CMS is a general purpose experiment, designed to study the physics of pp collisions at 14 TeV Large Hadron Collider (LHC). It currently involves more than 2000 physicists from 150 institutes and 37 countries. The LHC will provide extraordinary opportunities for particle based on its unprecedented collision energy luminosity when it begins operation in 2007.
Measurements of inclusive charged-hadron transverse-momentum and pseudorapidity distributions are presented for proton-proton collisions at $\sqrt{s} = 0.9 $ 2.36 TeV. The data were collected with the CMS detector during LHC commissioning in December 2009. For non-single-diffractive interactions, average transverse momentum is measured to be 0.46 ± 0.01 (stat.) (syst.) GeV/c TeV 0.50 TeV, pseudorapidities between --2.4 +2.4. At these energies, densities central region, dN ch/dη||η|<0.5, 3:48...
The upgrade of the LHC to High-Luminosity (HL-LHC) is expected increase design luminosity by an order magnitude. This will require silicon tracking detectors with a significantly higher radiation hardness. CMS Tracker Collaboration has conducted irradiation and measurement campaign identify suitable sensor materials strip designs for future outer tracker at experiment. Based on these results, collaboration chosen use n-in-p type sensors focus further investigations optimization that type....
The results of the CMS tracker alignment analysis are presented using data from cosmic tracks, optical survey information, and laser system at Tracker Integration Facility CERN. During several months operation in spring summer 2007, about five million track events were collected with a partially active Tracker. This allowed us to perform first silicon modules tracks three different statistical approaches; validate performance; test stability structures under various stresses temperatures...
During summer 2006 a fraction of the CMS silicon strip tracker was operated in comprehensive slice test called Magnet Test and Cosmic Challenge (MTCC). At MTCC, cosmic rays detected muon chambers were used to trigger readout all sub-detectors general data acquisition system presence 4 T magnetic field produced by superconducting solenoid. This document describes operation Tracker hardware software prior, during after taking. The performance detector as resulting from MTCC analysis is also presented.
The degradation of signal in silicon sensors is studied under conditions expected at the CERN High-Luminosity LHC. 200 μm thick n-type are irradiated with protons different energies to fluences up 3 · 1015 neq/cm2. Pulsed red laser light a wavelength 672 nm used generate electron-hole pairs sensors. induced signals determine charge collection efficiencies separately for electrons and holes drifting through sensor. effective trapping rates extracted by comparing results simulation. electric...
In March 2007 the assembly of Silicon Strip Tracker was completed at Integration Facility CERN. Nearly 15% detector instrumented using cables, fiber optics, power supplies, and electronics intended for operation LHC. A local chiller used to circulate coolant low temperature operation. order understand efficiency alignment strip tracker modules, a cosmic ray trigger implemented. From through July 4.5 million triggers were recorded. This period, referred as Sector Test, provided practical...
The high luminosity upgrade of the Large Hadron Collider, foreseen for 2026, necessitates replacement CMS experiment’s silicon tracker. innermost layer new pixel detector will be exposed to severe radiation, corresponding a 1 MeV neutron equivalent fluence up $$\Phi _{eq} = 2 \times 10^{16}$$ cm $$^{-2}$$ , and an ionising dose $${\approx } 5$$ MGy after integrated 3000 fb $$^{-1}$$ . Thin, planar sensors are good candidates this application, since degradation signal produced by traversing...
This paper presents experimental results showing that the energy contained in beta radiation can be harvested by using diodes. A single BPW34 photodiode generates around 12 pA dc, so enough to power integrated analog blocks.
Nowadays, the semiconductor market is growing exponentially in many sectors and more particularly applications of Internet Things (IoT) “harsh” environments. These so-called harsh environments result difficult operating conditions for electronics. To guarantee reliability operations such environments, devices must be tested specified extreme conditions. In case exposure to ionizing radiation, tests are generally carried out on specific facilities as a cyclotron. Unfortunately, access this...
