising irradiation damage at the end-of-lifetime...

The Mu3e experiment searches for the lepton flavour violating decay µ→ eee with an ultimate aimed sensitivity of 1 event in 10$^{16}$ decays. This goal can only be achieved by reducing the material budget per tracking layer to X/X$_0$ ≈ 0.1 %. For this purpose, gaseous helium is chosen as coolant, while High-Voltage Monolithic Active Pixel Sensors (HV-MAPS) thinned to 50 µm constitute the...

The development of a proton computed tomography (pCT) detector is motivated by proton therapy, which is a novel treatment against cancer, based on the cell-killing effect of proton radiation. The planning of this treatment requires the 3D Relative Stopping Power (RSP) map of the patient, which is converted from Hounsfield Units, measured by X-ray computed tomography (X-ray CT). This conversion...
